The Express insulated gate bipolar transistor (IGBT) fast chargers are designed for heavy-duty electric vehicle fleet applications. The systems can charge 12 to 80 volt industrial lead acid batteries at currents of up to 640 amps, bringing a battery from 30% to 80% state of charge in approximately 1.5 hours, depending on battery size. The TwinMAX® is the only dual fast charger that allows you to simultaneously charge two batteries at rates up to 500 amps each. Its multi-voltage, multi-amp hour, high frequency design can grow with your needs while providing: low infrastructure cost, high efficiency rating, stands, cables and everything you need right out of the box. Drivers simply drive up and plug in - the TwinMAX charger does the rest, automatically keeping your battery fleet charged and equalized. Express fast charging saves you money by eliminating the need for truck battery changes so that multi-shift operations are able to run on one battery. This translates to higher labor productivity, energy savings and more manufacturing floor space for a quick ROI.
