11.2 Test Environment
11.2.1 Test environment
Inside the vehicle test indicates that the battery connects to loading devices,
such as engine, etc. After doing battery test, it can perform charging system and
actuation system test, which is proceeded as a whole simultaneously. Charging
system and actuation system test is not required but must not be performed
before battery test. Because it is difficult for vehicle technicians to judge where is
faulty exactly if they have the faintest idea of battery’s status itself.
Outside the vehicle test indicates that the battery is disconnected from all
loading devices on vehicles. Therefore, only battery test is supported in this
condition.
11.2.2 Battery status and description
There are mainly 5 states as follows:
No.
States Descriptions
1
Good battery Indicates battery is normal.
2
Replace battery
Indicates that battery is aged or becomes rejected, or
battery life cycle approaches to be exhausted. In this
case, battery voltage appears to be normal, but
battery itself is not well, i.e. battery polarity board has
been completely vulcanized or aged. Please replace
battery immediately.
3
Good-recharge
Stands for low battery. The battery is good itself.
4
Charge-retest
It is better for a few batteries to be fully charged
before testing in order to avoid judging in error under
special conditions.
5
Bad cell
Indicates one of the battery cells is bad and cannot
work normally, but for which one is bad, it can’t be
verified. In this case, battery voltage is generally lower
than 11V, mainly resulting from internal circuitry
damage, such as short circuit, open circuit, dummy
weld etc.
