Abstract
A rechargeable battery assembly for a vehicle has a housing and at least one metal-air rechargeable battery arranged in the housing. A filter device is arranged in the housing and conditions the inlet air of the at least one metal-air rechargeable battery such that the inlet air exhibits a predetermined air humidity. A flow deflecting device is provided that deflects the inlet air in the housing such that the filter device can be regenerated by waste heat of the at least one metal-air rechargeable battery.
Claims3
A rechargeable battery assembly for a vehicle, the rechargeable battery assembly comprising:
- a housing having
- an inlet air opening;
- an exhaust air opening;
- at least one metal-air rechargeable battery arranged in the housing;
- a filter device arranged in the housing and configured to condition inlet air of the at least one metal-air rechargeable battery such that the inlet air exhibits a predetermined air humidity before reaching the at least one metal-air rechargeable battery;
- wherein the housing has a first air path channeling inlet air from the air inlet opening to the at least one metal-air rechargeable battery;
- wherein the housing has a second air path channeling heated exhaust air from the at least one metal-air rechargeable battery to the exhaust air opening;
- wherein the filter device comprises a rotary storage device having a drying or sorption agent removing moisture from the inlet air,
- the rotary storage device rotatable to a first position in which:
- a first portion of the rotary storage device is connected to the first air path and receives inlet air before reaching the at least one metal-air rechargeable battery, the drying or sorptive agent removing moisture from the inlet air;
- and
- a second portion of the rotary storage device is connected to the second air path and receives exhaust air from the at least one metal-air rechargeable battery, wherein waste heat in the exhaust air regenerates the drying or sorptive agent in the second portion;
- and
- wherein the rotary storage device is rotatable to a second position in which:
- the second portion of the rotary storage device is connected to the first air path and receives inlet air before reaching the at least one metal-air rechargeable battery, the drying or sorptive agent removing moisture from the inlet air;
- and
- the first portion of the rotary storage device is connected to the second air path and receives exhaust air from the at least one metal-air rechargeable battery, wherein waste heat in the exhaust air regenerates the drying or sorptive agent in the first portion.
