Energy storage battery container temperature control system utilizing underground water

Abstract

The invention discloses an energy storage battery container temperature control system utilizing underground water, which comprises an energy storage battery container, a heat exchange chamber arranged on the outer side wall of the periphery of the energy storage battery container and a water storage tank arranged below the energy storage battery container, and the water storage tank is communicated with the external underground water through a pipeline; a water inlet-outlet pipe of the energy storage battery container and a water inlet-outlet pipe of the heat exchange chamber are communicatedwith the water storage tank; a plurality of energy storage battery stacks are arranged in the energy storage battery container, and each energy storage battery stack is a polygon defined by a plurality of energy storage battery packs; and each energy storage battery pack is composed of a plurality of single lithium batteries, and a water cooling plate is arranged between every two adjacent singlelithium batteries. According to the system, when the battery works, underground water is used as a cold source to cool the battery, and before the battery is started in winter, the underground wateris used as a heat source to preheat the battery stack, so that the damage to the battery caused by low-temperature starting is avoided,the system takes underground water as a heat exchange source, theenergy consumption of the system is greatly reduced, the problem of high energy consumption caused by using a central air conditioner is avoided, and the energy utilization rate is increased.

Description

technical field [0001] The invention relates to a temperature control system for an energy storage battery container utilizing underground water. Background technique [0002] In recent years, with the depletion of non-renewable energy sources and the continuous aggravation of environmental pressure, people have turned more and more attention to renewable energy sources (wind energy, solar energy, tidal energy, etc.). As a common energy storage device for solar power generation and wind power generation equipment, the energy storage battery container stands out among many energy storage devices due to its characteristics of convenient installation, small footprint and flexible movement. However, from the perspective of energy saving and environmental protection, energy storage batteries are mostly decommissioned power batteries. Compared with the unused power battery, its battery performance has dropped considerably. Especially in high temperature conditions, violent react...
