A battery management system and method that allows a battery bank to be composed of battery modules that can be heterogeneous with respect to each other. A battery bank composed of modules that support the battery management system allows for any subset of modules to be easily replaced with modules of different electrochemical characteristics. Each of the modules may also have a controller that manages cells of the module. The bank level controller and module level controller may operate to virtualize the hardware under their management to reduce or eliminate the heterogeneous features of the underlying cells and modules.

System and method for management of heterogeneous battery modules

A vehicle battery packaging for accommodating a plurality of longitudinal battery cells, wherein the battery cells are arranged in a frame in parallel with respect to their longitudinal axes, and wherein each battery cell has a first end and an opposite second end with respect to the longitudinal axis, the battery packaging including: a conductor plate adapted to electrically couple to the second ends of the battery cells; a cooling plate thermally coupled to the conductor plate; and a gap filler layer sandwiched between the conductor plate and the cooling plate.

Vehicle battery packaging

In a longitudinal battery cell for a vehicle battery module, the battery cell includes a first end and an opposite second end with respect to a longitudinal axis of the battery cell, and a lateral surface extending from the first end to the second end. The battery cell includes an attachment structure extending in an outward direction from the lateral surface at the second end for coupling the battery cell to the battery module.

Battery cell having an attachment structure and vehicle battery module

In a conductor plate for a vehicle battery module, the vehicle battery module is adapted to accommodate a plurality of longitudinal battery cells. The battery cells are arranged in parallel with respect to their longitudinal axes, and each battery cell has a first end and an opposite second end with respect to its longitudinal axis. The conductor plate includes: a base part; and a plurality of longitudinal members. Each of the plurality of longitudinal members includes a first end and a second end, the first ends of the longitudinal members being connected to the base part, the base part and the plurality of longitudinal members being substantially arranged in a common plane. The longitudinal members are arranged spaced from each other such that an interval between two of the plurality of longitudinal members matches to an interval between two rows of the battery cells.
