Abstract
Embodiments disclosed herein provide methods and systems for auto-voltage detect chargers. One disclosed method comprises the steps of determining a condition of a battery based at least in part on a measured response to a predetermined test charge; and determining a voltage rating of the battery based at least in part on the condition of the battery and a response to a precharge process.
Claims23
A method of auto-voltage detection, comprising:
- determining a condition of a battery based at least in part on a response to a predetermined test charge;
- and
- determining a voltage rating of the battery based at least in part on the condition of the battery and a response to a precharge process.
A method for auto-voltage detection comprising:
- applying a predetermined test charge to a battery;
- measuring the initial terminal voltage of the battery in response to the predetermined test charge;
- determining a condition of a battery based at least in part on the voltage response;
- applying a first predetermined precharge current to the battery for a first predetermined period of time;
- waiting a second predetermined period of time;
- applying a second predetermined precharge current to the battery for a third predetermined period of time;
- waiting a fourth predetermined period of time;
- determining a voltage rating of the battery based at least in part on the condition of the battery and a measured response to a precharge process;
- and
- charging the battery based at least in part on the voltage rating of the battery.
7 more elements
A system for auto-voltage detection comprising:
- a battery charger, and
- a microprocessor in communication with the battery charger and configured to determine a condition of a battery based at least in part on a measured response to a predetermined test charge, and further configured to determine a voltage rating of a battery based at least in part on the condition of the battery and a response to a precharge process.
