  • Patent number: 9461496
    Abstract: A method and system for recharging a solid state battery device. The method can include providing the solid state battery in a fully or partially discharged state. The solid state battery can be coupled to a pair of electrodes. An energy source coupled to the electrodes can be used to supply energy to the solid state battery. This supply of energy can use a first constant current recharge process followed by a constant voltage recharge process. This supply of energy can cause an increase of an energy level of the solid state battery to the maximum energy level within a predetermined amount of time. The predetermined amount of time can be determined as being less than a time period associated with recharging the solid state battery using solely a constant current recharge process.
