The invention relates to a lithium ion battery heating device, which belongs to the technical field of lithium ion batteries. The lithium ion battery heating device comprises an upper box body and a lower box body; the upper box body and the lower box body are buckled and connected in a covering manner; a lithium battery module, a control panel and heating film plates are arranged in the lower boxbody; a storage groove and a clamping groove are formed in the lower box body; heating film plates are connected to the two sides of the lithium battery module; the lithium battery module and the heating film plates are all fixed in the storage groove of the lower box body; the control panel is fixed in the clamping groove of the lower box body; an open slot is formed in one side of the surface of the upper box body; a charger is arranged in the open slot of the upper box body; the charger is respectively connected with the lithium battery module and the heating film plate; the charger is connected with the control panel through a CAN bus. The lithium battery can be effectively heated in the low-temperature environment, the battery charging problem in the low-temperature environment is ensured, the charging efficiency of the battery is improved, and the problem that the lithium battery is difficult to charge in the low-temperature use environment is solved.
Description
technical field [0001] The invention relates to a lithium-ion battery heating device, which belongs to the technical field of lithium-ion batteries. Background technique [0002] With the decrease of temperature, the discharge performance of lithium batteries is significantly reduced, the discharge platform is significantly reduced, and the discharge capacity is significantly reduced. When the temperature drops to -30°C, the discharge capacity of the battery is 87.0% of the discharge capacity at room temperature. If it is used in a low temperature environment for a long time, or in an ultra-low temperature environment of -40°C, the power supply will be "frozen" and cause permanent damage. Therefore, thermal management of lithium batteries is particularly necessary. The purpose of electric heating is to improve the activity of the positive and negative electrodes of the lithium battery, and the operating temperature of the battery must reach a reasonable range of use.
