Flexible bus architecture for monitoring and control of battery pack

A control system for reconfiguring communication path in a stacked battery, comprising:

• a control unit;
• a plurality of processors coupled to the stacked battery and capable of receiving information from the control unit;
• a plurality of controllers coupled to the stacked battery, two adjacent controllers communicating with each other through a second vertical bus, each processor being capable of receiving information from an adjacent controller through a lateral bus;
• and
• a first plurality of isolators coupled to the plurality of processors, two adjacent processors of the plurality of processors communicating with each other through one isolator, the first plurality of isolators being coupled in a star fashion to the control unit,
• wherein the control unit reconfigures the communication path among the plurality of processors and the plurality of controllers according to the information received back from the plurality of controllers.

A system for controlling a plurality of battery packs, each battery pack having a plurality of battery cells coupled in series, the system comprising:

• a control unit;
• a plurality of processors connected in series, each processor being in communication with one adjacent processor through a first bus, at least one processor being in communication with the control unit;
• a plurality of controllers for balancing loads of the plurality of battery cells, each controller being in communication with an adjacent controller through a second vertical bus;
• and
• a first plurality of isolators in communication with the plurality of controllers, a isolator connecting a controller to a second bus,
• wherein the control unit communicates with the plurality of controllers through the second bus.
