Abstract
Disclosed herein are a rechargeable battery jump starting device with a control switch (e.g. rotary control switch) and an optical position sensing switch system to determine a position of the control switch. The optical position sensing switch system includes an optical position sensor using optical coupling to insure an integrity of isolation on a 12V to 24V master switch to allow for a safe and effective operation, and configured so that a microcontroller unit reads a position on the master switch.
Claims20
A rechargeable battery jump starting device having an electrical optical position sensing switch system, the device comprising:
- a first battery;
- a second battery;
- an electrical control switch electrically connected to the first battery and second battery, the electrical control switch having a parallel switch position for connecting the first battery and second battery in parallel, the electrical control switch having a series switch position for connecting the first battery and second battery in series;
- a microcontroller unit electrically connected to the electrical control switch;
- and
- an optical coupler electrically connected to the electrical control switch, the optical coupler providing a signal to the microcontroller for indicating the position of the electrical control switch.
A rechargeable battery jump starting device having a position sensing switch system, the device comprising:
- a first battery;
- a second battery;
- a switch electrically connected to the first battery and the second battery, the switch having a first switch position for connecting the first battery and second battery in parallel for outputting a first voltage, the switch having a second switch position for connecting the first battery and second battery in series for outputting a second voltage;
- and
- a sensor configured to generate a signal indicative of the position of the switch.
