Chiller unit for power limit testing of new energy batteries

The working principle of power limiting mode: When the system detects low battery level or high temperature, it will automatically enter power limiting mode to avoid excessive use of the battery and protect the battery and motor. Testing method: Evaluate the performance and stability of the battery in limited power mode by simulating these extreme conditions.

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:

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.
