Description

technical field [0001] The invention relates to the field of electronics, in particular to a lithium battery heating mechanism in a low-temperature environment. Background technique [0002] In winter, in the north or in European and American countries, the ambient temperature is usually below -20°C. Under such environmental conditions, it is a headache to start a car with a lithium battery. However, due to the inherent characteristics of lithium battery materials, it has very strict requirements on the operating environment temperature. At present, it is difficult to achieve normal high-current start-up and discharge at both high and low temperatures. The actual discharge performance of lithium batteries at low temperatures is far lower than that at room temperature, and their performance decreases as the temperature drops. Generally, at -20°C, the discharge capacity is only 10%-20% of that at room temperature, and at -30°C, the discharge capacity is only about 2%. What's...
