  • Publication number: 20140028249
    Abstract: A system for pulse charging a battery includes a battery module, an inverter, and a pulse apparatus connected to the inverter and the battery module and configured to pulse charge the battery module by modulating a power output from the inverter. A method of pulse charging a battery module includes the steps of converting AC power output from a power grid to constant DC power, modulating the constant DC power to produce modulated power, and providing the modulated power to the battery module to pulse charge the battery module.
