Week 6 Session 13

Level 1 EV charging

• The rate of EV charging is 120 volts in Level 1.

• Most electric vehicles come with a cord and a control box attached to them for Level 1 charging.

• One can plug in the cord to a three-pin wall socket to begin charging.

• It takes about 8 to 12 hours to charge from 0 to 100 per cent at Level 1, depending on your EV battery capacity.

• You don’t need to necessarily install any additional hardware for this level of charging.

• The only downside of Level 1 charging is the long duration it takes to fully charge an EV.

Level 2 EV charging

• Level 2 charging for EVs is rated usually at 240 volts.

• This level of charging requires additional hardware.

• Some EV manufacturers provide Level 2 home charger installation services.

• A Level 2 charger takes about 6 to 8 hours to recharge EVs from 0 to 100 per cent based on its battery capacity.

• While Level 2 charging is efficient, it adds the cost of the hardware to the charging expense.

Level 3 EV charging

• Level 3 chargers typically charge at a rate of 480 volts.

• It requires only 1 hour or less to charge an EV from 0 to 80 per cent.
