my roommates claim that my 400W ebike has increased the electricity bill by 100 euros, is that possible?
Posted by StunningBaseball5479@reddit | ebikes | View on Reddit | 151 comments
the electricity rate is 0.36 euros per kWh, I made my calculations again and again and it seems impossible that recharging that battery once in two days for two month could consume anything more than 12 kWh per month, is there any certain circumstance that something could cause it to consume more ? I want to be certain whether that I'm causing extra expenses on them (so that I take responsibility and pay extra to cover it) or whether they're wrong
Moist_Network_8222@reddit
100€ ÷ (0.36€ per kWh) = 278 kWh
278 kWh = 278,000 Wh
278000 Wh ÷ 400 W = 695 hours
There are about 720 hours in a month.
Literally not possibly for your ebike to cost 100€ in electricity per month because it would need to stop to charge occasionally.
tightcall@reddit
I don't pay that much for charging my Tesla every month, that's like my 3 month bill. The roommate is full of $hit.
Soft_Yellow1757@reddit
my EV made the electric bill go up under 50 per month, and i charge about 20 miles every single night- and i think that is less than that. For a while i shifted to charging at the office (stage 2) and that is only 40 a month (1 full charge per week)
RockstarAgent@reddit
Same happened with my past landlords. Started with $50 in electric- but they said since I worked from home (on a laptop) that I was using electricity all day - so it went up to $75. Then because they saw I had an AC unit (portable Toshiba 12000 btu) that went up another $100 (flat rate) in electric - then when I got an ebike - they said another $30- $1 a day- when that didn’t make any sense because I only used it during the week to get to work and didn’t need to charge more than like a couple hours at night and obviously nothing on the weekend.
While I did have a fridge, a tv, a conduction cooktop, an air fryer and a microwave- all of which I didn’t use every single day (other than the fridge) these people did not budge and showed me the electric bills as they went up and also showed how from the previous year what their rates had been then.
But this was an Airbnb with like 5 other tenants - including one who had a large desktop computer running day and night - and somehow they singled me out. BUT the worst part was they were quick to raise the amounts but didn’t adjust for when I started to go into work - and then also was out of the place by 7:30am and because I then started to work a 2nd job when I got a car - I was arriving around midnight- so essentially was using minimal electricity- wasn’t using the AC all day - and even when I got the car they didn’t adjust for not needing to charge the bike- and all this in a unit that had no water or bathroom. Only reason I didn’t gripe was because it was ultimately cheaper than anything anywhere by a large margin and I can adapt easily- as long as it was within my budget. But for nearly a $500 monthly electric bill for the whole home they were almost making half off me alone and even when I explained electricity was going up everywhere or showed them the math on using the AC 24/7 - they were top notch at just not budging. So I just told myself they were just trying to charge extra rent by just calling it electric use.
I had originally set myself on a 5 year plan. But because of this I left after about a year and a half - so their loss because I would have been a sure thing - that unit was awesome only because it was a standalone and the person who sold them that home had built it as his home office and had built it well- so much so that cooling and heating were very efficient- and I could be as loud as I wanted - which was great for me personally. I had installed a kitchenette and had “running water” with a combination of an electric pump and my bathroom was setup outside in a tent and a portable toilet - I’d take that to the local RV dump site -
But when I left - I hear from another tenant I stayed in touch with that they couldn’t find anyone interested- either they may have been charging too much or no one was like me- willing to adapt to the situation.

jakemac53@reddit
The charger probably only pulls 100-200 watts, so it's literally not possible. The 400w rating is the motor not the charger.
Superb_Raccoon@reddit
Which brings up an interesting point... what if the charger draws power all the time, at near charging rates.
I doubt it, but a badly designed or defective one might.
youandican@reddit
A charger won't be doing any such thing. If it did the charger would more then likely blow the internal fuse disabling it. if for some reason that didn't happen it would become really hot and become a true fire hazard. You would also probably notice the burnt rubber/plastic smell it would be putting off.
Superb_Raccoon@reddit
Funny, mine does not do that and it is 5A/120v
chiefvelo@reddit
It's likely only a 2amp charger. Those have been the most common .

CharacterWest4661@reddit
You might also factor in the conversion efficiently from plug to battery. The worst i have seen us a 20% loss.
Even so, worst case, I agree. Hardly possible
Online_Accident@reddit
They are trying to scam you. Lets take a fake and unrealistic scenario for example. In this scenario ur bike is directly attached to power plug in ur house and is running on 100% power 24/7
0,4kwh x 24 = 9,6kwh per day 9,6kwh x 28 = 268,8 kwh per month 268,8kwh x 0,36€ = 96,77€ Also i would say the real electricity cost for charging ur battery every other day would be lil over 2€ per month.
dougmc@reddit
Well, let's be more realistic, but still assume heavy usage: let's say he drains the battery 100% once every day.
Let's also say it's a good-sized battery and holds 750 watt hours.
Let's assume the charger is 85% efficient.
So 750 watt*hours * 30 days/month * 0.36 euros/watt*hour / 85% = 9.5 euros/month -- but I'll note that this is extremely heavy usage and would have him riding something like 2000 km/month.
causticcafe@reddit
I'd like to add that my *car* (Ioniq 5) uses about 100-125 kWh a month for around 1,200mi a month, which is approx. $30 on my rates, and I have the stats from my charger's app to back that up
evertgeorge@reddit
That makes a lot more sense, 1200 miles for a (in my case 1 full battery) would be a killer range and efficiency.
causticcafe@reddit
My car's battery is like 70kWh or something, I'd have to check the spec sheet again, so 125 would be somewhere around 500mi I think
evertgeorge@reddit
How is that possible how many kWh do you use per 100 miles.
I'm on around 50kwh per day.
causticcafe@reddit
I must’ve misremembered the mileage because I usually get about 3mi/kWh, which would be around 350mi. I don’t drive a ton.
SteazGaming@reddit

Sorry, your roommate is full of shit. Get something like a kill-a-watt meter and check the facts for yourself. in the US they are about $10.00 or about 8.65 euros. I have 2 ebikes that are charged all the time and it only cost me about 8.65 euros for the pair. If he is claiming 100 euros make him prove it. With something like a kill-a-watt meter you can prove he is not telling the truth.

At the rates you have given 100 euros would cover 277.8 kw/h. I don't know how big you're battery is but mine is 1kw, 277.8kw/h would charge 9 of those batteries everyday for a month.
smandroid@reddit
Maybe he's secretly bitcoin mining.
jaeric927@reddit
Only way they could come up with that number is if you were running a 400w device on mains power 24 hours a day for the whole month. Charging your battery is a tiny fraction of that. If I had the specs of your charger and battery and how often you need to charge it, I could do the math, but in all likelihood it's less than 6 euros per month.
ChemicalConclusion71@reddit
Get yourself Tapo smart wall plug with energy meter they’re like 25€ on Amazon, and you will find out exactly, btw your 400w motor has nothing to do with how much power you use to charge your battery, it’s your battery Ah and voltage will be nice if you’re share those details so we can calculate how much capacity your battery has and your charger A

¡Ni de coña! Tus cálculos son perfectos y tus compañeros se han columpiado muchísimo. Matemáticas básicas: una batería de 400Wh consume 0,4 kWh por carga completa. Si la cargas 15 veces al mes, son 6 kWh. Ponle que el cargador pierde eficiencia y gastas 8 kWh. A 0,36 €/kWh, cargar tu bici cuesta menos de 3 euros al mes. Para subir la factura 100 pavos tendrías que cargar un coche Tesla, no una bici. Que busquen a ver quién se ha dejado un radiador eléctrico encendido todo el invierno o si la compañía os ha cobrado una lectura estimada, porque tú no eres el culpable.

Efficient_Sundae_336@reddit
Be aware that if you battery charges let's say 400wh, the charger is taking a bunch more than 400wh from the outlet. There are losses in the adapter, the battery, the battery charge controller integrated in the battery, cables, connectors... Probably not a ton more, but may be 20 or 30% more depending how efficient everything is

Personal_Host_1788@reddit
Charging a 400 Wh battery will use some 500 Wh due to losses. So you can just multiply the number of charges by 18 cents and there you are.
Bikermec@reddit
Are you riding 40k km in that same time period? Because that's how much you'd have to cover to use up 100€ worth of electricity.
LimpPisskit@reddit
Overtime it would, my ebike 48x16 ah 20p to charge it max
inu-no-policemen@reddit
Absolute worst case with 75% efficiency and always going from zero to 400Wh:
400 / 0.75 * 30 = 16000Wh or 16kWh
16 * 0.36 = 5.76€
If you measure the actual consumption with a power monitor plug, it will most likely be quite a bit lower. The efficiency is likely a bit better. The battery is most likely not always completely empty. The capacity also may have gone down a bit.
Sounds like your roommates need more fiber in their diets.
subarujump@reddit
As others have said, that's ridiculous. I have dozens of electric riding toys and RC cars with multiple chargers running simultaneously. I even leave a couple of common charger plugs (like the Razor 3 pin) accessible outside for the neighbor kids to use when I'm not home.
There has been no obvious change in my electric bill, I'd say at most it probably runs a few dollars a month. It's not even measurable against the cost of running the central air during the peak summer heat.

I charge two electric bicycles (mine and wifes) in the garage. Our combined range per season is approximately 2,500 km (excluding January and February). The garage also uses power for an electric door, lighting, an amplifier for music, and charging Garmin devices and other tools. Total monthly consumption is 4 kWh, with the bikes accounting for 2 kWh. This means the electricity cost is only about 0.70 euros per month for two people to commute to work.

Honestly - my e-bike is very frugal . I live in a small flat , but my average electricity bill is on average £1.50 - £20 a day. I can’t say if the extra 59p spike is charging the battery ( one of my batteries is a Swytch Max+ - which has a 70mile range ) - it is possible - so even at this rate , that’s £3.50 a week ( £14 a month) . A lot less than £100 . But often - when I go on a long ride - Intake an extra shower - and that is the most expensive devise in my home in t earns of electricity use - so not all of that 50p is likely to be just charging . Hope this helps .

My bike does around 50km on 1kwh. (Bosch performance motor, 600W I think). At 0.36€ per kWh, that means 139km per €. So did you do 139*100= 13900km lately?

All the calculation methods are the best for setting out a logic based approach, but something you might also want to do is compare the bills from before you got the bike and the bills from after you got the bike to verify if there even is an increase to discuss.
If the roommate won't share those, that's a pretty big red flag about their willingness to deceive you.

Looks like the maths has been done and it wouldn’t be possible to use that much power charging you e-bike unless your battery was always out of power, always on charge AND always being ridden. Not possible.
However the electricity bill could have gone up for other reasons. Not sure where you live but colder weather could be a factor. Has anyone used the washing machine excessively or been running a new electric heater? A large inefficient dehumidifier maybe? These things are more likely to increase the electricity bill.

If we assume a 250W EU-spec motor with a 20% loss rate (that is, 250W of mechanical power takes 300W of electrical power- which is much less efficient than basically any electric motor made in the last 100 years), then even running it at maximum power plugged directly into the wall 24/7 for 31 days would only use €80.35 of electricity, and it actually wouldn't get to that point because this hypothetical motor would overheat and set itself on fire long before that. It's mathematically impossible for an e-bike to cost €100 a month to power. Assuming you're a real human being who rides your bike the way real human beings do, you're looking at almost certainly no more than €3 a month. Even charging the battery from completely dead to completely full every day for 31 days assuming a 25% loss rate for a total energy consumption of 500 Wh/day would only cost €5.58.
Jesusatemypants@reddit

Latter-Ad-1523@reddit
we can find the exact number if you get a kila watt meter. we can get close with knowing the battery capacity in terms of watt hours
lets say its a 48v x 15ah = 720wh
.36 per kwh x .72 = .2592 euro cost for one change
but that is assuming the charger is 100% and this is highely unlikely which means it will cost more. if the charger is not a power factor corrected charger it might cost about 40% more so maybe close to .36288 euros per charge
even if you charge it every day it would cost .36288 x 30 =10.8864 every month
have you math ready, then ask him/her to prove their numbers, they are either dumb, jealous or trying to scam.

400w24 hour 30days/ 1000 gives 288 kWh if the bike was plugged in going all out 24/7
Even with expensive electricity (by US standards) it comes to $60/Month.
Realistically you use it 3 hours/day mqx and it's at worst 75% effwcient in charging.
So $60/8 (for the three hours being 1/8 of a day)*1.33 for the efficiency gives about 10/month.

The 48v/25AH battery on my bike - and it's a big battery - Literally costs less than a quarter to charge.
Even if I charged it from 0-100% daily, which almost isn't even possible with the range the thing has, it'd only cost like $7 a month.
FCAlive@reddit
Have you been charging it 4,800 hours per day?
ZenerWasabi@reddit
I assume you mean 400Wh as the battery size, that is equal to 0.4kWh
Let's assume you charged that battery 15 times during the mo th, always form 0% to 100% .
That means you've used 0.4kWh * 15 = 6kWh of energy.
If the energy costs 0.38€/kWh, that's a grand total of:
6kWh * 0.38€/kWh = 2.28€
If you allow some headroom for a non perfect charge efficiency (let's say 90%) it's still no higher than 2.50€
Inciteful_Analysis@reddit
Assuming your battery is 400 Watt hours and you are not specifying motor power despite not using the correct unit label.
With 20% charging loss, that yields 0.5 kWh of electricity to charge from empty one time.
If you charge every other day, that's 15 charges per month for a total of 7.5 kWh of electricity. At the stated rate of 0.36 euros per kWh, that yields 2.7 Euros per month.
If you have a meter for measuring electrical consumption at the otlutlet (a $10 device called "Kill-a-watt"), show them the full consumption for one charge and then do the math.

Even assuming a large battery (52V 17Ah = 884Wh) you'd have to fully charge your ebike about 300 times a month to increase the bill by that much. If my math is right.

No. I have a 20ah 48v battery. It doesn't increase my electricity at all. Charging my battery does not consume much.

Absolutely full of shit. My 500W won't even cost more than €20 in an entire year

Charging my EV costs less than half that. So no, they're full of shit.

Some dude did the math on his surron and it was like 1.50usd in California.

How big is your battery? Assume 90% efficiency so that it takes 40kWH to put 36kWH into your battery. How much are you charging, how often?

My cargo bike has dual 725wh batteries. Even making the very pessimistic assumption that I used a full charge every two days, and the even more pessimistic assumption that the charger was 50% efficient, my bike would cost about 15 euro per month to charge. Your roommates are attempting to steal from you.

lol no

So far the only good use that I have gotten from AI is estimating how much money it costs to charge my bike. For me it was about 0.09 US dollars to go from 30% to 100% with my power utility and bike.

Sounds like they are trying to get some extra money from you. Compare the previous months bill to the current one with the increase and see what the truth is c

This wouldn't really tell you anything unless the climate was absolutely constant.
Otherwise it's just telling you the bill was different, not what caused the difference.

0.4 kWh battery @ .36 euro / kWh = .144 euro/charge. Let’s be really conservative just to prove the point: assume efficiency of ~75% and call it and assume full charge each time, call it 0.20 euros/charge. 30 charges over two months is 6 euros.

It doesn't your roommate is full of shit

✓ this is your answer. Also you can do math with the info you have if you need to be exact.
