How much does an electric motor scooter contribute to my electric bill?
Skylar L asked:
I have a Schwinn 750 watt Electric Scooter. I charge it about three times a week. I'm curious to know whether or not this has a significant effect on my monthly electric bill. I have to admit, though, I don't know much about electricity in general.

So I suppose my question is: How much energy does this thing actually use? How many kwh?

The charging transformer should read on the back what the volts and the amperage.Volts x AMPS= WATTS used.If you look on the power bill you will see what they charge per watt.

If you look into the owner manual, it’ll tell you how much electricity you will be using for a full charge.

First, estimate your average kWh cost. Look at your electric bill; it should tell you how many kWh you used that month. Take your total $ and divide it by your kWh total. This cost won’t be the actual incremental cost, but it should be close enough for this purpose.
Now your scooter: guesstimate how many hours you use it per month (you are the only one who can do that). Multiply the estimated hours per month you use the scooter by 0.75 (750 W divided by 1,000 W/kW) and multiply by a fudge factor of about 0.7 (an estimate saying you run at full power 70% of the time). The result should be an estimate of the kWh your scooter uses per month. Multiply that by your average cost per kWh and you should have a fair approximation.
For example: If you use your scooter 20 hours per month, then 20h/month times 750W divided by 1000W/kW times 0.7=10.5 kWh per month. If your power bill runs $100 per month and you use 1,000 kWh per month, then your average cost is $0.10 per kWh. So 0.10 $/kWh times 10.5 kWh = $1.05 per month. If you assume your battery charger loses about the same amount of power that it transfers, you can easily bump your estimate up to $2 per month.
