Abstract

The invention discloses an electric quantity control method and device of energy storage equipment and the energy storage equipment, the energy storage equipment comprises a battery module and an adjusting module, and the method comprises the steps of: when a power supply end normally supplies power, obtaining the current electric quantity of the battery module; judging whether the current electric quantity reaches a preset electric quantity threshold value or not; judging whether the load is in a power utilization state or not; and if the current electric quantity reaches the electric quantity threshold value and the load is in a power utilization state, adjusting the output voltage of the adjusting module, so that the battery current of the battery module is reduced to a first set range, and the electric quantity of the battery module is maintained in a preset electric quantity range. The electric quantity of the battery module of the energy storage equipment can be maintained at the preset electric quantity threshold value, the service life of the energy storage equipment can be prolonged, overcharge can be effectively prevented, and fire accidents are avoided.

Description

technical field [0001] The present application relates to the technical field of power supply control, and in particular to a power control method and device for an energy storage device and an energy storage device. Background technique [0002] When existing energy storage devices are used as uninterruptible power supplies, the battery packs in the energy storage devices are often kept fully charged. However, the battery pack is in high power for a long time, which has a certain impact on the life of the battery, and the battery is generally prone to fire accidents when the battery is about to be fully charged, posing a safety hazard. Contents of the invention [0003] In view of the above problems, the present application proposes a power control method and device for an energy storage device, and an energy storage device. [0004] This application proposes a power control method for an energy storage device, the energy storage device includes a battery module and an a...
