Servotech Power Systems has announced a major technological breakthrough with the granting of a new patent for a smart charging interoperability device that enables GB/T (Bharat DC001) electric vehicles to seamlessly charge using CCS2 fast chargers, the standard increasingly adopted across India’s expanding EV ecosystem.
The patented technology works like a smart adapter that connects a GBT-compatible EV to a CCS2 charging gun, letting older electric vehicles use the newer fast charging stations. This innovation is expected to significantly enhance charging flexibility, reduce infrastructure redundancy, and accelerate the transition toward unified national charging standards.
According to Servotech, the device has undergone successful field tests across EV bus fleets, commercial cabs, and other GBT-enabled vehicles, demonstrating reliable performance and full compatibility with CCS2 chargers. The company noted that as India phases out legacy GBT chargers in favor of the more advanced CCS2 architecture, the converter ensures existing fleets are not left behind.
Industry experts highlight that this technology can help increase utilization rates at CCS2 charging stations, reduce the need for dual charging networks, and cut deployment costs for operators. With thousands of GBT-standard EVs still operating across states, especially in public transport and commercial mobility, the device offers a practical bridge during India’s charging-standard transition.
The patent strengthens Servotech’s position in the EV charging market as a leading innovator in power electronics and sustainable mobility solutions. The company emphasized that widespread availability of the converter could support faster EV adoption, smoother charging infrastructure upgrades, and better interoperability across India’s rapidly growing EV landscape.
