What EV Charger Do You Need for a 2025 Volvo EX40?
Forty-eight amps is the magic number for your Volvo. The onboard charger takes 48 amps of Level 2 current, translating to 35 miles of range per hour. You need a dedicated 48-amp EVSE to hit the 8.5 hour full charge time. Do not buy a smaller unit if you want maximum speed.
The numbers
| Maximum AC charging rate | 11.0 kW (48 A) |
|---|---|
| Charger size to buy | 48 A |
| Circuit breaker required | 60 A |
| Outlet / connection | hardwired (a 48 A EVSE must be hardwired -- no household receptacle is rated for it) |
| Charge port | J1772 |
| Full charge on Level 2 | about 8.5 hours |
| Range added per hour (Level 2) | about 35 miles |
| Full charge on a 120 V outlet | about 65 hours |
| Range added per hour (120 V) | about 4.5 miles |
| EPA rated range | 296 miles |
| Energy for a full charge | about 93.8 kWh at the wall |
Why 48 amps and not more
Your battery holds 93.8 kWh, so matching the 48-amp maximum capacity is the only way to refill the pack overnight. Feeding this car fewer amps means longer waits plugged into the wall. Pumping more amps into the vehicle does nothing because the onboard charger caps the intake at 11.0 kW. Stick to the 48-amp rating. It hits the sweet spot for daily replenishment without wasting money on oversized hardware.
What the install involves
Call an electrician to install a 60-amp breaker and heavy-gauge wiring. The 48-amp charger must be hardwired directly to the circuit because no standard household receptacle handles that load safely. Code prohibits plugs for continuous loads this large. Let the licensed pro handle the panel work and the final wall mount.

Common questions
- Can I use a regular wall outlet?
- Level 1 charging on a standard 120-volt household outlet takes 65 hours for a full tank and adds only 4.5 miles per hour. That speed works only for very low mileage drivers. Install a Level 2 setup for real convenience.
- What connector does the car use?
- This vehicle uses a J1772 connector. Many 2025 models ship with a NACS port and a J1772 adapter, so check your specific port before buying hardware. A standard J1772 home charger still works fine.
- Why does the EPA charge time differ?
- The EPA test estimates an 8.0 hour charge time yielding 37 miles per hour. Standard real world math at maximum Level 2 output shows 8.5 hours and 35 miles per hour. Testing protocols vary slightly from everyday use.
- Do I need a permit for the installation?
- Most local municipalities require an electrical permit for a 60-amp hardwired circuit. Your electrician usually pulls this permit as part of the job. Always check local building codes before starting.
