The invention provides a battery temperature control device. The battery temperature control device comprises an inner cavity, a shell, a temperature control unit and a control unit; the inner cavityis used for placing a battery; the shell is arranged on the outer side of the inner cavity in a sleeving way; a closed interlayer is arranged between the shell and the inner cavity; the interlayer isfilled with liquid metal; the temperature control unit comprises a heating assembly and a temperature sensor; the heating assembly is arranged in the interlayer and is used for heating the liquid metal; the temperature sensor is used for measuring the temperature of the liquid metal; and the heating assembly and the temperature sensor are electrically connected with the control unit. The interlayer between the inner cavity and the shell is filled with the liquid metal, the battery is placed in the inner cavity, and the temperature is transmitted to the inner cavity by utilizing the liquid metal, so on one hand, direct contact between the liquid metal and the battery is avoided, and on the other hand, temperature drift can be reduced rapidly and accurately; and besides, the power of the heating assembly is adjusted by the temperature sensor and the temperature of the inner cavity is maintained to be the battery optimal charging efficiency temperature for a long time, so that the charging efficiency of the battery is improved.
Description
technical field [0001] The invention relates to the technical field of battery energy storage, in particular to a battery temperature control device. Background technique [0002] Batteries, as a device that directly converts chemical energy into electrical energy, play an important role in the national economy and defense industry. In recent years, with the rapid development of Internet technology and the rapid development of electronic information technology, my country's battery industry has achieved unprecedented development, and my country has become the largest producer and consumer of the battery industry. At the same time, it also leads to the expansion and development of related industries. Taking lithium-ion battery as an example, as a new type of chemical power source, it has outstanding advantages such as high energy density, low self-discharge rate, good cycle performance, no memory, no pollution and high charge retention performance, etc. It is considered to ...
