Abstract

The operation of internal combustion, reciprocating engines in some automotive vehicles may be managed such that the engine operation is stopped each time the vehicle is brought to a stop, and then the engine is re-started when the operator presses the accelerator pedal to put the vehicle in motion. In some driving situations the engine of the vehicle may be stopped and re-started many times, which is a mode of engine operation for which the traditional 12 volt, lead-acid battery is not well suited. It is found that a six cell, lithium-ion battery combining LiFePO₄ as the active positive electrode material and Li₄Ti₅O₁₂ as the active negative electrode material, together with suitable separators and a suitable low freezing point electrolyte may be adapted to deliver starting power for repeated engine starting, despite short intervening charging periods.
