VEHICLE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240123854 titled 'VEHICLE
Simplified Explanation
The patent application describes a vehicle with a charging circuit that can convert AC power from an external power system to DC power to charge the vehicle's power storage device. The controller is programmed to monitor the impedance of the charging path during external charging and switch control of the charging circuit if the impedance exceeds a threshold value.
- The vehicle includes a power storage device for storing electrical energy.
- The charging circuit is capable of converting AC power to DC power for charging the power storage device.
- The controller is programmed to control the charging circuit.
- A detection circuit is used to monitor the impedance of the charging path during external charging.
- The controller switches control of the charging circuit if the impedance exceeds a threshold value during external charging.

Original Abstract Submitted
a vehicle includes a power storage device, a charging circuit capable of external charging by converting ac power from a power system to dc power and charging the dc power to the power storage device when the vehicle is connected to the power system external to the vehicle, and a controller programming to control the charging circuit. the vehicle includes a detection circuit configured to detect the impedance of the charging path from the power system to the power storage device during external charging. the controller is programmed to switch control of the charging circuit when the impedance of the charging path is higher than the threshold value during external charging, compared to when the impedance of the charging path is lower than the threshold value during the external charging.
