Battery Management System
Lithium-ion batteries are now mega-popular. They have found wide application in portable electronics.But unlike other types of batteries, for example, lead-acid or nickel batteries, lithium-ion batteries are very demanding for the charger parameters.
If you don’t control the process of charging and discharging of such batteries, they will fail soon.The banks can swell and even explode from overcharging, and a deep discharge can cause of battery failure.
The ideal charger for lithium-ion batteries should have a stabilizing unit for voltage and current and also a voltage balancing system for banks.The voltage of the fully charged can of lithium-ion the battery is 4.2 Volts.
As soon as the bank has reached this voltage, the charging process should stop.Today we will examine a circuit that will allow charging lithium-ion cans connected in series, as well as balancing them in the process of charging.This circuit is not only simple, but also very effective.
