Description

Cooling and fire extinguishing device for power storage system

This invention relates to a cooling and fire extinguishing device for an electrical storage system, in particular to a cooling device that can deliver liquid through a pipeline connected to an electric energy supply unit.

With the evolution of the times, the energy density of energy storage units represented by lithium batteries has accelerated, which has solved the battery life problem that has plagued electric vehicles for nearly a century. Emerging electric vehicle brands represented by Tesla have risen, and traditional fuel vehicle manufacturers have also R&D and production of electric vehicles are being accelerated. At the same time, the construction of charging piles, power stations for electric vehicles, and fuel cell facilities, such as hydrogen refueling stations, is also accelerating.

With the development of battery energy storage units and concerns about rising mineral energy reserves and oil prices, major automobile manufacturers have begun to make attempts in the field of new energy vehicles, and the industry has gradually launched different pure electric vehicles and locomotives. , bicycles and other designs.

A pure electric vehicle, also known as a pure electric vehicle or a battery electric vehicle (BEV), refers to a vehicle that uses a battery to supply power to a motor, and the motor drives the vehicle, and the power of the battery is supplemented by an external power supply.

Pure electric vehicles do not emit exhaust gas themselves, so they will not pollute the air around the road. Electric motors have excellent low-speed and acceleration capabilities and energy efficiency. Therefore, pure electric vehicles can improve efficiency when applied to work vehicles that need to stop and go frequently (buses, garbage trucks and other vehicles with high torque requirements). When a fuel car is parked, the engine still needs to be idling to avoid stalling, so the fuel is wasted in vain, and unnecessary carbon emissions and pollution are generated. Energy consumption, and kinetic energy can be recovered to recharge the battery when braking or going downhill. While making full use of the energy, it will not generate waste heat from the brakes, and at the same time avoid the loss of parts, and do not require any maintenance. Even if it is a private electric car, In cities with heavy traffic, it also has the effect of reducing waste and controlling the environment.

Pure electric vehicles use batteries to provide power to the motor. The motor converts electrical energy into kinetic energy to propel the vehicle. Battery performance determines the maximum range and charging time of pure electric vehicles. Therefore, the industry is gradually developing batteries with higher energy density.

Electric vehicle batteries are characterized by their high power-to-weight ratio, specific energy, and energy density: if the electric vehicle battery is lighter, the weight of the vehicle will be lighter, which can improve the performance of the vehicle.

However, as the battery pursues higher energy density, the heat energy generated by the battery during charging and discharging gradually increases, causing the temperature of the battery to rise continuously, and corresponding temperature control is required. If the temperature of the battery is not properly controlled, or the battery is damaged by external forces ( Such as puncture, extrusion), the battery is easy to burn or even explode due to high temperature, and because the high energy density of the battery itself continues to generate heat, the fire generated by it is difficult to cool down and extinguish.
