Testing a battery module

Testing a battery module is obviously an extension of testing a battery cell. Again, we can perform the following tests: Determining the impedance of the battery module Determining module capacity The number of charge/discharge cycles We now know the effect of charging with too high a voltage and discharging a Li-ion battery too deeply when looking at a battery cell. (...)

Testing a battery cell

In the picture opposite, you can see a nice representation of the structure of a battery cell. Thus, you can also clearly see the anode, the separator and the cathode. In addition, the insulation material, the housing and the positive and negative terminals. What tests can we perform on such a cell? The battery cell insulation test Determining the impedance (...)

Charging methods

A distinction is made between four charging modes where the term ‘mode’ refers to the charging technology (power, communication and safety). Mode 1 is unlimited charging via a standard 230V AC outlet. The maximum charging current is 10A depending on the region. Such a charging method works without a current limiter and is therefore hardly ever used for larger vehicles (...)

Solar inverter test solutions

A solar inverter system consists of several components; Solar panels The solar inverter The grid or microgrid And optional batteries To easily test the solar panel inverter, we use emulation equipment for solar panels, batteries, the grid or in a microgrid simulation the AC load. For a comprehensive overview of the different emulation devices, please visit the following pages: Solar (...)
