Rechargeable battery jump starting device with depleted or discharged battery pre-conditioning system

Abstract

A rechargeable battery jump starting device with a discharged battery pre- conditioning system to facilitate boosting the discharged battery to jump start a vehicle or equipment engine. The pre-conditioning increases the operating voltage to the discharged battery during the pre-conditioning phase.

24 claims: 2 independent, 22 dependent

  1. 1
    A rechargeable battery jump starting device with a discharged vehicle battery pre-conditioning system, the device comprising:a 12V or 24V power supply;a supplemental power supply to increase voltage of the 12V or 24V power supply, wherein the 12V or 24V power supply and the supplemental power supply are configured as separate battery packs;and a discharged vehicle battery pre-conditioning system comprising a microcontroller unit and a resistor, the resistor being configured to provide controlled impedance and the microcontroller unit being configured to switch in the supplemental power supply with the 12V or 24V power supply for increasing an operating voltage during a pre-conditioning stage of boosting a discharged vehicle battery, wherein the pre-conditioning stage lasts until the supplemental power supply has emptied its charge into the discharged vehicle battery, and the supplemental power supply is not switched in with the 12V or 24V power supply during a subsequent jump starting stage;and a device for connecting the rechargeable battery jump starting device to the discharged vehicle battery for jump starting the vehicle engine.
  2. 14
    The rechargeable battery jump starting device according to any one of claims 1 to 13, wherein the discharged vehicle battery pre-conditioning system comprises a controlled impedance circuit comprising a current limit module, cable impedance and switch impedance.
  3. 15
    The rechargeable battery jump starting device according to any one of claims 1 to 14, wherein the rising voltage of the discharged vehicle battery is used to automatically turn off the pre-conditioning stage.
  4. 16
    A rechargeable battery jump starting device, comprising:a first 12V battery;a second 12V battery;a supplemental power supply;a first switching circuit electrically coupled to the first and second 12V batteries and configured to select the first 12V battery and/or the second 12V battery to provide either a 12V operating voltage or a 24V operating voltage;and a second switching circuit for switching in the supplemental power supply with the first 12V battery and/or the second 12V battery for increasing the 12V operating voltage or the 24V operating voltage for jump starting a depleted or discharged vehicle battery.
