Problems solved by technology
[0003] The inventors of the present application found in the process of research and practice that in the prior art, a heating film can be installed on the battery, and the temperature of the battery can be raised to the target temperature through the heating film, and the BMS single board can be heated by the heated battery. Baking prevents the battery and BMS single board from reaching the dew point, thereby avoiding the risk of short circuit caused by condensation. However, an additional heating film is required, which is too expensive. In addition, the heating of the battery through the heating film is from the outside to the inside. It will lead to uneven heating of the battery and BMS single board, and low heating efficiency

The invention provides a battery system and a power supply system. The battery system comprises a first battery pack and a battery management system; the battery management system is connected with the first battery pack; and the battery management system comprises a sampling control circuit and a battery heating circuit. The first battery pack and the battery management system can form a battery module, and the battery module can be applied to various battery application fields such as the communication field and power automobiles. The sampling control circuit can control the battery heating circuit to charge the first battery pack or control the first battery pack to discharge to the battery heating circuit based on the battery temperature of the first battery pack and the environmental parameters until the temperature of the first battery pack is higher than the dew point temperature of the first battery pack so as to realize battery condensation prevention. Based on the application, the first battery pack and the battery management system can be synchronously heated, so that the condensation short circuit risk is reduced, and the heating efficiency and the energy utilization rate are improved; and the cost is low, and the applicability is high.
Description
technical field [0001] The present application relates to the technical field of electronic power, in particular to a battery system and a power supply system. Background technique [0002] With the widespread use of batteries, when the temperature of the battery and the battery management system (BMS) board is lower than the ambient temperature, it is easy to condense on the battery and the board, and there will be a short circuit between the battery and the BMS board. phenomenon, which in turn leads to the risk of carbonization of the BMS veneer and battery fire. Therefore, how to prevent condensation on batteries and BMS boards is particularly important. [0003] The inventors of the present application found in the process of research and practice that in the prior art, a heating film can be installed on the battery, and the temperature of the battery can be raised to the target temperature through the heating film, and the BMS single board can be heated by the heated b...
