Hi - I am trying to calculate the power required to charge a battery in order to compare the energy requirements of an electric scooter versus an internal combustion scooter. The electrical scooter specifications state:(adsbygoogle = window.adsbygoogle || []).push({});

battery: 12V/50AH x 4

time to 90% charge: 4.5 - 6 hours

charger: 400W / 7A

Am I correct in assuming that to recharge a discharged battery to 90%, it would take 2.4 kWh (i.e. 400 W x 6 h)?

Thanks for any advice you can offer.
