Battery-as-a-service for Electric Mobility

India has about 330m* motor vehicles on its roads today, ~83% of which are two-wheelers (2W) and three-wheelers (3W), which have also been among the fastest growing segments over the past decade. Average trip lengths in India tend to be shorter than those in the developed world, primarily due to higher urban densities.

If we overlay these factors on the emerging EV market in India, we essentially see the need for a flexible, local ‘energy-as-a-service’ ecosystem – where smaller, more affordable EVs can get quick and convenient access to charging and swapping solutions. Battery swapping can offer a ‘re-fuelling’ experience similar to a petrol 2W. It takes only a few minutes and can be done manually for small vehicles as they have light batteries.

Battery Swapping: a consumer perspective

In battery swapping, a discharged battery in a vehicle is replaced with a charged one. The discharged battery is then separately charged in a controlled environment.

The Indian consumer is price-sensitive. Battery Swapping can help reduce upfront vehicle cost (capex) as well as operating cost (opex) as the EV, which is sold without the battery and hence is cheaper, relies on a swapping network for its operation. In this scenario, the total cost of ownership (TCO), a key driver of EV adoption in India, can be upto 50% lower than that of a fossil fuel-powered vehicle.

A typical 3W driver buys fuel (petrol or CNG) for INR 300-400/day and drives 100-150 km a day. Electric 3W operators will be able to rent a fully charged battery (2.5 kWh or 5 kWh) for Rs.120-150 and drive ~100 km.

Swap Station Economics  

The cost of setting up a battery swap station in India could range from Rs. 0.1 million for a station that can hold up to 20 small battery packs replaced manually, to Rs. 37 million for an automated one that serves cars and contains multiple large battery packs.

The Battery Swapping Market in India

The battery swapping operators in India currently serve the 2W and 3W markets. We expect these to remain the predominant markets for hyperlocal battery swapping in India. Our estimate of the annual market size for 2W and 3W battery swapping in India in 2025 is $5.78b.


 The role of technology in Battery swapping

  • Swap Station tech: connects different battery types with the swap-station for State-of-charge (SoC) assessment, inter-operability, and charging
  • Demand and Supply across swap stations: Data from the batteries & EVs on a swap operator’s network can predict upcoming demand and match it with availability of charged batteries.
  • Energy Pricing tech at swap stations: Technology can enable smart charging of batteries at off-peak hours to reduce energy costs.

Battery Swapping: Rethinking regulations

by Aditya Ramji

Battery Swapping serves as a trade-off between a larger battery (i.e. higher range & cost) and a cheaper EV (as the EV can be sold minus the battery). 

India needs greater policy support for the battery swapping industry

The fundamental definition of a ‘public charger’ will need to account for swapping stations, as it may be critical in deciding eligibility for government incentives on land, equipment, and tariffs. Electricity regulators and utilities will also have to reconsider regulations and incentives for battery swapping stations. 

Swapping operators need to factor in fixed costs of wiring or cabling similar to DC/AC fixed charging stations, given that they may require fast-charging in case of higher battery swap turnover. 

Battery swap at a local store

While stand-alone EV swap-stations can be monitored, power utilities would have to ensure separate meters and tamper-proof connections with lower tariffs for small-scale local swapping operators, as being envisaged for electric 2W & 3W.

While these are just a few considerations, battery swapping has merit in emerging market use-cases, and a streamlined ecosystem & regulatory framework will drive greater consumer confidence and design innovation in swapping models.

Asian Benchmarks in Battery-swapping

EV battery swapping for the two- and three-wheeler market is currently registering the highest growth rates in Asia-Pacific. We profile 2 leading players who have scaled up in this space.

Gogoro, Taiwan:

  • Gogoro is a leading battery swap provider and electric 2W maker, more than 400,000 riders and 2,100 battery swapping stations.
  • Known for its innovation in ultra-smart batteries and swapping stations for electric 2Ws.
  • In August 2021, the company surpassed 200 million battery swaps since its 2015 launch.
  • Together with its vehicle partners, Gogoro-powered vehicles account for nearly 97% of all electric scooters sold in Taiwan.
  • Strategic partnership announced with Hero MotoCorp, India.
  • Total funding raised: $480m.

NIO, China:

  • Founded in 2014, NIO started building smart vehicles & creating innovative charging solutions.
  • NIO’s suite of EV energy solutions include the NIO Power Swap (a 3min fully automatic battery swap), NIO Power Charger (for fast charging any EV) and NIO Mobile (portable power bank for a car)
  • As of July 2021, NIO had built 301 Power Swap stations in 59 cities across China and served about 800,000 battery swaps for its customers.
  • NIO aims to have 700 swapping stations by the end of 2021 and 4000 stations globally by 2025.
  • The automaker recently picked Norway as its first market after China, including its battery swap offering.
  • Total funding raised: $5.4b over 10 rounds.
