Abstract
The invention discloses a temperature control system for an energy storage battery container utilizing groundwater, which comprises an energy storage battery container, heat exchange chambers arranged on the outer walls around the energy storage battery container, and a water storage tank arranged under the energy storage battery container. The water tank is connected with external groundwater through pipes; the water inlet and outlet pipes of the energy storage battery container and the water inlet and outlet pipes of the heat exchange room are all connected with the water storage tank; multiple energy storage battery stacks are arranged in the energy storage battery container, and each energy storage battery The battery stack is formed into a polygon by multiple energy storage battery groups; each energy storage battery group is composed of multiple lithium battery cells, and a water cooling plate is arranged between adjacent lithium battery cells. The system of the present invention uses groundwater as a cold source to cool down the battery when it is working. Before the battery is started in winter, the groundwater is used as a heat source to preheat the battery stack to avoid damage to the battery caused by low-temperature start-up. The system of the present invention uses groundwater as a The heat exchange source greatly reduces the energy consumption of the system, avoids the high energy consumption problem caused by the use of central air conditioning, and improves the energy utilization rate.
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...
