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

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.
Description
technical field [0001] The present application relates to the field of batteries, in particular to a battery pack and a heat dissipation method thereof. Background technique [0002] At present, with the rapid development of the new energy industry, battery applications are more extensive, such as providing electric energy for electric vehicles through power battery systems, which can reduce the use of non-renewable resources. [0003] During the use of the battery, the electrical devices on the battery management system (Battery Management System, BMS) will consume part of the power and convert it into heat. If the heat dissipation is not good, it will easily lead to continuous heat accumulation inside the electrical devices. Heat buildup continues inside electrical components. 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...
