Short answer
A Level 2 EV charger usually needs a dedicated 240-volt circuit of 40-60 amps. Whether your panel can handle it depends on service size (often 150-200 amps in newer homes), current loads and available breaker space. An electrician performs a load calculation and may suggest load management instead of a costly service upgrade.
Panel capacity
Many 2000s homes have 200-amp service; older homes may have 100-150 amps.
Load calculation
Accounts for AC, water heater, range, dryer and other loads.
