technical requirements, tests, marks, packaging, transportation and storage for
charging equipment of lithium-ion battery.
This Standard is applicable to the charging equipment for lithium-ion battery
module or lithium-ion battery assembly composed of lithium-ion battery greater
than or equal to 6A·h. It can be also used for the charging equipment for nickel-
based battery and lead-acid battery module and assembly.
This Standard is applicable to the charging equipment that uses cables to
connect to battery module or assembly, with AC rated voltage not exceeding
660V and DC rated voltage not exceeding 1000V.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1 extreme cell voltage
the voltage of the battery cell with the maximum or lowest voltage in the lithium-
ion battery pack; during the charging process, it specifically refers to the voltage
of the maximum voltage battery cell, and in the process of discharging, it refers
to the voltage of the lowest voltage battery cell
3.2 charge interface
the general term for the communication interface and circuit interface of the
lithium-ion battery assembly controller (BECU) connected to the charging
equipment, of which except for the positive and negative connection ports of
the charging power supply, it also includes part or all of the positive and
negative connection interfaces of the network power supply, the charging
control pilot circuit interface, the charging control circuit interface, and the I/O
charging control circuit interface
3.3 on-board charge equipment
the charging equipment installed on motorized device or motor vehicle
3.4 pre-charge
when the minimum voltage of battery cell is lower than the minimum allowable
value, before the minimum voltage of battery cell rises to the minimum allowable
charging voltage, the voltage recovery charging process that uses the current
less than the rated charging current; when the minimum voltage of battery cell
rises above the minimum allowable voltage, the pre-charge process can be
ended, and it will switch to normal charging
4 Models and basic parameters
4.1 Models
A model consists of structure characteristics, cooling method, rated output
voltage and rated output current. The arrangement is shown in Figure 1.
4.3.3 DC power supply
The rated value of DC power supply voltage of the charging equipment shall
meet the requirements of 4.6 in GB/T 156-2007. Preferred values are 110V,
220V, 440V, 600V, 750V, 1000V.
4.3.4 Output voltage range
The minimum output DC voltage of the charging equipment shall be less than
or equal to 50% of the rated output voltage. The maximum output voltage shall
be greater than 110% of the rated output voltage.
When the output voltage range requirement is greater than the above
regulations, it shall be stipulated in the contract.
The preferred value of the DC output rated voltage of the charging equipment
shall be selected from the following values: 16V, 32V, 48V, 63V, 95V, 126V,
200V, 330V, 420V, 530V, 630V.
4.3.5 Output current range
The maximum output current of the charging equipment shall be greater than
or equal to 105%. If the output current range is required to exceed the above-
mentioned stipulations, it shall be stipulated in the contract. The optimization of
the rated output current of the charging equipment shall be selected from the
following values: 2A, 5A, 10A, (16A), 20A, (30A), (40A), 50A, (80A), 100A,
(125A), 160A, 200A , (250A), (300A), (400A), (500A).
NOTE: Bracketed ones are non-preferred values.
