Embodiment Construction

[0052] At present, battery energy storage systems are more and more widely used in new energy, smart grid, energy-saving technology and other fields from power generation to power consumption. Improve the ability to connect renewable energy to the grid.

[0053]The energy storage container is an important part of the battery energy storage system. The power battery is greatly affected by the temperature. When the temperature of the lithium-ion power battery exceeds the safe use range of the battery and works in a high temperature environment for a long time, the battery itself will An irreversible reaction will occur, which will accelerate the decay of the battery cycle life and reduce the overall performance of the energy storage cabinet; when the temperature of the lithium-ion power battery reaches the ignition point of the internal materials of the battery, if the heat generated by the battery itself cannot be dissipated in time, the battery will be damaged. The phenomenon ...

Abstract

The invention provides a battery thermal management system and an energy storage container. The battery thermal management system comprises a control device, a cooling device and a temperature sensor.The temperature sensor is arranged on the battery module and is used for detecting the temperature of the battery module and sending a temperature signal to the control device. The cooling device comprises a refrigerator and an air channel, wherein the air outlet of the refrigerator is communicated with the air inlet of the air channel, and the air outlet of the air channel is arranged on the battery module; the control device is electrically connected with the temperature sensor and the refrigerator respectively; and the control device controls the working state of the refrigerator accordingto the temperature signal. The control device of the invention judges the temperature of the battery module according to the temperature signal, and then controls the refrigerator to work and generate cooling gas, the cooling gas is released to the battery module through an air duct, the battery module is effectively cooled and radiated, the cooling efficiency is high, the cooling requirements ofthe battery module are met, the battery is guaranteed to work effectively, and the service life of the energy storage container is prevented from being influenced by the relatively high temperature of the battery module.

Description

technical field [0001] The invention relates to the technical field of electrical technology, in particular to a battery thermal management system and an energy storage container. Background technique [0002] At present, battery energy storage systems are more and more widely used in new energy, smart grid, energy-saving technology and other fields. The energy storage container is an important part of the battery energy storage system, and the power battery is greatly affected by the temperature. If the temperature of the power battery is too high, the life of the energy storage container will be affected. Therefore, measures must be taken to cool down the power battery. [0003] The energy storage container includes a box body, a control cabinet arranged in the box body, and at least one energy storage cabinet. The energy storage cabinet includes a high-voltage box and at least one power battery module. The power battery module includes the power battery module and the b...
