Charging individual cells using the regulated (laboratory) power supply
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 (3.65 at the picture),2) start chargingand set the current to be used (3.0 A at the picture),3)when the charger reaches the target voltage – it usually starts to reduce the charging current until a low value. (3.66 V reached at 0.04A). It isa time to stop chargingand disconnecting the charger.
