BATTERY TEST:
The EDT-150-5191 charger has a battery test (parameterisable) in which the available battery
capacity is measured. This test is performed periodically (also configurable by default every
16 weeks).
During this test, the battery is discharged by its own charge connected to the outputs of the
equipment.
The following is a more detailed description of the process for performing this test:
-
First of all, before starting the test, it should be ensured that:
o
The battery is connected to the output.
o
There is voltage at the AC power supply input of the equipment.
o
The batteries are in float mode and have been in this mode long enough
to ensure that they are fully charged (parameterisable).
o
There is no alarm indicating that the test should not be performed (e.g.
rectifier failure).
-
The rectifier is then disconnected to ensure that all the power requested by the
charges at the outputs is supplied only by the batteries (the DC/DC converters
generating outputs 2 and 3 remain enabled).
-
At that time, the battery current is measured at each instant. Integrating this value
over time gives the remaining battery capacity (Ah supplied).
-
This operating condition is maintained until:
o
The configured (parameterisable) minimum capacity is reached, i.e:
▪
The test is considered passed and is considered completed.
▪
It is calculated when the next test should be performed.
o
The maximum time defined for each attempt is reached (parameterisable),
in which case:
▪
The test is considered passed and is considered completed.
▪
It is calculated when the next test should be performed.
o
The battery voltage level limit is reached to consider the test as failed
(parameterisable), in which case:
▪
This attempt shall be deemed to have failed:
•
If all planned retries have been performed:
o
The current test will be completed.
o
The test shall be deemed to have failed.
o
The "Battery failure" alarm will be generated.
o
The periodic execution of the battery test will be
blocked.
o
The rectifier is restarted and enters the constant
voltage charging mode.
•
If not all the planned retries have been performed, a new
one will be started:
o
The rectifier will be restarted and will enter
constant voltage charging mode (fast charging).
