There are generally two types of voltage-based balancing for lithium batteries: top and bottom balancing. Top balancing is practical for small electric vehicles as charging overnight fills up and balances the batteries. Larger and heavier electric vehicles, on the other hand, do not enjoy such convenience. They need proper infrastructure just to charge quickly without problems with the local electric grid. Factoring balancing delay with other considerations could mean bottom balancing might be more appropriate. This paper analyzes the balancing time as well as other considerations when choosing whether to utilize top or bottom balancing for high-capacity battery systems in electric vehicles.
