Battery heating circuits and methods using resonance components in series based on current limiting and voltage inversion with bi-directionality and common inductance

摘要

Circuit and method for heating a battery. The circuit includes the battery including parasitic damping and current storage components. A first switch unit and first charge storage component are parts of a battery discharging circuit. A second current storage component is in series with the first charge storage component and a one-way semiconductor component. The one-way semiconductor component and second current storage component are in parallel with the first switch unit. The first charge storage component, second current storage component, and the one-way semiconductor component are parts of a battery charging circuit. A second switch unit is in parallel to the first charge storage component and the second current storage component. The second switch unit and the second current storage component are parts of a voltage regulation and polarity inversion circuit for the first charge storage component. The circuit heats the battery by discharging and charging the battery.
