Abstract
A vehicular battery system includes a vehicular battery system stack including at least one negative electrode including a form of lithium, an oxygen reservoir having a first outlet operably connected to the vehicular battery system stack, a multistage compressor having a first inlet operably connected to the vehicular battery system stack, and a second outlet operably connected to a second inlet of the oxygen reservoir, and a cooling system operably connected to the multistage compressor and configured to provide a coolant to the multistage compressor to cool a compressed fluid within the multistage compressor.
Claims18
A vehicular battery system comprising:
- a vehicular battery system stack including at least one negative electrode including a form of lithium;
- an oxygen reservoir having a first outlet operably connected to the vehicular battery system stack;
- a multistage compressor having a first inlet operably connected to the vehicular battery system stack, and a second outlet operably connected to a second inlet of the oxygen reservoir;
- and
- a cooling system operably connected to the multistage compressor and configured to provide a coolant to the multistage compressor to cool a compressed fluid within the multistage compressor.
A method of operating a vehicular battery system comprising:
- charging a vehicular battery system stack including at least one positive electrode including a form of lithium;
- transferring oxygen formed by charging the vehicular battery system stack to a multistage compressor;
- compressing the transferred oxygen in a first compression stage of the multistage compressor;
- compressing the compressed oxygen from the first compression stage in a second compression stage of the multistage compressor;
- providing coolant to the multistage compressor;
- cooling the compressed oxygen from the first compression stage with the coolant;
- and
- transferring the compressed oxygen from the second compression stage to an oxygen reservoir operably connected to the vehicular battery system stack.
