Bidirectional Power Supply Repeatably Tests Battery-powered Equipment
Testing battery-powered equipment can be tricky because battery performance varies from unit to unit, once they are discharged, you have to suspend testing until they’ve been charged again. You can, however, use EA’s bidirectional power supplies, such as the EA PSB-10000 to simulate a charging or discharging battery during an automated test. This allows testing under various battery conditions without having to wait for a battery to charge or discharge to a specific state-of-charge. In addition, we provide battery simulation software for Windows PCs, the EA Battery Simulator.
This software can control one or more EA-PSB 10000 power supplies to simulate standard lead-acid (AGM) and lithium-ion batteries in series or parallel connection for a wide variety of battery related tests. The user can adjust battery parameters for a test, and once a test has started, it runs automatically. The combination of a bidirectional power supply and this software eliminates the need for maintaining a bank of batteries for testing, while at the same time providing a wide range of test voltages and charging/discharging currents that are reliable and repeatable.
