摘要:
A device and method for rated voltage detection and charging of electric batteries. The method comprises the steps of measuring a terminal voltage of the battery having first or second rated voltages, comparing the terminal voltage to a number of threshold voltages between a minimum threshold voltage and a maximum threshold voltage, determining a condition of the battery, which can be ready to charge or fault, based on a comparison of the terminal voltage to the threshold voltages, determining that the rated voltage of the electric battery is the second rated voltage if the determined condition of the electric battery is ready to charge, conducting a pre-charge process if the determined condition of the battery is neither ready to charge nor fault, determining the rated voltage of the electric battery based on a response to the pre-charge process, and charging the electric battery according to the determined rated voltage.
摘要:
A portable hand held power inverter/converter having a pass through device for simultaneously sourcing A.C. and multiple voltage D.C. power consuming devices through a single D.C. power source connection. Inverter and converter circuitry is provided to invert and convert D.C. voltage to an A.C. voltage source and a lower DC voltage. A.C. electrical outlets are provided to facilitate a connection to an external A.C. power-consuming device and a DC outlet to a lower volt DC power-consuming device. The pass through device provides an independent and simultaneous connection to an additional D.C. outlet that would otherwise be eliminated when occupied by the inverter thus allowing simultaneous connection and operation of both A.C. and multi source D.C power consuming devices through a single external D.C. power outlet of a single D.C. power source.
