The present invention provides a battery thermal management apparatus and a power battery, and relates to the technical field of batteries. The battery thermal management apparatus is used for a battery module including a plurality of monomer batteries, and comprises: battery fixation devices, wherein the battery fixation devices are used for fixing the monomer batteries and are respectively provided with a chamber for accommodating a heat storage material; at least a closed detection pipeline communicated to the chamber of the battery fixation device, wherein the closed detection pipeline is filled with a predetermined amount of gas when the chamber is filled with the heat storage material; and pressure sensors used for detecting the pressure of the gas in the closed detection pipeline and generating an alarm signal when the detected gas pressure is less than a preset value. According to the present invention, by converting the leakage condition into the pressure change of the gas in the closed detection pipe, the detection sensitivity is high, and the little leakage of the battery fixation device can be timely detected; and the whole battery thermal management apparatus has the simple structure, and the working safety of the battery module can be ensured.
Description
technical field [0001] The present invention relates to the technical field of batteries, in particular to a battery heat management device and a power battery. Background technique [0002] Batteries as an energy source can provide energy for other devices, such as electric vehicles that use batteries as energy sources. The cells are fixed into groups by some external structure to form a battery pack. At the same time, the heat dissipation or heating of the battery is realized through some structures such as pipes and cavities. If the substances in these external structures leak, it will have a serious impact on the safety of the battery, affect the normal operation of the battery, and even cause dangers such as short circuit, explosion, and combustion of the battery. Contents of the invention [0003] In view of this, the present invention provides a battery heat management device, which can monitor the leakage of the battery module. [0004] The technical scheme prov...
