GB / T 31467 Battery Testing Equipment , Battery Pack System 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
2. Test object in the test All control systems are in working
condition.
3. Short the test object terminal 10min.
4. Short-circuit resistance is not more than 20mΩ, both parties
agreed. Observation 2h.
