The main reason for requiring a chiller for power limit testing of new energy batteries is to ensure temperature control of the battery during high load operation. ‌

In the testing of new energy batteries, the role of the chiller is mainly reflected in the following aspects:

Temperature control and heat dissipation: Batteries generate a large amount of heat during high load operation. Excessive temperature not only affects the performance of the battery, but also shortens its service life. The chiller provides a stable cooling water flow to help the battery dissipate heat in a timely manner, ensuring that the temperature of the battery is maintained within a suitable range during operation.

Simulate real working conditions: New energy batteries will have different temperature requirements in different working environments and conditions. The chiller can simulate various extreme temperature environments, such as high and low temperatures, to help test the performance of batteries at different temperatures. For example, a chiller can provide precise temperature control support for testing the starting performance of a battery in extremely cold environments or its ability to operate continuously under high temperature conditions.

Improving testing accuracy: Accurate temperature control is crucial for battery performance testing. The chiller can maintain a constant cooling temperature to avoid testing data errors caused by temperature fluctuations. By conducting temperature control tests on different operating states of the battery, researchers can more accurately evaluate key performance indicators such as efficiency, durability, and thermal stability of the battery.

LNEYA chillers are typically equipped with high-precision temperature sensors and controllers that can monitor the temperature of the coolant in real time and automatically adjust the operating status of the refrigeration system based on the set temperature value, ensuring that the temperature of the coolant remains within the set range. Equipped with advanced temperature control technology, it can achieve temperature control accuracy of ± 0.1 ℃ or even higher, meeting the strict requirements for temperature accuracy in lithium battery testing. It has multiple safety protection functions, such as overvoltage protection, overcurrent protection, overheating protection, antifreeze protection, etc., to ensure the safety of equipment and testing personnel.

Select a chiller with appropriate cooling capacity based on the power and heat dissipation requirements of lithium battery testing. Insufficient cooling capacity cannot meet the testing requirements, while excessive cooling capacity can result in energy waste and increased costs. Determine the required temperature range to ensure that the chiller can provide low-temperature coolant that meets the requirements of lithium battery testing. In terms of flow and pressure, it is necessary to consider the requirements of lithium battery testing equipment for coolant flow and pressure, and choose a suitable chiller model.
