I think instead of LNG it's wrongly mentioned as LPG. As per the article fuel saving is roughly 8 cents per km (INR 7 per km) which may not suffice in India. In absolute terms will see traction if power cost charged by swapping station is in the order of Rs.12 to 13 per kWhr. Challenge is even public charging stations struggle to offer this rate in most of the locations
Swappable batteries require a huge upfront investment. It is likely only feasible in China where a battery manufacturer can deploy the needed infrastructure.
Swapping makes a ton more sense than sitting 20-60 minutes for a full charge.
- Faster turnover. (Can get 6-15 more cars in in an hour, equivalent to gas queues) - Guaranteed full charge. - No/ smaller queues, so less infrastructure needed (waiting for available spots, etc.)
CATL claims that the first standardized batteries for commercial electric vehicles like heavy-duty trucks will save their owners $8,000 per 60,000 miles compared to gas trucks. CATL is now spearheading the battery swap concept and building stations for both passenger EVs and heavy-duty trucks.
