Search for the most optimal mode of operation of the individual battery charger of high-voltage battery consisting of Li-ion modules.
1st step or Iz1 = 0.024 Cnom
or just Iz1 = 1.5A
2nd step Iz2 = Iz1 + d*Iz1 n
where ( d*Iz1 ) or 0.005 Cnom or 0.5 A
3rd step Iz3 = Iz2 + 0.5A
4th step Iz4 = Iz3 + 0.5A
By time: 1 stage – 1 hour
2, 3, 4 – 0.5 hours each
At this stage, there is a steady progressive increase in the value of Uz.
Led until Izmax reached
In the first version of the charger Izmax = 5A
5th step Iz5 = Iz4 +0.5 A = 3.5 A
6th step Iz6 = Iz5 +0.5 A = 4 A
7th step Iz7 = Iz6 +1 A = 5 A
Proceed when maintaining the level of the 6th stage Iz = 5A until the value of Uz = 4.1 V at the pole terminals of the weakest Li-ion cell and suspend the charge by switching to a electric current pause.
Withstand a 30 minute pause. Re-start the charge according to the algorithm of 1 stage, which leads to the achievement of Uz = 4.1 V at the pole terminals of the weakest Li-ion cell and stop the charge.
