Problems solved by technology

Especially for high-power electrical devices such as pre-charging resistors, relays, and MOS tubes, a large amount of heat may be generated under extreme working conditions (such as switching relays multiple times in a short period of time in a high-temperature environment, pre-charging resistors lead to instantaneous temperature rise), if effective cooling measures cannot be taken to dissipate this part of the heat in time, the temperature inside the electrical device will rise rapidly, even exceeding the normal operating temperature of the electrical device
In this way, it will accelerate the aging of the electrical device and reduce its service life

Abstract

A battery pack comprises a housing, a battery core and a BMS, wherein the battery core and the BMS are arranged in the housing, and the BMS is electrically connected with the battery core. The batterypack further comprises a first radiator arranged in the housing, a second radiator arranged outside the housing and a semiconductor chilling plate located between the first radiator and the second radiator. The semiconductor chilling plate comprises a first end connected with the first radiator and a second end connected with the second radiator. The BMS is further electrically connected with thesemiconductor chilling plate, and the BMS is used for controlling the semiconductor chilling plate to conduct refrigeration at the first end and conduct heating at the second end. The invention further provides a heat dissipation method of the battery pack.
