Abstract

The invention provides a battery device, a control method, a control device and a battery system. The battery device comprises a battery component, cold storage equipment and a driving component, wherein the battery component comprises a battery body and a cold liquid tube set located at one side of the battery body; the cold storage equipment comprises a cold storage component and a cold end fluid distributer, and the cold storage component comprises a cold storage device and a permanent magnet structure; and the driving component is used for driving the permanent magnet structure and / or thecold storage device to move, so that the permanent magnet structure and the cold storage device move relative to each other. According to the battery device, a cold end outlet communicates with the cold liquid tube set in an on / off mode, that is, on / off of the cold end outlet and the cold liquid tube set can be controlled according to the actual situation, and therefore the situation that short-term temperature fluctuation is caused by direct conduction between magnetic refrigerating equipment and the battery component, and consequently the temperature uniformity of the battery component is affected is avoided. Moreover, in the battery device, the permanent magnet structure is adopted to provide a magnetic field; and compared with superconductive magnet and an electromagnet, the permanentmagnet structure is simple, low in cost and free of cooling.

Description

technical field [0001] The present application relates to the field of new energy power batteries, in particular, to a battery device, a control method, a control device, a storage medium, a processor and a battery system. Background technique [0002] With the development and popularization of new energy city buses, the energy density of power batteries is increasing year by year, and the amount of power batteries is also expanding year by year. People are constantly putting forward higher requirements for the cruising range of new energy vehicles. The accompanying problem is that the battery generates a lot of heat and temperature, which has an adverse effect on the battery's power and life. As the core component of electric vehicles, the use of power batteries is greatly affected by the ambient temperature, so a battery device is required to control the battery at a better working environment temperature. [0003] Traditional battery devices use vapor compression refrige...
