Features of ACB (Active cell balance)
Methods to regulate the equalization of series batteries include passive balancing methods using conventional technology and active balancing methods using new technology.
ACB enables management of battery systems (battery cells connected in multiple series) as if they were a single battery.
Accordingly, the following effects can be expected.
1) Improved safety of battery systems
2) Reduced burden on specific battery cells, prolonging battery life
3) Extended range for EV vehicles
Features of AMB (Active module balance)
AMB compensates for the slight differences in voltage and capacity between modules in series batteries.
It enables the transfer of power among desired modules, and the balancing of voltage or electric energy.
It also enables compensation for any differences in each module’s total voltage.
(This operation can be performed among modules with a different number of series.)
Features of IHS (Intelligent hot plug switch)
IHS manages the voltage of multiple battery packs connected in parallel (battery rack), connecting and switching ON only when within the usable voltage ranges for each battery pack (battery rack), and switching OFF outside those ranges.
Connecting multiple battery racks in parallel with IHS enables all battery packs to fully utilize their capabilities.
