Abstract

The present application relates to a high-voltage direct-mount energy storage system, a control method for an energy storage apparatus, and a control apparatus for an energy storage apparatus. The high-voltage direct-mount energy storage system may include: a clamping circuit; an energy storage apparatus, including a first energy storage main line, at least two energy storage sub-modules connected to the first energy storage main line, at least one dielectric branch, a first node disposed on the first energy storage main line, and a first grounding circuit connected to the first node, with a resistance value of the first grounding circuit being less than a preset resistance threshold; and a control apparatus, configured to control target engaged energy storage sub-modules on the two sides of the first node to be in a connected state based on an expected voltage of the energy storage apparatus and measured voltages of at least two energy storage sub-modules connected to the first energy storage main line. Embodiments of the present application can improve the stability of the voltage at the two ends of the energy storage apparatus, thereby facilitating improvement of operational reliability of components within the energy storage apparatus.
