Abstract
A battery charger apparatus, system, method and computer product monitors changes and current and/or voltage to determine whether a hot disconnect event is occurring by monitoring changes in current and/or voltage over time and by providing a shutdown prior to arcing or early in the event based upon predetermined conditions representative of a hot disconnect, thus eliminating or significantly reducing the time and severity of the event.
Claims14
An integral anti-arcing battery charger hot disconnect system, comprising:
- a battery charger having a control board and charging leads and connectors;
- at least one of a current and a voltage sensor integrated with said charger and configured to indicate instantaneous current or voltage, respectfully over said charging leads, the at least one sensor provided integral to the charger, with sensor measurement at a point between a control board and charger connectors;
- a processor and nonvolatile memory configured to execute code, said code configured to define at least one of a current and a voltage threshold, measured by said one or more integrated sensors and triggering a charger shutdown.
A method for hot disconnection of an integral anti-arcing battery charger, comprising:
- providing a battery charger having a control board and charging leads and connectors;
- with at least one of a current and a voltage sensor integrated with said charger, measuring instantaneous current or voltage, respectfully over said charging leads, the at least one sensor provided integral to the charger, with sensor measurement at a point between a control board and charger connectors;
- with a processor and nonvolatile memory configured to execute code, executing said code to define at least one of a current and a voltage threshold, measured by said one or more integrated sensors and triggering a charger shutdown.
