Systems and methods for in-vehicle charging of pallet jack batteries

摘要

Systems and methods for in-vehicle charging of pallet jack batteries are provided. An example system allows using a power source of a host vehicle configured to provide power at voltage levels lower than the operating voltage of the pallet jack battery stack. The system may allow, for example, charging a 24 volts pallet jack battery stack from a 12 volts power source of the host vehicle. The system may further comprise an interconnecting circuit having a plurality of contactors electrically coupling the batteries in parallel for charging and serially for discharging. The system may further comprise a voltage monitoring circuit to detect whether the pallet jack is connected to the host vehicle power source for charging. Based on the detection, the voltage monitoring circuit may reconfigure the interconnecting circuit to electrically couple the pallet jack batteries in parallel.

1. A method for in-vehicle charging of a pallet jack batteries, the method comprising:
monitoring a voltage level of a power source associated with a host vehicle; based on the monitoring, configuring an interconnecting circuit associated with a pallet jack battery stack of a pallet jack to enable charging of the pallet jack battery stack at a voltage level of the power source associated with the host vehicle; electrically coupling the pallet jack battery stack to the power source; and charging the pallet jack battery stack from the power source.
