To charge two EVs at home on Long Island you generally need at least 200-amp service, and often load management so both chargers share capacity instead of running full-speed at once. If you want both vehicles charging at maximum amperage simultaneously, you may need a 320- or 400-amp service. The right answer depends on your existing loads and how fast you actually need to charge — most two-car households charge overnight and never notice load sharing. We run a load calculation and recommend the most cost-effective path, whether that's smart load management on your existing panel or a service upgrade.
Why it matters for Long Island homeowners
Two Level 2 chargers can demand 80–96 amps of continuous load combined — more than the entire service of an older 100-amp home in Selden or Farmingville. Sizing this correctly prevents tripping and overheating, and choosing load management over a full 400-amp upgrade can save thousands while still charging both cars overnight.
Load management vs. bigger service
Smart EV load management lets two chargers share one circuit, automatically throttling so you never exceed capacity. For most two-EV households this is cheaper than a 400-amp upgrade and charges both cars fully by morning. Heavy daytime charging or a future heat pump may justify the larger service.
Frequently Asked Questions
Can I charge two EVs on a 200-amp panel?
Usually yes, with load management so the chargers share capacity. Without it, two full-speed Level 2 chargers may exceed a 200A service combined with existing loads.
Do I need a 400-amp service for two EVs?
Only if you need both cars charging at maximum speed at the same time, or you have other heavy loads. Many two-EV homes do fine on 200A with smart load management.
