Circuits and methods for heating batteries in series using resonance components in series
First Claim
1. A circuit for heating a first battery and a second battery, the circuit comprising:
- the first battery including a first damping component and a first current storage component, the first damping component and the first current storage component being parasitic to the first battery;
the second battery including a second damping component and a second current storage component, the second damping component and the second current storage component being parasitic to the second battery;
a first switch unit;
a second switch unit;
a switching control component coupled to the first switch unit and the second switch unit; and
a charge storage component;
wherein;
the first battery, the first switch unit, and the charge storage component are connected to form a first charging and discharging circuit; and
the second battery, the second switch unit, and the charge storage component are connected to form a second charging and discharging circuit;
wherein;
the switching control component is configured to turn on the first switch unit and the second switch unit alternately so as to control a first current flowing between the first battery and the charge storage component and a second current flowing between the second battery and the charge storage component; and
the circuit for heating the first battery and the second battery is configured to heat the first battery and the second battery by at least discharging the first battery and discharging the second battery.
