A method of recycling battery packs having a plurality of battery units is disclosed. The battery units have positive and negative terminals combined with each other and are supported within a housing. The battery units are separated from battery packs subsequent to the one or more battery packs being judged as being degraded. Each of the battery units is tested with a battery test stand having a fixed resistance load to obtain battery operating data indicative of variable voltage and variable current. The battery units are matched based on the battery operating data to form sets of matching battery units. And, replacement battery packs are formed by connecting positive and negative terminals of the matching battery cells within the sets.

Reconditioned battery pack and method of making same

A battery system is described. The battery system includes a power controller having sensors monitoring the state of predetermined sections of battery modules within battery packs and sends signals to a switching network to connect a bi-directional DC/DC converter to a first predetermined group of battery modules of the plurality of predetermined groups of battery modules at a first instant of time responsive to a first measurement of a first predetermined section of battery modules, and a second predetermined section of battery modules of the plurality of predetermined groups of battery modules at a second instant of time responsive to a second measurement of a second predetermined group of battery modules.
