Hi. Battery equalisation is a process done to (mainly) FLOODED Lead Acid Batteries. This involves charging the battery to 100% and then raising the charge voltage to 15.5V for a 12V battery. AGM batteries should not need equalising unless specified by the manufacturer. The process is programmed into your normal charger, and you don''t need any ...
Nowadays, Lithium-based batteries are becoming the research focus in the area of electric vehicle design because of their high terminal voltage, large energy density and lack of memory effect [1,2,3].To meet the requirements of high voltage and power, they were commonly connected in a string [].Due to the manufacturing variances, internal impedance variations, …
