Foreword
There is currently no technical guidance document of lithium-ion batteries for electric
road vehicles in our country and other countries. Therefore, the formulation of this
technical guidance document refers to IEC 61960-2 Draft (21A/244/CD) “Lithium-Ion
Batteries and Battery Packs Used by Portable Equipment”; in which, because only low-
power lithium-ion batteries and battery packs are involved, which are different from
high-power batteries and battery packs, therefore, appropriate addition-deletion are
made in this respect. When determining the content of this technical guidance
document, on the one hand, technical requirements of electric road vehicles are
accorded with; on the other hand, the current level of lithium-ion batteries development
in our country shall be taken into account as well; not only shall the current
requirements be met, but also shall the long-term development be considered.
The Annex A of this technical guidance document is a suggestive annex.
This technical guidance document was proposed by State Administration of Machinery
Industry.
This technical guidance document shall be under the jurisdiction of National Technical
Committee of Automobile Standardization.
Drafting organizations of this technical guidance document. No.18 Electronic Research
Institution of Ministry of Information Industry.
Participating drafting organizations of this technical guidance document. Beijing
General Research Institute for Nonferrous Metals, Institute of Physics in Chinese
Academy of Sciences.

3 Definitions and symbols
This technical guidance document has added the following definitions, in addition to
applying definitions in GB/T 2900.11.
3.1 Charge recovery
The ratio of discharge capacity TO the rated capacity of charged batteries which have
been stored for a certain time at a certain temperature.
3.2 End current at charge
The current of batteries at the end of charging when the batteries are charged in
specified constant voltage.
3.3 Specific characteristics
The ratio of electrical performance of batteries TO the unit mass of batteries, unit
surface area or unit volume.
3.4 Explosion
Battery cell case is broken. Internal substances erupt from the battery and make a
sound of explosion.
3.5 Fire
There is a fire in the shell of batteries.
3.6 Leakage
The original weight of batteries reduces over 0.1% due to the loss of liquid electrolyte.
3.7 Venting
Excessive internal pressure releases from batteries to avoid explosion.
3.8 Nominal energy
At temperature of 20°C ± 5°C, discharged by 1I3 (A) current, the energy (Wh) that can
be released from battery when reaching the final voltage. This value can be obtained
from cover area integral of voltage-capacity curve, which requires 50 equivalent-value
time-intervals at least, or be calculated directly by integrator.
3.9 Symbols
C3 - rated capacity of 3 hours.
I3 - discharge current of 3 hours, its value is 1/3C3(A).
4 Classification and models
4.1 Classification
Batteries for electric road vehicles can be classified into prismatic batteries and
cylindrical batteries.
4.2 Models
capacity (measured as per Ah). And charge retention can be expressed as the
percentage of rated capacity.
6.10.5 Batteries use the charger provided or recommended by the manufacturing plant.
At 20°C ± 5°C, stored batteries (6.10.2) are charged in 24 h until the end.
6.10.6 The batteries are discharged by 1I3 (A) current at 20°C ± 5°C until discharging
is stopped.
6.10.7 USE the figure of current value and discharge time in 6.10.6 to calculate
capacity (measured as per Ah). And charge retention can be expressed as the
percentage of rated capacity.
