Abstract
Systems and methods for heating a battery, which may be performed alone or in combination with charging or discharging a battery. In some implementations, heating involves applying an alternating current waveform, which may be sinusoidal, to a battery. In some implementations, the heating signal is applied at a frequency and/or current with little or no net charge to the battery.
Claims20
A method of heating a battery comprising:
- generating a repeating signal to apply to a battery, the repeating signal having first portion and a second portion over a period, the first portion defining a leading edge rising to a body portion terminating in a falling edge, the second portion comprising an alternating current following the falling edge of the first portion, and
- wherein a frequency of the alternating current is selected to be between 2 kHz and 1 MHz.
A method of heating a battery comprising:
- generating a repeating signal to apply to a battery, the repeating signal having first portion and a second portion over a period, the first portion defining a charging portion terminating in a falling edge, the second portion comprising an alternating current following the falling edge of the first portion, and
- wherein a frequency of the alternating current is based on at least one of a conductance response or a susceptance response.
