Tata Power Charging Solutions, the largest provider of EV charging in the country, is looking at an over 6-fold jump in the number of semi-public and public chargers it offers for electric vehicles (EVs) to 25,000 from the current 4,000 over the next 5 years. The service provider is encouraged by the sharp month-on-month jump in the number of registered users on its mobile application amid a fast adoption to EVs, said a company executive.
