The invention relates to an integrated power distribution system for an extended-range electric cold-chain logistics vehicle and the logistics vehicle. The integrated power distribution system comprises a box body, a low-voltage battery pack and a high-voltage battery pack, and a vehicle-mounted charger is arranged in the box body; the vehicle-mounted charger comprises a low-voltage transformation module and a high-voltage transformation module, the low-voltage transformation module is used for being connected with a low-voltage battery pack, and the high-voltage transformation module is used for being connected with a high-voltage battery pack; the external power supply outputs electric quantity to the low-voltage battery pack through the low-voltage transformation module and outputs electric quantity to the high-voltage battery pack through the high-voltage transformation module; the high-voltage battery pack is used for supplying power to vehicle high-voltage equipment, and the low-voltage battery pack is used for supplying power to vehicle low-voltage and the low-voltage battery pack and the high-voltage battery pack are supplied with power at one time through the vehicle-mounted charger arranged in the box body, so that the redundancy and reliability of the system are improved, and the use is convenient.
Description
technical field [0001] The invention relates to the technical field of cold chain logistics vehicles, in particular to an integrated power distribution system of an extended-range electric cold chain logistics vehicle and a logistics vehicle. Background technique [0002] The extended-range electric cold chain logistics vehicle is mainly used to deliver seafood, frozen food and other items that need to be stored at low temperature and some of them have shape requirements. The power distribution systems of existing extended-range electric cold chain logistics vehicles are separated from each other. The high-voltage battery pack belongs to one system, and the low-voltage battery pack belongs to another system. When the external battery is being charged, it needs to be charged separately to fully charge the high-voltage battery pack and the low-voltage battery pack. The high-voltage power supply provided for the cold chain scenario cannot ensure that the cold machine continues ...
