Abstract

The invention relates to the technical field of energy systems, and discloses a distributive battery pack power supplying system. The distributive battery pack power supplying system comprises N firstpower batteries are connected to a first high-voltage box; N driving controllers corresponding to the high-voltage box are powered by the first high-voltage box; N second power batteries are connected to a second high-voltage box, and N driving controller corresponding to the second high-voltage box are powered by the second high-voltage box; the N first power batteries are in one-to-one-correspondence to the N driving controllers, and the N first power batteries separately directly power the corresponding driving controllers; he N second power batteries are in one-to-one-correspondence to the N driving controllers, and the N second power batteries separately directly power the corresponding driving controllers; the N first power batteries and the N second power batteries are connected toa CAN bus through a battery management system; and the driving controllers are connected to the CAN bus. By adopting the power supplying arrangement mode, reliability of the power supplying system inan energy car is improved; repairing is convenient and flexible; and the space utilization rate is great.

Description

technical field [0001] The invention relates to the technical field of energy systems, in particular to a distributed battery pack power supply system. Background technique [0002] With the development of new energy vehicles, the power supply of new energy vehicles has become one of the main factors restricting the development of new energy vehicles. The power supply of new energy vehicles mainly has low storable electric energy, short battery life, high battery replacement cost, and low battery reliability. In addition, many special vehicles are increasingly powered by electric energy. However, special vehicles have higher requirements on the reliability of the power supply system for the power system, and the design of the power supply system needs to stand the test. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a distributed battery pack power supply system for the above-mentioned problem of low reliabili...
