SUN Mobility and SmartE partner to transform EV adoption in the country

Imagine a FUTURE where…

Urban transport is run entirely on renewable energy, making travel lighter on your pocket, time saving and conscience.
Mobility is fuelled by smarter solutions that are economically feasible and not reliant on subsidies.
We can live and breathe a cleaner, less polluted world for ourselves and future generations.

Pushing the Frontiers

The core team behind SUN Mobility is involved in designing innovative solutions for Electric Vehicles (EV) and clean energy for more than two decades to create a fully electric mobility ecosystem. We have leveraged our vast knowledge and experience acquired from working with fleet operators, shared mobility providers, state transport undertakings, and, automotive OEMs to create viable, scalable, economical, cleaner and, smarter mobility solutions for the world.

EVs - long considered to be an alternate solution to the urban mobility crisis - have not been adopted on a large-scale due to deterrents such as:

High upfront cost

High cost

The battery cost of EVs make them substantially expensive than Internal Combustion Engine Vehicles.

Long charging time

Long charging

EVs normally take 8 hours to charge and upto 1 to 2 hours for a fast charge. However, both options are still long drawn.

Equivalent infra


ICE vehicles have a strong supportive refuelling infrastructure; a similar charging infrastructure for EVs is not widespread.

Range Anxiety

Range Anxiety/
Limited Range

Concerns around EVs not being a fit for varied driving conditions.

Shaping the Future of Mobility

We develop customised solutions for India's changing mobility needs.

The challenges in India's urban transportation are unique and require a tailor-made solution. As specialists in the field of electric mobility and renewable energy we have created an open-architecture, 'Smart Mobility' model deployable across multiple vehicle platforms – 2 and 3 wheelers, cars and buses. This "Made in India" solution tackles four main roadblocks in mass EV adoption like high costs, long charging time, equivalent infrastructure, and range anxiety.


Our business model separates the battery from the vehicle making EVs financially viable for the first time. The modular Smart Batteries™ are smaller, lighter, and swiftly swappable confronting long-charging time. The strength of our intelligent and connected batteries along with our Quick Interchange Stations Network, creates a convenient refuelling infrastructure, faster and cheaper than existing petrol and diesel pumps for ICE vehicles.

Our Quick Interchange Station™ too are easy-to-install, require limited space, and work on a pay-as-you go model. This interconnected, intelligent system powered by renewable energy will be tracked by a Smart Network. This end-to-end solution accelerates the mass adoption of EVs for the first time and is a step closer to our vision to transit urban transportation to a sustainable world creating an impact.

Our quick interchange station for 3 and 2 wheelers is modular, intelligent and connected. The QIS is multi-platform compatible for E-bike, E-auto and an E- rickshaw. It allows the vehicles for a quick swap in 1-minute. The station is easy to use you can just swap the battery with a fully charged smart battery with minimal waiting time. The QIS supports digital payments on a pay-as-you-go basis. Our quick interchange station are convenient and easy to install. Read More

SUN Mobility Key Differentiators

Smart Batteries™

The batteries are durable, compact, and light-weight which makes them swappable.
Connected to the Smart Network optimizes the battery health which makes them upgradable.
Modular and flexible, batteries are adaptable to multiple vehicle platforms.

Quick Interchange Stations™

Fast refueling
Fast Refuelling
The batteries can be swapped in just a few minutes; faster than refuelling vehicles.
The swapping station has integrated charging and thermal management, ensuring batteries are always available.
Optimised real-estate
Optimised Real Estate
The modular and flexible station can be set up in a day and require 10-20 times lesser space to charge electric vehicle fleets.

Smart Network

It operates like the current fossil fuel-based system where you pay only for the energy you use. The payment system is completely digitally enabled.
The network detects the batteries state of charge and automatically locates the closest station.
Secure and Intelligent
It monitors the battery and station, which are IoT enabled and linked to an app. The Smart Network provides real-time feedback to customers and fleet owners.

Our Partners in Sustainable Mobility

Our partnership with various OEMs gives them a winning edge in many ways. By separating the battery from the vehicle, electric vehicles become cost-neutral for the first time as compared to the Internal Combustion Engine (ICE) vehicles. Additionally, our Smart Battery™ technology integrated to a network of Quick Interchange Stations™, supports a fast refuelling infrastructure that is faster and more convenient than any other available option at electrical charging or petrol and diesel stations.

We look forward to working with Automotive OEMs, Energy and infrastructure providers, Fleet operators and Smart Cities to accelerate electric vehicle adoption. Do reach out to us at
