The invention relates to the technical field of power electronics and discloses a heating circuit, an aluminum substrate with the heating circuit, a battery pack and a solar battery. The heating circuit includes a heating branch and a voltage stabilizing branch. The voltage stabilizing branch is used for receiving a heating start voltage sent by a solar panel and sending a start signal to the heating branch. The heating branch is used for initiating the heating of the solar panel according to the activation signal. The activation signal of the heating branch is determined by a maximum power point voltage of the solar panel. By using the circuit of the invention, the heating function can be achieved by using a simple device, the heating circuit is suitable for the solar battery, and therefore, the heating circuit can work near a maximum power point of the solar panel. The utilization of limited solar energy is maximized to realize the heating of the battery with a minimum cost.
Description
technical field [0001] The invention relates to the technical field of power electronics, in particular to a heating circuit, an aluminum substrate with the circuit, a battery pack and a solar cell. Background technique [0002] At present, rechargeable batteries need to be charged within a preset temperature threshold range, for example, the battery charging temperature is required to be above 0 degrees or 10 degrees. Depending on the type of rechargeable battery, the temperature threshold required for charging is different. Therefore, it is necessary to bring the temperature of the battery to a predetermined temperature in order to achieve the best charging state of the battery. There are various approaches to heating circuits for multi-battery charging, but for heating rechargeable batteries used in solar panels, there are special requirements that need to track the solar maximum power point. [0003] A positive temperature coefficient (Positive Temperature Coefficient,...
