Could battery swapping be a greater resolution for electrical scooter in India? That’s the query after a sequence of fires reported in electrical scooters throughout manufacturers. While the precise motive for the fires isn’t identified, most corporations are shifting the blame on poor charging practices by shoppers. And that is exactly why some EV producers in India desire battery swapping as an alternative of residence charging.
In easy phrases, charging an EV works identical to it does with some other digital machine like a laptop computer or a cell phone. It might be finished at an EV charging station as nicely. But in case of battery swapping, because the person’s automobile battery is discharged totally or about to be discharged, producers or a third-party supplier simply swaps it out with a fully-charged battery at a battery-swapping station.
Companies declare customers usually would spend across the similar time ready for his or her batteries to get replaced as they must fuel-up a automobile. However, the problem can be the restricted places the place this facility can be accessible.
“With battery swapping, one of many key components of EV, charging is in full management of the swapping firm. The buyer by no means has to cost the battery. It is the service supplier that fees the battery packs,” Arun Sreyas, co-founder and CEO of RACEnergy, a battery swapping firm, stated by way of an electronic mail.
RACEnergy is presently piloting its service in Hyderabad and Tirupati. According to Sreyas, the corporate additionally cools their batteries earlier than charging and after charging.

“The second advantage of swapping is that there is always an extra pool of batteries that enables the swap to happen. This extra pool of batteries gives us ample time to charge the batteries and hence we are in no rush to fast charge. In fact, with our proprietary variable charging rates, we can slow down the charging as much as possible. This ensures that we utilize every available minute to reduce the rate of charging,” Sreyas added.
Another EV fleet participant which depends on battery swapping is Bounce. The firm can also be a Battery as a Service (BaaS) supplier. The firm’s CEO Vivekananda Hallekere had tweeted in response to the EV hearth reviews that to date Bounce is servicing over 3,000 swaps per day, which is roughly 180,000 km. The firm claims to have finished over 1,000,000 swap up to now two years for 20,000 prospects.

Hallekere advised indianexpress.com that there are a number of facet that might influence a scooter’s battery well being and result in a hearth. “There are many things that could go wrong with electric scooters: cell quality, cell packing, electrical wiring, battery management system and charging technology,” Hallekere stated.
Battery care can’t be the shopper’s job, Hallekere stated, including that there are different the explanation why battery swap is nice. “Fast charging ends in cells getting heated up. Batteries are charged at 0.5C. The cells usually are not being broken. One of the most important advantages is that there is no such thing as a quick swapping,” he identified.
On what may trigger fires in EVs, Hallekere added that the best way a battery is packed can also be actually essential. “It must be finished rather well with science and logic. If the house between the cells isn’t deliberate or if they don’t seem to be balanced it may trigger points like fires,” he stated.
There are additionally considerations the place quick charging could also be an issue for EVs, given this could warmth up the battery considerably. According to Bounce, that is the place the position of sensible chargers is essential. These can enhance, lower or cease the cost price primarily based on knowledge and be certain that the batteries do not overheat.
“Charging primarily based autos must be designed in a means as to make sure that the shopper should not have to fret. For instance, the Battery Management System (BMS) ought to be capable to talk with the sensible chargers in order that charging might be minimize off if battery temperatures attain harmful ranges or if battery well being is being affected,” Hallekere defined.
Bounce claims it doesn’t depend on any quick charging for this precise motive given it may influence the “health of the battery by making the battery behave erratically and this could adversely impact the thermal management.”
There’s little doubt that as EVs acquire reputation in India, questions on security will stay. As far as battery swapping goes, it is perhaps a very good resolution to keep away from EV fires, but it surely may also show to be an inconvenient one for normal shoppers, particularly those that purchased an EV for private use.
However, corporations resembling Bounce are assured these options will see adoption from EV customers. There’s additionally little doubt that the fuel-like comfort of BaaS options makes them extra applicable for different public transport modes resembling e-rickshaws in Delhi, lots of which already make the most of battery swapping know-how.
