Abstract
This application relates to a control method, apparatus, controller, system, medium, and product for an energy storage submodule. The method includes: isolating the power module from the battery module in the target energy storage submodule upon detecting a power module fault; and controlling the target energy storage submodule to enter a bypass state upon successful isolation of the power module and battery module. This method reduces the shoot-through risk of the battery module in the energy storage submodule and improves the reliability of the battery module.
