7.2.2 Test Environment
7.2.2.1 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 diffi cult 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.
7.2.2.2 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
can not work normally, but for which one is
bad, it can’t be verifi ed. 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.
