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
4 Symbols
The following symbols apply to this document.
Cn - nominal capacity, in amperes (A·h).
Wn - nominal energy, in Watts hours (W·h).
5 Test requirements
5.1 Safety requirements

the process of test of residual capacity shall be in accordance with 6.1.2 of
GB/T 31486-2015.
6 Test procedure
6.1 The test of residual capacity for traction battery used in electric vehicle
shall be carried out according to the work flow shown as Figure 1.
6.2 Appearance inspection
Traction battery
6.2.1 In good light conditions, visually inspect the appearance of traction
battery module, the appearance of the monomer. If there are s deformation,
cracks, leakage, etc., the test of residual capacity shall not be carried out.
6.3 Information collection

of the battery, such as the nominal voltage, nominal capacity or nominal
energy, etc.
6.5 Determination of first charge and discharge currents
6.5.1 Battery cell
6.5.2 Battery module
6.5.2.1 There is 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 can be obtained directly.
The first charge and discharge currents shall be initially determined according
to the information.
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).
