Battery Testing
A DC load is well suited to verify that a battery is working properly. Only with the correct load testing, the battery can be confirmed if it was being the expectant life curve location. The electronic loads can be used to test any type of battery.
As the accumulator is used by any sheltered equipment or the uninterrupted service system, it is necessary to use load testing. Because the battery is the weakest component, load testing should be used periodically to ensure the security of the battery.
Capability test
For the capability test CC mode is used. Generate a program to set the voltage in off state. If the accumulator’s voltage is too low, the electronic load will interrupt the test if system checks the accumulator which is near to one rating or in insecurity state. In testing procedure, you could see the accumulator voltage, discharge current, electronic load power and spare capability of accumulator. If connecting with PC software, the battery’s discharge curve could be displayed in window. This test can reflect the reliability and usage time of accumulator.
Operation:
(1) Turn off the input of electronic load, then connect the load with battery.
(2) Press | on the panel, VFD displays "CURRENT= A", set discharge current value and press Enter to |
confirm.
Note: the discharge current should not be more than the current that the battery can supply.
(3) | Press | Shift | + Battery , VFD displays "MIN VOLT= V", set the min voltage value, press Enter to start |
| the test. When the battery voltage reaches as the min voltage, the battery test will stop. During the testing, press | ||
| the down key▼and up key▲ to observe the voltage, current and discharge capacity of the battery, and the power | ||
| of the load. |
| |
(4) | Press | Shift | + Battery to stop battery test. |
