1.What do portable electronic equipments include ?
Shanghai Research Institute of Chemical Industry
Power bank is not included in GB31241,
Relative standard are being made. There may be some additional
requirements for lithium ion batteries used in special fields such as medical , miner ,work on the bottom of the ocean
1.What do portable electronic equipments include ?
Shanghai Research Institute of Chemical Industry
Test condition Capacity test Cell conditionGeneral safety requirements Mark requirement Electrical safety test External short circuit at RT External short circuit at 55C Overcharge test
2. Cell test items
Shanghai Research Institute of Chemical Industry
Forced discharge Environmental tests Altitude simulation Temperature cycle Vibration test Mechanical shock Free fall Crush Impact test
2. Cell test items
Shanghai Research Institute of Chemical Industry
Abusive heating Projectile
2. Cell test items
Shanghai Research Institute of Chemical Industry
Test condition Battery condition Label requirement Duration Environmental test Altitude simulation Temperature cycle
3. Battery test items
Shanghai Research Institute of Chemical Industry
Vibration test Mechanical shock Free fall Mode stress relief High temperature test Washing test Enclosure fireproof requirement (V1)
3. Battery test items
Shanghai Research Institute of Chemical Industry
Electrical safety tests Over-voltage charge Over-current charge Over-voltage discharge Over-current discharge External short circuit
Reverse charge
ESD test
3.Battery test items
Shanghai Research Institute of Chemical Industry
Over-voltage charge protection Over-current charge protection Over-voltage discharge protection Over-current discharge protection External short circuit protection High –voltage test If PCM can pass these tests, It can be
kept in the electrical safety test for battery . Or will be removed
4.Test items for protection circuit module (PCM) –safety requirements
Shanghai Research Institute of Chemical Industry
5.Test items for PCM in host
Charge voltage control Charge current control Discharge voltage control Discharge current control Temperature control during charge
or discharge
Shanghai Research Institute of Chemical Industry
6.Current Condition
This is compulsory standard to come into effect on August 1 ,2015
It is possible for China to put lithium ion cells and batteries into CCC catalogue based on this standard .
The laboratory of Shanghai Research Institute of Chemical industry was the contracted laboratory of CQC (China quality center )
Shanghai Research Institute of Chemical Industry
6. Current Condition
CQC will issue the volunteer certification with SRICI’s test data and will issue CCC certification if lithium ion cells and batteries are put into CCC catalogue.
You will get one UN38.3 free if you apply for UN38.3 and GB31241 at the same time .
