“A method for charging a metal-air battery pack at the maximum possible rate while maintaining an ambient oxygen concentration below a preset concentration is provided, thereby minimizing the risks associated with generating oxygen during the charging cycle.”
There are problems with metal-air battery technology that need to be solved in order for it to be used in electric vehicles, especially life cycle and cost. In the patent, Tesla asserts that the new charging method addresses some of the issues, like managing the supply of air during the charge cycle.
