Description

technical field [0001] The invention relates to a vehicle-mounted power supply device of a hybrid electric vehicle. Background technique [0002] Most of the current on-board power supply devices of hybrid electric vehicles are composed of a single battery. With the development of science and technology in recent years, battery technology still cannot solve the interaction between specific energy / energy density and specific power / power density. At the same time, because the battery uses chemical methods to store energy, it is difficult to charge and amplify the battery instantaneously, resulting in low efficiency of the power system and poor recovery of braking energy, which is unfavorable to the economy of the vehicle. Contents of the invention [0003] The object of the present invention is to provide a vehicle-mounted composite power supply device for a hybrid electric vehicle with an improved structure in order to overcome the disadvantages of low specific power of the...
