A method of managing a capacitor module of a vehicle, comprising: determining 330, whilst an engine of the vehicle is non-operational, when state of charge of the capacitor module is less than a minimum state of charge for engine cranking, charging 350 the capacitor module from a battery module of the vehicle, such that the state of charge of the capacitor module is at least the minimum state of charge for engine cranking, and providing 370 electrical power solely from the capacitor module to a starter motor associated with the engine to crank the engine for starting. Preferably the state of charge of the capacitor module is determined based on an output voltage of the capacitor module. Preferably the minimum state of charge is based on either the temperature of the capacitor module, a temperature of the engine, or an ambient temperature. The method may be performed when the temperature of the capacitor module, engine, or ambient temperature, is less than a predetermined value. Preferably the capacitor module comprises one or more supercapacitors or ultracapacitors, and the battery is Li-ion.
