Document Type and Number:
WIPO Patent Application WO/2024/060124
Kind Code:
A1
Abstract:
The present application relates to an overvoltage protection method, an apparatus, a computer device and a storage medium, which are applied to a high-voltage cascaded energy storage system, the high-voltage cascaded energy storage system comprising power units and energy storage units. The method comprises: acquiring a first voltage of a bus side of a high-voltage cascaded energy storage system; then according to the first voltage and a preset threshold, determining whether the high-voltage cascaded energy storage system has generated an overvoltage; and therefore, when the high-voltage cascaded energy storage system has generated an overvoltage, disconnecting a pathway between power units and energy storage units. The method can perform overvoltage protection on high-voltage cascaded energy storage systems.
