Abstract
A battery management system includes several subsystem blocks, an Energy Storage Master Charger unit, and several battery pack systems. The Energy Storage Master may interface with the Vehicle Master Controller by way of CAN or other communication method to an External Charger. Each battery module within a battery pack may include a Local Module Unit which may communicate with a Pack Master. The Pack Master may communicate with and may be controlled by the Energy Storage Master. Thus, there is a processor to monitor groups of battery cells, a second processor to collect further information about the cell groups, and a third module that takes high-level information from each cell group processor to process and pass on to other vehicle controllers or charger controllers. An integrated BMS may enable cell monitoring, temperature monitoring, cell balancing, string current monitoring, and charger control integration.
