Abstract
Rechargeable batteries, charging methods and systems for fast charging of the battery under all environmental temperatures and without causing battery degradation are disclosed. A charging control system for charging a rechargeable battery can include an ohmically modulated battery, a temperature sensor configured to monitor a temperature of the battery: a switch that can electrically engage the battery to a source of electrical current through either a low-resistance terminal or a high-resistance terminal of the battery: and a controller electrically connected to the temperature sensor and the switch and that can receive input from the temperature sensor and is programmed to determine whether to electrically engage the battery to the source of electrical current through either the low-resistance terminal or the high-resistance terminal through the switch based on input from the temperature sensor.
