Abstract

The invention discloses a battery thermal management device of a new energy vehicle. The device comprises a casing body (5), at least one battery cell (1) arranged in the casing body (5), and heat dissipating plates (2) attached to both sides of each battery cell (1). Each heat dissipating plate (2) comprises a phase change material heat dissipating plate and a heat pipe for dissipating heat of the phase change material heat dissipating plate. Each heat pipe comprises an evaporation section and a condensation section. Each evaporation section is inserted inside a phase change material heat dissipating plate, and each condensation section is located on the outer side of the phase change material heat dissipating plate. Each heat pipe further comprises a liquid cooling plate (4) in contact with the condensation section. The battery thermal management device effectively solves the problem of poor heat dissipation of a new energy battery and poor temperature uniformity of the battery. Theinvention further discloses the new energy vehicle including the battery thermal management device, and the new energy vehicle has the above-mentioned beneficial effects.

Description

technical field [0001] The invention relates to the technical field of new energy vehicle batteries, in particular to a battery thermal management device. In addition, the present invention also relates to a new energy vehicle comprising the above battery thermal management device. Background technique [0002] Electric vehicles all use power batteries as their power. Electric vehicles convert electrical energy into mechanical energy through controllers, motors and other components to drive electric vehicles to run. [0003] The power battery of an existing electric vehicle is generally composed of a square lithium battery or a cylindrical lithium battery through series or parallel connection to form a high-power, large-capacity lithium battery pack. The rapid development of new energy vehicles and high-power fast charging can greatly reduce the charging time of electric vehicles. Relatively speaking, high-rate charging will cause the battery pack temperature of electric v...
