Diesel or gasoline engine cold cranking is a serious problem for different vehicle operation in northern countries. The engine starting torque is usually provided by an on-board electrochemical battery represented by a lead-acid unit. Modern energy storage devices, such as supercapacitors (SCs), lithium-ion, nickel-cadmium (NiCd) and nickel-metal hydride (NiMH) batteries react differently on low temperatures. Moreover, capacity losses also occur. Considering wide applications of such storage devices in electrical vehicles, their behaviour at low temperatures is of interest. Physical simulation of storage battery cold cranking was carried out using a climate chamber. Lithium-ion, NiCd, NiMH and lead-acid batteries were tested individually and paired with a SC unit to generate a power impulse for engine cranking. A number of experiments (up to five) for each type of storage devices were taken. The best performance results both for direct and hybrid cranking simulation were showed by LiFePO4-based and Ni-Cd batteries. The SC module itself showed the best performance, but its specific energy capacity cost is too high to have a large battery system based on SCs only. In this case a combined storage could give enough power to fulfill cranking demands.
