GB/T 19596 Terminology of electric vehicles
3 Terms and definitions
For the purpose of this Part, the terms and definitions given in GB/T 19596 AND the
following apply.
3.1
battery electronics
Electronic device that collects and possibly monitors thermal or electric data of cells or cell
assemblies; it may contains electronics for cell balancing, if necessary.
Note. The battery electronics can include a cell controller. The functionality of cell balancing can be
controlled by the cell electronics or it can be controlled by the BCU.
3.2
high energy traction battery
Traction battery that is designed for the purpose of high energy application.
3.9
high power traction battery
Traction battery that is designed for the purpose of high power application.
3.10
high voltage
A voltage of which the maximum working voltage is greater than 30 V a.c.(r.m.s.) AND
lower than or equal to 1000 V a.c.(r.m.s.); or greater than 60 V d.c. AND lower than or
equal to 1500 V d.c.

5 General test conditions
5.1 General conditions
shall be served as the test results or the basis for calculation.
5.4.2 Preparation of battery system
The high voltage cells, low voltage cells, cell assemblies, cooling devices and the BCU of
battery system shall be connected to the test bench equipment. The active and passive
protections of battery pack shall be activated. The test parameters and conditions of the
test bench equipment shall fulfill the requirements prescribed in the test procedure; the
working parameters of battery system shall be within the reasonable limit range. The
value limits shall be transmitted to the test bench equipment by the BCU via bus
communication. The cooling device shall be operational according to the controls of the
BCU. If necessary, the BCU program shall be adapted by the manufacturer of battery
system for the requested test procedure. During the test of battery system, the battery
system transmits the parameters of battery state and working limits to the test bench
equipment via bus communication; then the test bench equipment controls the test
process according to the battery state and working limits. The current, voltage, capacity or
energy parameters detected by the test bench equipment shall be served as the test
results or the basis for calculation. The uploaded parameters of battery system shall not
be taken as the test result or the basis for test.
5.4.3 Mass and volume of test samples
Use measuring tool to measure the appearance dimensions of test samples; calculate the
volume of test samples in L. Use weighing apparatus to measure the mass of test
samples in kg. If test samples contain forced cooling system, then measurement or
calculation of the mass and volume shall include cooling system, e.g. cooling pipelines,
etc. If cooling system uses liquid cooling mode, then the weight of coolant shall be
counted. If cooling system of test samples integrates with the vehicle or other systems
after cooling, then only the mass and volume related with test samples are taken into
account. When it is difficult to measure, the data and data test basis provided by the
manufacturer ma...
