Shanghai Research Institute of Chemical Industry
3.Battery test items
 Electrical safety tests
Over-voltage charge
Over-current charge
Over-voltage discharge
Over-current discharge
External short circuit
Reverse charge
ESD test
Shanghai Research Institute of Chemical Industry
4.Test items for protection circuit
module (PCM) –safety requirements
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
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
.
