Charge rate modulation of metal-air cells as a function of ambient oxygen concentration
First Claim
Patent Images
1. A method of charging a metal-air battery pack mounted within an electric vehicle, the method comprising the steps of:
- coupling said metal-air battery pack to an external charging power source via a battery charging system;
determining an oxygen concentration level within a first region corresponding to said electric vehicle;
comparing said oxygen concentration level to a preset oxygen concentration level;
initiating charging of said metal-air battery pack if said oxygen concentration level is less than said preset oxygen concentration level;
suspending charging of said metal-air battery pack if said oxygen concentration level exceeds said preset oxygen concentration level; and
resuming charging of said metal-air battery pack when said oxygen concentration level falls below said preset oxygen concentration level.
