Abstract
Controlling reverse in-rush current for vehicle chargers is provided. A system can include a controller to determine a first value of voltage. The voltage can be of or associated with a DC link of a charger to output power to a battery of an electric vehicle. The controller can detect an in-rush current from the battery to the charger. The detection can be responsive to the first value of voltage at the DC link being greater than a reference value of voltage established for the DC link.
Claims20
A system, comprising:
- a controller configured to:
- determine a first value of voltage at an input of a direct current (“DC”) link in a charger configured to output power to a battery of an electric vehicle;
- and
- detect, responsive to the first value of voltage at the input of the DC link being greater than a reference value of voltage established for the DC link, an in-rush current from the battery to the charger.

A system, comprising:
- a controller configured to:
- determine a first value of voltage at an input of a direct current (“DC”) link in a charger configured to output power to a battery via a capacitor;
- and
- control, responsive to a comparison of the first value of voltage at the input of the DC link with a reference value of voltage established for the input of the DC link, voltage at the capacitor.

A method, comprising:
- determining, by a controller, a first value of voltage at an input of a direct current (“DC”) link in a charger configured to output power to a battery via a capacitor;
- and
- controlling, by the controller, responsive to a comparison of the first value of voltage at the input of the DC link with a reference value of voltage established for the input of the DC link, voltage at the capacitor.
