Charging the cells by a laboratory power supply

26.Jul 2019

Many of the laboratory power supplies allow charging of the individual cells. Using such a regulated power supply is a suitable method for performing the initial charging or for the balancing of a single cell in a battery pack (by means of charging to a fixed voltage level).

There are usually 3 steps to follow:
1) set the target voltage (open voltage) – without the connection of the battery, up to 3.65V,
2) start charging and set the current to be used (3.0 A in the picture)
3) when the charger reaches the target voltage, it usually starts to reduce the charging current until a low value. When the battery reaches the set voltage level, it is a moment to stop charging and disconnect the charger.
