Cooling device in energy storage power station

Why are energy storage systems important?

Energy storage systems (ESS) have the power to impart flexibility to the electric grid and offer a back-up power source. Energy storage systems are vital when municipalities experience blackouts, states-of-emergency, and infrastructure failures that lead to power outages.

Can a thermoelectric cooling system run on a DC power supply?

A cooling system that operates on a DC power supply such as a thermoelectric cooler would not be susceptible to black-outs or brown-outs, allowing the ambient temperature of the battery back-up system to be kept constant.

Why do thermoelectric coolers use DC power?

Using DC power allows thermoelectric cooler assemblies to remove heat at a rate proportional to the power applied, so when cooling needs are low, less energy is used to maintain temperature control. This compares favorably relative to the “on”/“off” operation of compressor-based systems.

How does a thermoelectric cooler work?

Thermoelectric coolers serve a cooling capacity spectrum from approximately 10 to 400 Watts, and can cool by removing heat from control sources through convection, conduction, or liquid means. Thermoelectric devices operate using DC power, leaving them less vulnerable to the black-outs and brown-outs that can impact other types of cooling systems.

What is a thermoelectric cooler?

Thermoelectric cooler assemblies also provide precise temperature control with accuracies up to 0.01 ̊C of the set point temperature, due to their proportional type control system. The operating range for a typical thermoelectric cooler is -40 ̊C to +65 ̊C for most systems.

Do battery back-up systems need to be cooled?

Battery back-up systems must be efficiently and effectively cooled to ensure proper operation. Heat can degrade the performance, safety and operating life of battery back-up systems. Traditionally, battery back-up systems used custom compressor-based air conditioners.
