Installing two EV chargers at home has gotten complicated with all the panel capacity and load sharing questions flying around. As someone who’s helped households with multiple EVs navigate this situation, I learned everything there is to know about running two chargers from one home. Today, I’ll share it all with you.
Can You Do It?
Probably should have led with this section, honestly — yes, you can have two chargers, but your electrical panel needs adequate capacity. Two Level 2 chargers drawing full power simultaneously requires 80-100 amps. Many older homes can’t spare that much.
Solutions That Work
Load Sharing
That’s what makes load-sharing systems endearing to us multi-EV households — two chargers share available power intelligently. When both cars charge simultaneously, each gets half power. When only one charges, it gets full power.
Scheduled Charging
Program chargers to run at different times. One car charges 6pm-midnight, the other midnight-6am. Same circuit, same capacity, both cars fully charged by morning.
Panel Upgrade
If you want two full-power simultaneous chargers, you may need 200-amp or 400-amp service. Expensive, but provides maximum flexibility.
The Practical Answer
Most households don’t need simultaneous full-power charging. Scheduled charging or load sharing handles two EVs without expensive upgrades.
