The Yin and Yang of Swapp's Battery-as-a-Service

Swapp Design offers the smartest BaaS solution for 4W EVs in India. For an efficient BaaS model, the 'battery' and the 'service' elements must work in complete harmony - like the yin and the yang. For this reason, at Swapp Design, the design of the battery system and the swapping station are tailored to work together in sync.


A. The 'smart' station design helps the battery have a long life.

B. The 'sleek' battery design helps the station reach higher efficiency.



A. The 'smart' station design helps the battery have a long life.

  • Charging at a controlled rate: The rate of charging of a battery system plays a crucial role in the degradation of the battery over time. The faster we charge a battery system, the sooner it reaches the end of life. Our station ensures that the battery is charged at a controlled rate, extending its lifespan and optimizing its performance. Therefore, the station helps the battery live longer and ensures EV users receive reliable performance from their vehicles.

  • Controlled environment: Thermal management also plays a significant role in the longevity of the battery system. At our stations, battery modules are stored and charged in a controlled environment. This proactive approach to battery management helps maintain the battery in optimal condition, maximizing its efficiency and reliability.

  • Battery cleaning mechanism: Our swappable battery packs are bottomless. So, when the battery returns to the station, its surface often has dust, dirt, or other contaminants. Our station includes a battery-cleaning mechanism that keeps the battery clean while it is in the station. This helps to minimize battery degradation over prolonged use.

  • Proactive battery retirement: Aging batteries that reach the end of their usable life in the automotive application are flagged and taken out of circulation for a second life utility. This includes repurposing old battery cells for other applications and reusing other 'healthy' subcomponents. This circular economy approach minimizes waste and maximizes the value of the battery, reducing the environmental impact.


B. The 'sleek' battery design helps the station reach higher efficiency.

  • Frictionless swapping: Conventional under-chassis battery swapping methods are inconvenient and cumbersome. They involve parking the EV precisely at a designated location, the occupants exiting the EV, and lifting the EV to provide access to the jig for swapping under the chassis. On the other hand, the process at our stations is frictionless. Why? Because the battery system is sleek, such that the ground clearance of the EV is adequate for the act of swapping. This enables each station to cater to multiple EVs quickly and simultaneously, maximizing the throughput.

  • Simple and efficient stations: Since our station does not need to lift the EV, its design is simplistic and minimalistic. This also reduces the energy consumption at the station, promoting operational efficiency and sustainability.

  • Modular design: Our battery system is modular, which means that instead of swapping a ~300kg battery pack, the station swaps a set of ~30kg modules. This avoids the need for expensive and complex jigs or robotic arms. Automated Mobile Robots (AMRs) are utilized to automate the swapping process, further optimizing the station's operational efficiency. Additionally, the modular battery system leads to high interoperability. This means the same station can utilize the same infrastructure to cater to different EV models.


The above narrative illustrates our approach to BaaS and how the battery and the station work in complete harmony - like the yin and the yang. Together, our battery and swapping station promotes a circular economy approach, minimizing waste and maximizing the value of the battery, contributing to a more sustainable future for the EV industry in India. Experience the future of BaaS with Swapp Design - where innovation meets sustainability!
