AI Technical Summary
Existing technologies cannot simultaneously meet the requirements for high reliability and low cost improvement of lithium batteries in low-temperature environments. The performance of lithium-ion batteries is affected at low temperatures, including reduced energy release capacity, reduced power, and reduced usable capacity.
An additional heating film is attached to the surface of the battery cell, and the heating state of the heating film is controlled by a temperature protector. The heating film directly heats the battery cell, and the temperature protector ensures that the battery cell temperature is within a suitable range to prevent overheating.
It enables normal charging and efficient operation of lithium batteries in low-temperature environments, reduces improvement costs, improves battery reliability and space utilization, and reduces failure rate.
