Imagine a FUTURE where…

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

Pushing the Frontiers

The future of mobility is electric and the core team behind SUN Mobility, have been involved in designing innovative solutions for Electric Vehicles (EV) and clean energy for more than two decades. 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.

Electric vehicles - 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

Electric vehicles are substantially more expensive than Internal Combustion Engine (ICE) vehicles because of the battery cost

Long charging time

Long charging

Currently, electric vehicles can be regular-charged in 8 hours and fast-charged in 1 to 2 hours. However, both options are still long-drawn

Equivalent infra


ICE vehicles have a strong, supportive refueling infrastructure; a similar charging infrastructure for EVs is not widespread

Range Anxiety

Range Anxiety/
Limited Range

The fear that electric vehicles will not meet the range of varying driving conditions

Shaping the future of mobility

A global energy solutions provider, we develop customised solutions for India's changing mobility needs.

The challenges in India's urban transportation are unique and hence 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 – 2/3 wheelers, cars and buses. This Made in India designed solution also tackles for the first time, the four main roadblocks hindering mass EV adoption - high costs, lengthy charging time and range anxiety.

Our business model separates the battery from the vehicle making EVs financially viable for the first time. Our 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 and integrated 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 impact urban transportation tying in with our vision to transit to a sustainable world.

The 3 key 'SMARTS' that differentiate SUN Mobility

A complete SMART MOBILITY ecosystem


The batteries are light-weight, long-life, compact and swappable
They are connected to the Smart Network that optimises battery health. It is also upgradeable
Modular and flexible, batteries are adaptable to multiple vehicle platforms


Fast refueling
Fast refueling
The batteries can be swapped in just a few minutes; faster than refueling 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


Pay-as-you-go model
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 & Intelligent
It monitors the battery and station, which are IoT enabled and linked to an app. It provides real-time feedback to customers and fleet owners

Our Partners in Sustainable Mobility

As enablers of mass adoption of electric mobility in the country, we are collaborating with different partners such as major state and city transport undertakings, fleet operators, shared mobility solutions providers and OEMs across diverse platforms- 2/3 wheelers, cars and buses - to provide an affordable, convenient and smart solution. This solution is poised to impact the way people commute in the future.

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

Our first partner, Hinduja’s flagship firm, Ashok Leyland

In record-breaking time (seven months), we have together created a first-ever solution for the world

We entered into a strategic partnership with Ashok Leyland to leverage our individual strengths and offer global solutions for mass adoption of electric mobility.

This alliance was sealed seven months ago in the backdrop of the government’s vision to go completely electric by 2030.
Ashok Leyland, known for being a pioneer of state-of-the art technologies and innovative alternative fuels in the automotiveindustry, is now focusing on designing tailor-made solutions for the EV market. They have now built a one-of-its-kind e-bus – Circuit-S – to match the country’s unique transport needs, that is powered by our swappable Smart Battery™ technology.

For the first time, our partnership makes mass adoption of electric buses possible since they are convenient, economical and scalable. This Circuit-S bus ranges from 9m to 12m, uses light-weight, small batteries which are quickly interchangeable, and requires less maintenance and provides more passenger room.

The advantages
for customers



The 'Smart Mobility' solution is economical because by separating the battery from the vehicle, you only pay for the energy used, similar to the current diesel system (Pay-as-you-go model)


The swap takes a few minutes; faster than any other available electric recharging/ diesel refuelling method


The Quick Interchange Stations are modular and can be installed on demand across India

Multi-platform compatibility

The 'Smart Mobility' solution is compatible across multiple platforms, from 9m to 12m buses

Small and light batteries

The Smart Batteries are 1/4th the weight; thereby, making them more efficient and freeing up space for 20 – 30 additional passengers

“At Ashok Leyland, we have always proudly leveraged Indian engineering and innovation to develop world-class solutions. Our partnership with SUN Mobility is yet another step towards bringing world-class solutions to India, developed in India, and by Indians. We are proud of this partnership and hope to bring several new innovative products to the market at the earliest.”
