ECOtality’s Minit-Charger 12 opportunity charger avoids overcharging and extends the useful life of batteries by up to 40%. The algorithm delivers a fast charge while reducing the need for multiple spare batteries—potentially saving thousands a year. Patented algorithms allow a sustained charge of 250 DC Amps. The universal model works with all batteries, all battery capacities and voltages from 24-80 volts. The sequencing option reduces AC circuit requirements by 50% and creates the potential for a significant reduction in peak kW demand. It can charge sealed and flooded batteries.
