1. A method for charging a battery, wherein the battery is a lithium-ion battery, the method comprising:

  • monitoring a current through the battery;

    monitoring a voltage of the battery;

    monitoring a temperature of the battery;

    inferring electrode lithium surface concentrations for the battery from the monitored current, voltage and temperature; and

    applying the charging current and/or the charging voltage in a manner that maintains the inferred electrode lithium surface concentrations for the battery within set limits.
