Embodiment Construction
[0022] In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.
[0023] In one embodiment, see figure 1 , to provide a battery control device for controlling the battery 20 . The battery 20 may include more than two cells. The installation method of the battery cells in the battery 20 is not unique. In this embodiment, the battery 20 includes more than two battery core layers arranged in layers, and the battery core layer includes more than two battery cells, each of which is connected in series or in parallel. The cell layer also includes a first cell support and a second cell support. The first cell support and the second cell s...

The invention relates to a battery control device and a battery system, the battery control device comprises a battery management system, an active equalization system and a selection device, one side of the battery management system is connected with the output side of the selection device, and the other side is connected with a battery; the second input side of the selection device is connected with the first output side of the active equalization system, the first input side of the active equalization system is used for being connected with charging equipment and performing charging equalization on battery cells in the battery, the second input side of the active equalization system is connected with the battery management system, and the second output side of the active equalization system is used for being connected with the battery; the selection device transmits the electric energy from the active equalization system to the battery management system when receiving the electric energy from the active equalization system. The condition that the battery is charged and discharged at the same time when the active equalization system works is avoided, unnecessary electric quantity waste can be avoided, the equalization efficiency is improved, and the use is reliable.
Description
technical field [0001] The present application relates to the field of battery technology, and in particular, to a battery control device and a battery system. Background technique [0002] As the world's oil resources become more and more scarce, it is necessary to find a new type of energy to gradually replace petroleum and fossil energy. As the hottest alternative energy, lithium-ion batteries have rapidly penetrated into all walks of life. However, with the rapid promotion and application of lithium-ion batteries, some problems of lithium-ion batteries have also been found. For example, the battery pack composed of hundreds of lithium-ion cells has the problem of inconsistent cells. The longer the use time, the more consistent The worse it will be, which will seriously affect the life of the battery pack. [0003] In order to solve the problem of inconsistent battery cells at the battery pack level, the traditional method of battery power balancing is to connect a resis...
