AI Technical Summary

Technical Problem

Existing technologies are unable to effectively maintain temperature balance in battery energy storage cabinets, especially the heat dissipation problem of the central battery, which leads to differences in performance parameters of each single battery in the battery pack, affecting overall performance and efficiency.

Method used

Liquid cooling is combined with a PLC controller and temperature control device. The battery surface temperature is monitored by a temperature meter, and the liquid flow rate in the pipeline and the connection area of ​​the open slot are adjusted. In combination with the insulation component and electromagnetic block, the battery temperature is finely adjusted to ensure temperature balance, and heating or insulation is performed when necessary.

Benefits of technology

It achieves fine regulation of the temperature inside the battery cabinet, avoids local overheating or overcooling, improves battery charging and discharging efficiency, reduces energy loss, and improves the overall energy efficiency of the energy storage system.

Abstract

The invention relates to the technical field of battery temperature control, in particular to an energy storage battery temperature control device which comprises an energy storage battery cabinet body, a partition plate is fixed in the energy storage battery cabinet body and divides the energy storage battery cabinet body into a battery storage cavity and a temperature control device storage cavity, a PLC is fixed in the battery storage cavity, and a temperature control device is fixed in the temperature control device storage cavity. And a plurality of battery storage mechanisms are arranged below the PLC. The temperature measuring device monitors the temperature of the battery storage shell at each position and transmits a signal to the PLC, and the PLC adjusts the current intensity of the second electric telescopic rod according to the temperature, so that the communication area of the opening groove and the arc-shaped groove is changed, the flow speed of cold water in the pipeline is increased or reduced in a disguised manner, and the cooling efficiency is improved. The heat dissipation effect is matched with the temperature of the batteries, the temperature balance of the batteries is ensured, the temperature among the batteries can be finely adjusted, the condition of temperature unbalance in the energy storage battery cabinet is avoided, and the problem that the temperature of the middle batteries is too high is avoided.
