Abstract
A battery system comprising a plurality of stacks of battery cells. Each stack of battery cells has an annular shape. A main battery management system (BMS) operatively connected to at least one of the stacks of battery cells. The main BMS includes an annular housing and a motor drive assembly positioned within an inner diameter hole of the annular housing configured and adapted to drive circulation of a heat transfer fluid around the plurality of stacks.
Claims20
A battery system comprising:
- a plurality of stacks of battery cells, wherein each stack of battery cells has an annular shape;
- and
- a main battery management system (BMS) operatively connected to at least one of the stacks of battery cells, wherein the main BMS includes an annular housing and a motor drive assembly positioned within an inner diameter hole of the annular housing configured and adapted to drive circulation of a heat transfer fluid around the plurality of stacks.
A method of controlling heat transfer in a battery system, the method comprising:
- monitoring at least one characteristic of a battery cell within a battery system with a battery management system (BMS);
- and
- selectively varying a fluid circulation rate in the battery system with the BMS depending on the at least one characteristic.
