Abstract

The invention discloses a cooling and fire-fighting hybrid system for energy storage devices. The system comprises a box body, a plurality of energy storage devices are arranged in the box body, and cooling passages are arranged on the energy storage devices; a cooling circulation loop comprises a plurality of cooling branches communicated with the cooling passages, and is sequentially connected with a compressor, a condenser, a liquid storage tank, a throttle valve and a first switch valve used for controlling the on-off of the cooling circulation loop, and a flame-retardant refrigerant is stored in the liquid storage tank. The box body is internally provided with at least one spraying branch, the spraying branch is arranged above the energy storage devices and is communicated with the cooling circulation loop, and the spraying branch is provided with a plurality of spray heads and a second switch valve used for controlling the on-off of the spraying branch. The cooling and fire-fighting hybrid system further comprises a first fire extinguishing branch communicated with the cooling circulation loop, the other end of the first fire extinguishing branch is connected with a fire extinguishing agent tank, the first fire extinguishing branch is provided with a third switch valve used for controlling the on-off of the first fire extinguishing branch, and a temperature sensor is arranged in the box body.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a cooling and fire-fighting mixing system for an energy storage device and a control method thereof. Background technique [0002] The energy storage device has the advantages of convenient installation, small footprint, easy modular expansion, and strong environmental adaptability. It can be used in peak shaving energy storage, frequency modulation energy storage, photovoltaic power generation energy storage, wind power energy storage and other occasions. However, the energy storage device has a large number of batteries placed in a limited space, and the batteries will release heat during operation. If the heat is not dissipated in time, the heat will accumulate in the energy storage device, causing the temperature inside the device to rise continuously. Excessive temperature has a great impact on all aspects of battery performance, ranging from affecting battery performance ...
