A system for providing electrical power to a vehicle comprises a rechargeable electric battery pack 20 having two battery pack sections 100, 200. A control unit is coupled to the rechargeable battery pack sections. The rechargeable electric battery pack is connected to an electric motor for propulsion of the vehicle. Each battery pack section of the battery pack comprises a plurality of rechargeable electric storage cells and two connectable terminals 101, 102, 201, 202. The control unit is configured automatically to switch the power supply for a first electric appliance 50 from the first battery pack to the second battery pack, and to automatically switch the power supply for a second electric appliance 60 from the second battery pack to the first battery pack. The power supply for the appliances may be switched between the batteries in dependence on at least one performance variable of the battery pack sections, the performance variable including state of charge, state of health, temperature or voltage of the battery packs, or cells thereof. |
