The BCU controls the pack. This card is responsible of guaranteeing the security of the pack and of the components that are connected to the continuous current bus. Among other actions, it controls main relays, it detects the isolation level and the HVIL status. It has an algorithm that allows predicting faults, so that the pack is capable of adapting to the needs of each moment, reducing the fault's incidence. 


The battery's work mode is defined in this card. It is thus responsible of controlling the amount of current that goes in or out of the complete pack. It also defines the charge, discharge and balancing algorithms to adjust to the needs of each project independently.


The BCU has redundant systems that increase the reliability, obtaining data through independent routes to guarantee that, in case of an incidence, the pack can keep operating with different degrees of fall-back.
