Description

TECHNICAL FIELD

[0002] With the wide promotion and application of energy storage power supplies, more and more users begin to experience the convenience brought by them, but at the same time, some use problems in extreme environments have gradually emerged. In particular, in a low-temperature environment with a temperature lower than minus 20 degrees Celsius, the positive and negative electrode materials of the energy storage power supply are less active, and the conductivity of the electrolyte is limited, resulting in a significant decrease in battery capacity, a shortened service life, and even a failure to work normally in severe cases, which greatly affects the user experience.

[0003] In order to solve the above problems, some manufacturers have developed energy storage power supplies with heating function to maintain the temperature of the energy storage power supply between 20℃-55℃ in a low-temperature environment, so as to ensure that the energy storage power supply can maintain stable and normal operation. However, since such a device controls the heating element to frequently heat the power supply assembly of the energy storage power supply through the control panel, the failure and damage rate of the heating element is relatively high, and it needs to be frequently maintained and replaced. However, after the heating element is installed on the power supply assembly, it is usually electrically connected to the control panel by welding, which causes many inconveniences for the user when maintaining and replacing the heating element. Not only special tools are needed to separate the heating element from the control panel, but also the new heating element needs to be re-welded to the control panel when it is installed, which is a complicated process, greatly increasing the difficulty of installing and dismounting the heating element, and thus increasing the difficulty of maintaining the energy storage power supply, and the user experience is also affected.

The first collection control plate 110 is used for being fixed on the power supply assembly 200, and the first collection control plate 110 is used for being electrically connected with the power supply control assembly 300 of the energy storage power supply 10. The heating element 120 is used for being detachably installed on the power supply assembly 200, and the heating element 120 is used for heating the power supply assembly 200, so that the energy storage power supply 10 can maintain stable and normal work in a low-temperature environment. The first collection control plate 110 is provided with a female socket 111, and the heating element 120 is provided with a female plug (not shown in the figure) which is oppositely arranged with the female socket 111. The female plug is plugged into the female socket 111, so that the first collection control plate 110 is electrically connected with the heating element 120. Therefore, the user only needs to pull the female socket 111 away from the female plug, so as to detach and separate the heating element 120 from the first collection control plate 110. After replacing the new heating element 120, the user plugs the female plug into the female socket 111, so as to firmly electrically connect the heating element 120 with the first collection control plate 110. This greatly reduces the installation and detachment difficulty of the heating element 120.

When the heating element 120 needs to be replaced due to failure or damage, the user only needs to pull the female socket 111 away from the female plug, so as to separate the heating element 120 from the first collection control plate 110. Then, the heating element 120 is detached from the power supply assembly 200. Then, the new heating element 120 is installed at a preset position of the power supply assembly 200. Finally, the user only needs to plug the female plug of the new heating element 120 into the female socket 111 of the first collection control plate 110, so as to firmly electrically connect the heating element 120 with the first collection control plate 110.
