Their creation, Battery Smart, an EV battery tech startup, has rapidly ascended to become a pivotal force, currently orchestrating an astonishing 1 lakh battery swaps every single day across its extensive network. With a footprint spanning over 1,200 stations in more than 35 cities, this venture isn’t just participating in the EV revolution; it’s leading the charge in the battery-swapping domain.

Last month, on August 7th, this Delhi-based enterprise, born from the innovative spirit of Khurana and Sikka, celebrated a monumental achievement: surpassing one lakh daily battery exchanges facilitated through its network, serving over 55,000 drivers. Since its humble beginnings in June 2020 with the launch of its first swap station in Janakpuri, New Delhi, Battery Smart’s expansion has been nothing short of meteoric. They now boast over 45 million cumulative swaps, a testament to their rapid growth and market penetration.

Established in 2019, the core philosophy behind Battery Smart was to democratize EV adoption. Siddharth articulates their goal: to make electric mobility "simple, economical, and accessible through a unique partner-led model."

Bridging the Gaps: The Power of Swapping

Battery swapping technology emerges as a crucial answer to some of the most pressing concerns in India’s electric mobility sector: the hefty cost of EVs (where batteries can account for up to 40% of the production price), the glaring inadequacy of charging infrastructure, and the often-prohibitive time required to recharge vehicles.

In a country where the e-mobility sector is predominantly driven by two and three-wheelers – vital for public transit, freight, and last-mile deliveries – battery swapping offers a particularly elegant solution. Smaller vehicles necessitate lighter, easily swappable batteries. Furthermore, drivers of these commercial vehicles can ill afford to spend hours waiting for a charge. Swapping a depleted battery for a fully charged one in mere minutes translates directly into increased operational time and higher earnings, a boon for fleet operators and delivery personnel alike.

Pulkit Khurana, co-founder, sheds light on their journey, revealing that their venture recorded an impressive revenue of Rs 63.5 crore in the fiscal year 2023.

Having dedicated over a decade to the logistics and shared mobility sectors, and even dabbling in policy consulting before co-founding Battery Smart, Pulkit and Siddharth keenly observed the e-mobility landscape. They identified significant market deficiencies.

"When we began, we noted that over 2.5 million electric rickshaws in India, powering nearly 70 million people’s daily commutes, relied on lead-acid batteries. The high upfront costs presented a substantial barrier to EV adoption in a price-sensitive market like India," Pulkit recounts. He further elaborated on the recurring issue of lead-acid batteries requiring replacement every six months, coupled with the long charging times – 10-12 hours overnight and an additional 3-4 hours during the day. Their ambition was clear: to upgrade this existing system with superior technology. Battery swapping emerged as the definitive solution, effectively eliminating the need for end-users to own the battery, thereby slashing upfront costs by as much as 40%.

While many contemporaries were venturing into EV manufacturing or charger production, Pulkit and Siddharth strategically chose to focus on battery-swapping technology. "Manufacturing chargers and vehicles is exciting," Pulkit acknowledges, "but we prioritized tackling range anxiety, charging downtime, and high costs." Their approach involves partnering with over ten leading original equipment manufacturers (OEMs) specializing in battery development, allowing them to remain at the forefront of technological advancements and select the best available battery solutions.

The Mechanics of a Seamless Swap

Pulkit meticulously describes Battery Smart’s operational model: "We utilize interoperable batteries for electric two and three-wheelers. Users can effortlessly locate the nearest swapping station via the Battery Smart app. Our objective is to establish a dense network where EV users are always within a one-kilometer radius of a station, guaranteeing zero wait time." At these stations, EV users within the Battery Smart ecosystem can exchange their depleted battery for a fully charged one in under two minutes, with payments conveniently processed through the app.

Their "battery-as-a-service" model enhances EV ownership accessibility and affordability. By leveraging existing infrastructure through partnerships with small businesses and local shops, they rapidly expand their network, simultaneously providing additional income streams to their partners. This ingenious strategy has enabled them to penetrate Tier 1, 2, and 3 regions across India, areas often underserved by conventional charging infrastructure.

Battery Smart proudly asserts that its interoperable batteries cater to over 200 vehicle models with a single battery type. "The core idea," Pulkit emphasizes, "was to ensure a smooth transition for new users from internal combustion engine (ICE) vehicles to EVs. Battery swapping mimics the refuelling experience, allowing for a quick exchange of batteries. This simplicity and efficiency lead to greater time savings, longer travel distances, and increased incomes for drivers."

Siddharth confirms that a single swap typically costs between Rs 100 and Rs 150, offering a range exceeding 60 km. Users can also opt for various subscription plans tailored to their needs. "The vehicles are equipped with smart meters that indicate when a swap is needed, and the entire process – from locating a station to payment – is managed through the Battery Smart app," he adds.

Regarding their batteries, Pulkit explains, "We deploy smart, interoperable lithium-ion batteries compatible with electric three and two-wheelers. These are sourced from over 10 Lithium-ion battery OEMs in India, chosen for their proven track record in quality and reliability. While manufactured by different OEMs, their specifications and dimensions are uniform, ensuring a consistent swapping experience for the customer."

Building the Network: A Partner-Led Revolution

When it comes to establishing a swap station, Battery Smart’s partner-led model shines. "We leverage existing infrastructure and collaborate with local businesses, enabling us to set up swap stations at a rapid pace – sometimes three to four stations daily – without the need for commissioning new real estate," Pulkit proudly states.

The setup process typically takes six weeks for a station to become operational. Partners only pay a licensing fee, while Battery Smart handles all investments in chargers and batteries. This model allows partners to typically break even on their upfront fee within a year, with a standard three-year operating agreement. Through this expansive network of 1,200 swap stations, they now facilitate one lakh swaps daily.

Ensuring Compatibility and Safety

For a battery-swapping venture serving a diverse fleet of two and three-wheeler EVs, ensuring compatibility is paramount. "Our interoperable batteries serve over 200 vehicle models with a single battery type. While different OEMs produce them, the specifications and dimensions are uniform," Pulkit reiterates.

The swappable batteries typically have a capacity of 2 to 2.5 kWh and weigh between 12 to 15 kg. These lighter batteries contribute to lower vehicle weight, improved energy efficiency, and extended range. While electric two-wheelers generally operate with one battery, e-rickshaws and e-autos can accommodate up to two, depending on their energy consumption and range requirements.

Pulkit emphasizes their commitment to safety: "Our partner OEMs provide warranties and ensure performance and safety, and we conduct rigorous quality testing before deployment. We also invest heavily in developing robust Battery Management Software (BMS) technology, crucial for effectively managing swappable batteries."
