Abstract

The invention relates to a power battery cooling and heating integrated system, which comprises a cooling liquid tank, a circulating pump, a radiator and a battery pack heating and cooling integrated board, wherein the cooling liquid tank is connected with the circulating pump; the circulating pump is connected with the radiator; and one end of the battery pack heating and cooling integrated board is connected with the radiator and the other end of the battery pack heating and cooling integrated board is connected with the cooling liquid tank. The power battery cooling and heating integrated system has the advantages that one set of substrate is shared by a heating system and a cooling system, the power battery cooling and heating integrated system is long in service life, good in stability, good in heating and cooling effects, high in integration level, convenient to use and high in heat utilization rate, and the power is saved.

Description

technical field [0001] The invention relates to the field of new energy vehicle batteries, in particular to a power battery cooling and heating integrated system and the battery. Background technique [0002] The heating principle of the existing power battery heating system: start the water pump and the PTC heater, the coolant passes through the water pump, the PTC heater, the liquid cooling plate, and the coolant tank for circulation heating, and the heated coolant transfers heat to the water cooling plate, The liquid cold plate then transfers the heat to the power battery. [0003] This kind of heating system has the following disadvantages: During the heating process, it is necessary to heat the refrigerant tank, pipeline, PTC heater and the coolant in the PTC heater, and the whole system has a long circulating water path, and the heat dissipation pump must also work. It consumes a lot of useless heat, and the utilization rate of electric energy is low; especially when ...
