Abstract

The invention discloses a liquid cooling plate with heating and temperature equalizing performance, which comprises a liquid cooling plate, one side of the liquid cooling plate is connected with a water inlet and a water outlet, a plurality of heating sheets are mounted on a liquid cooling plate flow channel at the bottom of the liquid cooling plate, a silica gel pad is arranged on the liquid cooling plate, and the upper side of the silica gel pad is connected with a battery module. The bottom side of the battery module adopts a plurality of heating pieces, the heating pieces are distributed at the bottom of the battery module, and the temperature of battery cooling liquid can be increased by controlling the on-off of the heating pieces, so that the purpose of heating is achieved; the aim of balancing the temperature of the battery module is fulfilled by controlling the on / off of one or more heating sheets; and the liquid cooling plate has a heating function, is simple in structure and low in cost, and can solve the problems of low-temperature heating and non-uniform temperature of the power battery.

Description

technical field [0001] The invention relates to the field of battery thermal management, and relates to a new type of liquid cold plate with heating and temperature uniformity performance, which is mainly used in the thermal management system of battery packs of new energy electric vehicles. Background technique [0002] When the power lithium-ion battery is in use, it needs to be at a suitable temperature to ensure its normal use. At a lower temperature, the chemical reaction activity of the battery decreases. During the charging process, lithium ions are extracted from the positive electrode and migrated into the negative electrode material through the electrolyte. The migration of lithium ions slows down. The lithium ions on the surface of the negative electrode have not been embedded in the negative electrode. It is reduced to metallic lithium and precipitated on the surface of the negative electrode to form lithium dendrites, which can easily cause safety accidents. Th...
