Embodiment Construction

[0067] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0068] As a key device connecting high-voltage energy storage devices and high-voltage power components, the high-voltage DC bus needs to charge and discharge the energy of the high-voltage DC bus during the process of high-voltage power-on and high-voltage power-off. In addition, in order to ensure the continuous power demand of low-voltage power components for low-voltage power, a unidirectional DC / DC power conversion module is usually used to take power from the high-voltage energy storage device to charge the low-voltage energy storage device to ensure that the low-volt...
