A Layman’s Guide to Battery Swapping

Going through the process of charging a battery could be time-consuming.Instead, there exists a solution that makes the procedure of refuelling your EV much faster – mechanically swapping the discharged batteries with fully charged batteries.This activity is carried out at a Battery Swapping Station (BSS), where the discharged batteries are either charged or collected to charge at a central hub.

The swapping station acts as an aggregator providing the foundation & infrastructure where a number of batteries are made available to the EV user. This addresses a potential EV consumer’s concerns regarding the range of the vehicle.

Accessible swapping infrastructure would increase user convenience and build a greater confidence level. Considering the fact that it’s quicker than charging while helping prolong battery life, unlike multiple DC fast charging cycles.

Yuvraj Sarda, Head of Strategy at Sun Mobility, says that for individuals travelling large distances occasionally, the ability to charge anywhere without potential delays will be of utmost value.

In 2009, Better Place, an Israeli Battery Swapping start-up, raised nearly $850Mn, piggybacking on the boom of clean-tech investing. Within four years, the company went bankrupt. Shocked? So were we when we read about it. Now that we’ve understood the basics of battery swapping, let’s try and understand the challenges associated with Battery Swapping.

Challenges Associated with Battery Swapping

Huge Fixed Costs: The initial cost of setting up a Battery Swapping station is relatively high. This would include expensive electronics equipment & machinery to support the swapping infrastructure along with an additional buffer of batteries.

Tech Disruptions: Many organizations like Exponent Energy & Log 9 materials have come up with fast charging solutions where you could charge the EV within 15 minutes.

Standardization of Batteries: Many electric 2 & 3 Wheeler manufacturers believe in having a unique battery design to ensure competitive advantage in this space. For battery swapping to become the norm, the standardization of batteries is critical to support interoperability.

“Having been in the thick of all things battery swapping, we can say it is still very early to introduce an interoperability standard for an industry-wide implementation,” said Arun Sreyas, a co-founder of EV infrastructure company RACEnergy.

Scalability concerns: Naveen Munjal, MD Hero Electric, believes that the only way to make swapping work would be to have an extremely dense network. At this moment, there is a dearth in the number of swapping stations in India.

However, despite these challenges, we see major market players like Bounce betting big on the Battery as a service model. There are a couple of major reasons for the same:

— Negligible downtime – You could potentially swap a battery within 5 minutes, thus reducing downtime & improving ease of commute.

— Reduction in upfront cost –  Battery as a service model would significantly downsize the cost of buying an EV as battery ownership would be replaced by battery leasing. For a cost-sensitive market like India, affordability would be a major influencing factor to promote the adoption of EVs.
