Description

The Charger block implements an ideal battery charger. When the signal at the input port, t, changes from a value below 0.5 to a value equal to or greater than 0.5, this block performs constant current charging at the value of the Constant charging current parameter. When the voltage is greater than or equal to the value of the Voltage threshold parameter, this block performs constant voltage charging at the value of the Constant charging voltage parameter until the current is less than or equal to the value of the Current threshold parameter.

This figure shows the behavior of the Charger block when the t input crosses 0.5:

Charge Battery Module with Charger Block

Charge a battery module using a constant-current step followed by a constant-voltage step. This is a CC-CV profile. The battery simulation utilizes a Simscape™ Battery™ Charger block. At the start of the simulation, the battery module has a state of charge (SOC) of 10%. The Charger block performs a constant-current (CC) charging until it reaches the predefined module voltage limit of 4.1 V. The block then switches to a constant-voltage (CV) control step where the current gradually decreases until it reaches a threshold of 0.5 A, specified in the Current Threshold parameter. The charging procedure stops once the current reaches the designated threshold.
