Abstract

The invention discloses a high-rate charging liquid-cooled battery box, comprising a hollow main box body (50) with an opening at the top; The top of the main box body (50) is covered with and connected with a box cover (10); The main box (50) is internally provided with a battery module, and the battery module comprises a plurality of battery modules (70). Each battery module (70) includes a plurality of battery cells arranged in parallel in the longitudinal direction; A liquid cooling plate (63) is respectively arranged on the front and rear sides of each battery module (70). The left and right sides of the battery module are respectively provided with a liquid cooling pipeline (61); The liquid cooling line (61) is in communication with the liquid cooling plate (63). The invention can effectively control the temperature rise of the lithium battery, thereby ensuring that the battery cell in the battery module is charged and discharged at a high rate, thereby ensuring the safety performance of the battery cell, remarkably reducing the use safety risk of the battery module, and ensuring the overall safety performance of the battery module.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a high-rate charging liquid-cooled battery box. Background technique [0002] At present, according to the new energy power system product standards for commercial vehicles issued by the country, the market urgently needs new energy power systems for commercial vehicles to meet the requirements of higher grouping rate, short charging time, wide temperature operation, and multi-region coverage. With the rapid development of the electric vehicle industry, the models of electric vehicle battery systems are becoming more and more diverse. Lithium-ion batteries take into account high energy density, high safety and good cycle life. [0003] However, taking the pure electric natural cooling system as an example, due to the inherent limitation of the chemical properties of lithium-ion batteries, under natural cooling conditions, high-rate charging and discharging may easily cause the ...
