[0045] At present, from the perspective of market development, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0046] The battery includes a battery cell and a thermal management component. The thermal management component is used to adjust the temperature of the battery cell so that the battery can work at a suitable temperature to improve the stability of the battery. A heat exchange medium is input into the thermal management component. The heat exchange medium flows in the thermal management component and exchanges heat with the battery cell to adjust the temperature of the battery cell. For example: when the temperature of the battery cell is high, a heat exchange medium with a lower temperature is injected into the thermal management component. The heat exchange medium absorbs the heat generated by the battery cell and reduces the temperature of the battery cell; when the temperature of the battery cell is low, a heat exchange medium with a higher temperature is injected into the thermal management component. The heat exchange medium transfers the heat to the battery cell, thereby increasing the temperature of the battery cell. The thermal management component can make the battery cell work at a suitable temperature and improve the stability of the battery.

[0047] However, when there are impurities in the heat exchange medium, the impurities are likely to block the heat exchange channels of the thermal management components, resulting in a decrease in the flow rate of the heat exchange medium, affecting the thermal management effect of the thermal management components and affecting the stability of the battery.

The heat exchange medium flows into the channel from the inlet, and when impurities pass through the plugging assembly, the plugging assembly can filter the impurities in the heat exchange medium. The filtered heat exchange medium flows to the heat exchange channel of the thermal management component through the outlet, reducing the risk of impurities blocking the heat exchange channel, increasing the flow rate of the heat exchange medium in the heat exchange flow channel, improving the thermal management effect of the thermal management component, and improving the stability of the battery.
