5.3 Common terms for lithium-ion
power batteries
5.3.1 Battery system
The battery system is an energy storage device
that typically includes one or more battery
modules, battery management systems, thermal
management systems, high/low voltage wiring
harnesses,
connectors,
and
structural
components.
5.3.2 SOC
The ‘State Of Charge’ (SOC) of a battery is a
measurement of how much energy is remaining
(percent).
5.3.3 Rated voltage
It is an approximate value used to indicate the
battery voltage.
5.3.4 Rated capacity
Under the specified conditions, the electric
capacity provided by the fully charged battery,
which is indicated by the manufacturer.
5.3.5 Over-discharge
The state when the battery voltage is below the
discharge cutoff voltage, and it usually refers to
the discharge state after the battery is fully
discharged.
5.3.6 Overcharge
The state when the battery voltage is higher than
the maximum charging voltage and at this time it
can usually be regarded as battery overcharge.
5.3.7 Explosion: The battery housing is broken and
solid material is flushed out of the battery with an
explosive sound.
5.3.8 Fire: Open fire comes out of the battery
shell.
5.3.9 Leakage: The internal composition of the
battery (electrolyte or other substances) leak out
of the battery.
5.3.10 CAN communication: communication via
control area network.
5.4 Instructions for use
5.4.1 Battery temperature characteristics:
• Allowable charging temperature: 0°C - 50°C
• Allowable discharging temperature: -28°C - 55°C
• Storage ambient temperature: -28°C - 55°C
5.4.2 Checks before use
Make sure there is no battery system alarm
message on the dashboard after the ignition key
switch is turned off. Please check the remaining
battery capacity before use, it is recommended to
use the truck when the battery SOC is within the
range of 50% - 100%.
5.4.3 Instructions for charging:
（
1
）
Charge the battery promptly when the
battery system's SOC is below 20%.
