Land Rover
Reduced Charging Power / Derating
Charger and vehicle both indicate that charging is in progress, but the Land Rover vehicle's battery percentage does not increase or increases very slowly.

Possible Causes
Charger current limit set too low in Land Rover app, Dynamic load management limiting current due to household load, Overtemperature derating inside charger, Undersized supply wiring causing voltage drop
How to Fix / Troubleshooting
Safety warning: Do not increase current beyond the rating of the circuit and wiring.
- 1. Check current setting: In the Land Rover charger app, verify the maximum charging current. Increase it within the limits of your installation if set too low.
- 2. Review load management: If dynamic load management is enabled, check if other large loads (ovens, heat pumps) are active. Temporarily reduce other loads and see if charging current increases.
- 3. Monitor charger temperature: If the charger feels hot, it may be derating. Improve ventilation and consider reducing ambient temperature.
- 4. Verify supply capacity: Confirm that the circuit breaker and wiring are correctly sized for the charger's rated current. If undersized, consult an electrician to upgrade.
- 5. If power remains low despite settings: A technician should check internal current sensors and contactor for overheating or miscalibration.
