Battery Short Circuit Test Chamber (Room Temperature Type)

Scope of Application:

This equipment is suitable for primary lithium batteries and other primary batteries, as well as lithium-ion batteries used in digital electronic products such as mobile phones, laptop computers, and cameras. It is also applicable to nickel-metal hydride (NiMH), nickel-cadmium (NiCd), and lead-acid batteries used in products such as power tools, toys, and electric bicycles.

Test Purpose:

This equipment is designed in accordance with the requirements of multiple battery short-circuit test standards. As specified by the standards, the short-circuit device must meet an internal resistance range of 80 ± 20 mΩ (or ≤ 10 mΩ) in order to obtain the maximum short-circuit current required for testing.In addition, the circuit design of the short-circuit device must be capable of withstanding high-current impact. Therefore, industrial-grade DC electromagnetic contactors, full copper terminals, and internal copper busbars are adopted. The wide and thick copper busbars effectively improve heat dissipation, making the high-current short-circuit device safer, reducing equipment wear during testing, and ensuring the accuracy and reliability of test data.
