Chillers for Energy Storage System

Chillers for Energy Storage System is a kind of cooling equipment used in the field of energy storage, so what exactly does the energy storage system refer to? What are the temperature control technologies in the field of energy storage? What are the working principles of energy storage liquid cooling?

1. Introduction of energy storage system:

The energy storage system mainly refers to the battery energy storage system, which is generally composed of a battery system, a PCS system, a BMS system, and a monitoring system. The battery system is composed of battery cells connected in series and parallel. According to the current common air-cooled energy storage containers, thousands of batteries are stacked together to work, and the energy storage system will generate a lot of heat during charging and discharging. These heat needs Distribute it in time, otherwise it will affect the battery life, and even cause thermal runaway and bring risks.

2. Introduction to the types of temperature control technologies in the field of energy storage:

In the energy storage system, the current low-power systems, such as charging treasures, mobile phones, laptops, etc., generally use natural heat dissipation, and medium-power systems, such as portable power supplies, household energy storage systems, UPS, and industrial small and medium-sized containers Energy storage, etc., generally adopts forced air cooling; electric vehicle energy storage systems generally adopt liquid cooling technology. At present, medium and large energy storage systems have also begun to adopt liquid cooling technology.

At present, the temperature control technologies in the field of energy storage mainly include air cooling and liquid cooling. Air-cooled heat dissipation technology is extended from air conditioners, and liquid-cooled technology is borrowed from electric vehicles. The air-cooled heat dissipation uses the fan to bring the heat generated by the battery cells to the outside, and the liquid-cooled heat dissipation uses the convective heat exchange of the coolant, which can accurately manage the temperature of each battery cell. Air-cooling technology was commonly used in early energy storage systems because of its simple structure, mature technology, and low cost, which can be quickly delivered and deployed. However, the air-cooling system is large in size and is greatly affected by the external environment. There are many problems in terms of performance, and the emergence of liquid-cooled energy storage just solves the above problems.

3. Introduction to the working principle of the liquid cooling system in the field of energy storage:

The liquid cooling system of Chillers for Energy Storage System is currently a popular direction for power battery thermal management. It utilizes the performance of coolant with large heat capacity and the ability to remove excess heat from the battery system through circulation to achieve suitable working temperature conditions for battery packs. The basic components of the liquid cooling system include: liquid cooling plate, liquid cooling unit (heater optional), liquid cooling pipeline (including temperature sensor, valve), high and low voltage wiring harness; cooling liquid (ethylene glycol aqueous solution), etc.

The cooling circuit of Chillers for Energy Storage System generally adopts a parallel circuit to reduce the temperature difference between battery packs; battery packs generally use large battery boxes to improve system integration and reduce costs; liquid cooling units are arranged in distributed and centralized There are two types. Distributed use one cluster or two clusters to configure a liquid cooling unit, generally used for a single outdoor cabinet; centralized use a container system to configure one or two liquid cooling units.
