As India looks to accelerate the adoption of Electric Vehicles, batteries & issued related to batteries may play the most important role in deciding the future. The draft ‘Battery Swapping Policy’ of the NITI Aayog becomes an important policy in this context. Here is what the policy contains. India is the fourth-largest greenhouse gas emitter and third-largest CO emitter in the world. Among the sectoral composition of CO emissions, transportation stands as the third biggest contributor. More than 50% of this sector‘s emissions come from 2 & 3 wheelers and cars alone. Further, the transport sector is projected to be among the fastest-growing sources of carbon emitters. However, India still does not have a long-term strategy to make this sector consistent with the goals of the Paris agreement. Having made significant progress in renewable energy generation capacity, India had pledged to become net-zero by 2070. While this transition requires a multi-sectoral approach, the widely accepted strategy for the transport sector is the electrification of transportation. Accordingly, India adopted the National Electric Mobility Mission Plan (NEMMP), 2020, which aimed to increase the fleet of electric/hybrid vehicles to around 7 million by the year 2020. As a part of this mission, Faster Adoption and Manufacturing of Hybrid & Electric Vehicles (FAME-1 and FAME-2) were adopted. However, the adoption of Electric Vehicles(EVs) has not happened at the anticipated pace. EVs are a nascent but fast-growing industry in India. In 2021, more than 3 lakh electric vehicles were sold which is more than double the number in 2020. EVs suffer from a range of issues, starting from ‘range anxiety’ to the ‘right to repair’. Providing meaningful solutions to these challenges could further drive the adoption of electric vehicles as the primary mode of transport. This story looks at one of those plausible solutions that have the potential to spur the growth of adoption of EVs– ‘Battery as a service’ or ‘Battery Swapping’. We discuss NITI Aayog’s recently released ‘Draft Battery Swapping Policy’ in this story. What is Battery Swapping? In simple terms, battery swapping is a mechanism that enables the de-linking of the charging and the battery, thereby providing users with the flexibility to exchange the discharged batteries with charged batteries. This is aimed to minimize the charging downtime as well as to provide users more convenience in faster adoption of EVs. Battery swapping has several advantages, some of which are, That being said, battery swapping also comes with the following challenges that could become roadblocks to the mass adoption of EVs. To address these challenges and to enable mass-scale adoption of EVs, India’s premier think-tank, NITI Aayog has come up with a draft battery swapping policy. This was earlier announced by the Finance Minister in her budget 2022 speech. The scope of this policy is limited to light electric power train vehicles (LEV) of category L, and E-rickshaws/E-carts. However, the government can expand this scope to other segments of EVs. The draft policy address cross-sectoral issues like the financing, technical specifications and requirements, scope of regulatory mechanisms, and better lifecycle management of batteries. The following sections deal with these aspects in detail. Technical & operational requirements: Interoperability plays a key role in determining the success of battery swapping. Interoperability is nothing but the compatibility of the batteries with the components of electric equipment of different EVs. This can be made easier if adequate standardization is ensured across the whole EV ecosystem. Standardization of technical parameters as well as the performance standards is the need of the hour. Caution must be exercised to make sure that this standardization does not destroy the innovation and prevent efficient alternatives in the future. Some key requirements as mentioned in the draft are as below: Infrastructure standards: Data sharing and communication: Data forms an important element in the battery management cycle. Hence, proper standards for communication that are approved or defined by BIS must be deployed, and an open standard communication protocol such as Open Charge Point Protocol (OCPP) could be adopted. In addition to this, data-sharing agreements between battery providers are encouraged to provide better insights into the battery health and performance. Regarding the data tracking, only such data which is pre-defined is to be tracked by the providers and the government agencies have the authority to access them at any time. Considering the privacy of the users, a non-restrictive guideline shall be developed for the adherence of industry players.
