Recycling of traction battery used in electric vehicle -
Test of residual capacity
1 Scope
This Standard specifies the terms and definitions, symbols, test requirements,
test procedures and test methods for test of residual capacity of recycling of
traction battery used in electric vehicle.
This Standard applies to the test of residual capacity of recycling of lithium-ion
traction battery and metal hydride nickel-powered battery cell, module used in
electric vehicle.
2 Normative references
The following referenced documents are indispensable for the application of
this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including
any amendments) applies.
GB/T 19596, Terminology of electric vehicles
GB/T 31486-2015, Technical requirements and test methods for traction
battery of electric vehicle - Electrical performance
3 Terms and definitions
For the purposes of this document, the terms and definitions defined in GB/T
19596 and the following ones apply.
3.1 residual capacity
the actual capacity remaining after the traction battery is removed from the
electric vehicle
3.2 discharge capacity at I5
the capacity of traction battery discharged (A·h) at 1 I5 (A) of current to reach
termination voltage at room temperature
NOTE. This value can be obtained from the integral of the coverage area of the
capacity or nominal energy and battery module nominal voltage, nominal
capacity or nominal energy and other information can be obtained directly.
The first charge and discharge currents shall be initially determined according
to the information.
6.5.2.2 There is no a label in which cell number, nominal voltage, nominal
capacity or nominal energy and battery module nominal voltage, nominal
capacity or nominal energy and other information cannot be obtained directly.
The battery module shall be disassembled. And the first charge and
discharge currents shall be determined according to Table 1.
6.6 Determination of I5
Use electrical performance tester to carry out the charge-discharge test in a
mode of first charge-discharge constant current. Calculate I5 according to
equation (1).
where,
I5 - 5h rate discharge current, in amperes (A);
Cf - battery capacity measured in first charge-discharge constant current, in
amperes hour (A·h).
6.7 Material identification
Use electrical performance tester for charge and discharge test. Perform
preliminary determination of battery material category.
