Electric cars may get same power specs


In a bid to standardise the various parts of the electric vehicle (EV) ecosystem, several constituents, including original equipment manufacturers (OEMs), have come together to define standards. The move is primarily aimed at commercial vehicles that will ply with swappable batteries.

OEMs like Mahindra & Mahindra, Lucas TVS, Okinawa, Kinetic, GEM, Ashok Leyland, Exicom, Amara Raja Batteries and Exide are involved in preparation of these specifications. “We have coordinated this effort and did iterations in the documents based on feedback from all different stakeholders,” said Prabhjot Kaur, CEO of the Centre for Battery Engineering and EVs (C-BEEV). The centre comes under the department of electrical engineering at IIT-Madras. The project is spearheaded by professor Ashok Jhunjunwala.

“We don’t want to commit the mistakes of mobile handset companies that did not standardise chargers, etc, when it would have made sense. We will continue to work towards setting up more common standards for the industry,” Kaur The standards are grouped under ‘Lock Smart - Vehicle Battery Charger Cloud Protocol’ (or LS-VBCC). They will act as the cornerstone for EVs. “The batteryswapping industry standard has been designed with a group coming from different segments — charger manufacturers, vehicle OEMs, battery manufacturers and other stakeholders,” Kaur said. The purpose of the standard is to promote interoperability between energy operators, vehicles, batteries and chargers.

“Using Esmito’s platform at C-BEEV in IIT-Madras and several other locations, we have done several three-wheeler and two-wheeler pilots using the standard swapping platform. Esmito is now offering this solution as a SaaS platform for energy/fleet operators,” Kaur said. For example, the standards will involve vehicle identification number (VIN) and battery identification number (BIN) in specified formats that will help identify where the parts were produced, including if the batteries are lead acid, lithium-ion or cobalt-based, among others.
