I don't know of any distinct advantage that electrovaya has regarding recharge times. That issue can get complicated and technical as it relates to the type of charger (eg; 120, 240v, etc.) as well as the attributes of the battery. Electrovaya had problems with the chrysler program when they pushed the limits of the battery returning power to the grid. They corrected that issue with the new 2.0 battery and the thermal properties of the battery were dramatically improved. Throughout the years that miljobil was working with Tata there were no reports of thermal runaway problems and their engineers had written papers on the prevention of thermal runaway. This was the main reason for the Miljobil aquisition, as well as other important patents. With the new 2.0 battery and then the 20% improvement to most parameters of the battery performance I would think that the recharge time would be competitive. That being said there are some batteries that have focused on recharge times and have improved them dramatically. My understanding of the physics involved are that even if the battery can receive a very rapid charge the charger needed to provide that much power is prohibitive economically, but I am no expert.
