Abstract
Techniques and systems are described that enable multiple current source prioritization with overvoltage protection.
Claims20
A multiple current source prioritization circuit that prevents a battery from charging to a voltage above a first voltage setpoint for a first voltage regulator, comprising:
- a first input configured to interface to an alternator coupled to the first voltage regulator;
- a second input configured to interface to a solar panel, the second input having a current regulator;
- a first output configured to interface to the battery having a charge/discharge current and to a load having a load current;
- a first circuitry configured to detect that the alternator is in a first state, the first state corresponding to the first voltage setpoint for the first voltage regulator;
- and
- a second circuitry configured to:
- when the first circuitry represents that the alternator is in the first state,
- set the current regulator to a first constant current value below the load current, wherein:
- a first current at the first output includes an amount of current from the solar panel corresponding to at least the first constant current value.

A method of operating a multiple current source prioritization circuit that prevents battery overcharging, the method comprising:
- detecting, by a first circuitry, the output of an alternator interfaced through a first input;
- providing, by the first circuitry, the detected output of the alternator to a second circuitry;
- determining, by the second circuitry, that the alternator is in a first state, the first state corresponding to a first voltage setpoint for a first voltage regulator for the alternator;
- configuring, by the second circuitry, in response to determining that the alternator is in the first state, a current regulator to a first constant current value below a load current, wherein:
- the load current is interfaced through a first output, the first output being interfaced to a battery having a charge/discharge current and to a load having the load current, and wherein the current regulator is interfaced through a second input to a solar panel;
- and further wherein:
- a first current at the first output includes an amount of current from the solar panel corresponding to at least the first constant current value.
