3.3 System Working Environments Checking
3.3.1 Cleaning
The battery system has high voltage connectors. The clean condition will cause the isolation
characteristic of the system.
Before installation and system working must clean the dust and iron scurf to keep the
environments cleaning. And the environment must have certain anti-dust ability.
The system after long term running must check the humidity and dust cover or not. If heavy dust
cover with high humidity on the system should stop the system running and make clean specially
for the high voltage connectors.
Danger:
the power cables and plugs still have high voltage DC power from serial connected
battery modules (battery module can’t be turned off), must be careful to handle the
Power Plugs.
3.3.2 Temperature
PowerCube-M1 system working temperature range: 10
℃～
40
℃
; Optimum temperature: 18
℃～
28
℃
.
Caution:
Out of the working temperature range may cause the battery reduces the cycle of life
even cause the battery system over / low temperature alarm or protection.
3.3.3 Cooling System
The room must be equipped with cooling system.
Caution:
Out of the working temperature range may cause the battery reduces the cycle of life
even cause the battery system over / low temperature alarm or protection.
3.3.4 Heating System
The room must be equipped with heating system. If the environment is lower than 0
℃
, must turn
on the heating system at first.
Caution:
Out of the working temperature range may cause the battery reduces the cycle of life
even cause the battery system over / low temperature alarm or protection.
3.3.5 Fire-extinguisher System
The room must be equipped with fire-extinguisher system for lithium-ion battery.
The fire system needs to be regularly checked to be in normal condition. Refer to the using and
maintenance requirements of local fire equipment relevant.
3.3.6 Grounding System
Before the battery installation must sure the grounding point of the basement is stable and
reliable. If the battery system is installed in an independent equipment cabin (e.g. container),
must make sure the grounding of the
cabin is stable and reliable.
The resistance of the grounding system must
≤
100mi
