Abstract
The invention discloses a battery module and a battery heat exchange method, wherein the battery module includes a battery pack, a first heat exchange device, a second heat exchange device and a control unit; The exchange part for heat exchange, the exchange part is attached to the battery pole covered by the battery pack; the second heat exchange device includes a box body, the battery pack is placed inside the box body, an air inlet is provided on one side of the box body, and the box body There is an air outlet on the other side of the box; the control unit is arranged on the outer wall of the box, and controls the exchange components for heat exchange, and controls the air inlet for air inflow and the air outlet for air outflow. By heating the battery pack with the liquid / phase The first heat exchange device for exchange and the second heat exchange device for wind heat exchange are combined to form a battery module, and the two heat exchange devices can be activated simultaneously or individually, which not only increases the effect of heat exchange efficiency, but also greatly saves energy.
Description
technical field [0001] The invention relates to the technical field of batteries, in particular to a battery module and a battery heat exchange method. Background technique [0002] With the rapid development of new energy vehicles, the market demand for power batteries widely used in vehicles is increasing. However, the power battery is very sensitive to temperature. Under inappropriate temperature conditions, it will cause damage to the battery and increase the ability of the battery to generate side reactions, which will reduce the performance of the battery and attenuate its life, and even cause thermal runaway, causing major safety risks. . For example, under low temperature conditions, especially below 0°C, charging the battery will form lithium branch gold on the surface of the anode, which will pierce the diaphragm and cause an internal short circuit. In severe cases, fire and explosion may occur; under high temperature conditions, such as high temperature At 35°C,...
