Description

technical field [0001] The invention relates to an ion capacitor starting power supply system and a starting power supply device designed for the system. Background technique [0002] The starting power supply is an energy storage device necessary for electric starting the engine. Taking a diesel engine as an example, a diesel generator set is mainly composed of an engine and a generator. Before the unit is started, the starting power supplies power for the engine, ECU, control box and other DC appliances; after the unit is started, the starting power supply can be used as an auxiliary power supply device. It can store the excess electric energy of small generators, so it plays an important role in the generator set. At present, most diesel generator sets use lead-acid batteries as the starting power supply. Mature technology and low cost make them occupy a large share in the starting power supply market of generator sets. However, lead-acid batteries have a short lifespan...
