Battery Short Circuit Protection Testing Machine

Product description:

According to the latest national standard GB / T 31467.3-2015 "lithium-ion battery packs and systems for electric vehicles Part 3: Safety requirements and test methods" requirements and integrated a variety of short-circuit test standards and design requirements, according to the standard requirements of short circuit devices must Meet the resistance range of ≤ 20mΩ or (5mΩ), so as to obtain the maximum test short-circuit current; so the external short circuit protection device must also be able to withstand the impact of high current. No leakage of the battery system, shell rupture, fire or explosion and other phenomena for the party.

Specification:

1 test object: battery system
