Abstract
A method for charging a motor vehicle battery includes determining the electrolyte resistance frequency of the cell, determining the battery charge transfer resistance frequency, and charging the battery with a current at a charging current frequency greater than the electrolyte resistance frequency of the battery and less than the battery charge transfer resistance frequency.
Claims10
A method for charging a motor vehicle battery, comprising:
- determining the electrolyte resistance frequency of the battery,
- determining the charge transfer resistance frequency of the battery, and
- charging the battery with a current with a charge current frequency which is higher than the battery electrolyte resistance frequency and lower than the battery charge transfer resistance frequency.
A system for charging a motor vehicle battery, comprising:
- means for determining the electrolyte resistance frequency of the battery,
- means for determining the charge transfer resistance frequency of the battery, and
- means for controlling the battery charge current and able to control the battery charging by a current with a frequency which is higher than the battery electrolyte resistance frequency and lower than the battery charge transfer resistance frequency.
