Abstract
At low temperatures, lithium-ion batteries have problems such as difficulty in discharging and decaying of discharge capacity. The internal heating method has become the first choice for preheating lithium-ion batteries. However, most of the existing internal heating devices are wired heating, which has disadvantages such as easy leakage, contact loss, and mismatch of plugs and sockets. In order to solve this problem, this paper proposes an AC heating device for automobile interior based on wireless power transmission. The lithium-ion battery is heated while the primary and secondary sides are separated by an air gap, and the heating speed can be adjusted online by controlling the output voltage. This paper analyzes the heating topology, and establishes a low-temperature heating experiment platform for lithium-ion batteries, which proves the feasibility and effectiveness of the scheme. Experimental result shows that the heating device only used 1100s to increase the lithium-ion battery from -15°C to 5°C.
