I was curious as to how much power a Level 2 residential charger takes. For comparison, a home Central A/C unit uses 3-5,000 watts of electricity.
A 115 volt level 1 charger uses 1,400-1,900 watts. (similar to a microwave or hair dryer) It takes between 20 and 48 hours to charge a discharged battery depending on the battery size.
A 230 volt level 2 charger uses 3,300-19,200 watts, (7,500 watts is similar to a clothes dryer) For example, running a 7.2 kW level 2 charger is equivalent to running 3 central AC units simultaneously.
It takes from 4-10 hours to fully recharge a battery depending on the size.
A commercial fast charger uses 50,000-350,000 watts while taking 20-45 min. to fully charge a battery depending on size. Fast chargers can wear out a battery packs faster over time. An occasion fast charge isn't an issue but daily fast charges could cause premature failure.
Food for thought before you pul the trigger.
