Using programmable DC power supplies to charge batteries, such as Lithium-ion
Customers often submit requests for medium- or high-power battery chargers to serve various projects connected to vehicle electrification (EV), such as e-bikes, hybrid or full electric cars or trucks. These battery chargers are frequently used as part of a test rig for batteries in an EV environment to carry out cycle, performance, and age tests. Also, the test rigs will usually be provided with control, monitoring and safety mechanisms matching the type of battery they are going to test.
Such test rigs aimed at battery testing will require a programmable DC power supply with adequate interface (analogue or digital, e. g. CAN) with high precision, good resolution and low ripple. It can serve as an adjustable and highly flexible DC power backbone, enabling the test rig to connect to numerous different types of battery cells or battery packs with differing nominal voltage and capacities. EAs power supplies have a built in battery charge feature that will automatically stop when the charge voltage is reached or the battery capacity is reached.
