BATTERY PACK FOR VEHICLE ENERGY-STORAGE SYSTEMS

摘要

Provided are battery packs. Each pack may comprise a first plurality of strings electrically coupled to each other in parallel, each of the first plurality of strings providing substantially an output voltage and comprising: a first plurality of battery modules comprising: a plurality of high power battery cells, each of the plurality of high power battery cells having a higher power specification than a plurality of high energy battery cells; and a second plurality of strings electrically coupled to each other and to the first plurality of strings in parallel, each of the second plurality of strings providing substantially the output voltage and comprising: a second plurality of battery modules comprising: the plurality of high energy battery cells, each of the plurality of high power battery cells having a higher energy specification than the plurality of high power battery cells.

主权项

1. A heterogeneous battery pack comprising:
a first plurality of strings electrically coupled to each other in parallel, each of the first plurality of strings providing substantially a first output voltage and comprising:
a first plurality of battery modules electrically coupled to each other in series, each of the first plurality of battery modules providing substantially a second output voltage and comprising:
a substantially homogeneous set of high power battery cells, each of the plurality of high power battery cells providing substantially a third output voltage and having a higher discharge rate and lower charge storage capacity than a substantially homogeneous set of high energy battery cells; and a second plurality of strings electrically coupled to each other and to the first plurality of strings in parallel, each of the second plurality of strings providing substantially the first output voltage and comprising:
a second plurality of battery modules electrically coupled to each other in series, each of the second plurality of battery modules providing substantially the second output voltage and comprising:
the substantially homogeneous set of high energy battery cells, each of the plurality of high energy battery cells providing substantially the third output voltage and having a higher charge storage capacity and lower discharge rate than the substantially homogeneous set of high power battery cells.
