As we all aware that the biggest obstacle of applying EV for utility is the long charging time, unlike the private vehicle , utility vehicle need to run all the time to maximise ROI. Hours of charging and queue up for charging is not the right model for the business. Imagine the utility vehicle can recharge in full in just 3 mins! It change the whole ecosystem and make the whole "no pollution" initiative become profitable and might even better than traditional gas station approach.
Battery swapping makes it possible for people to buy new electric vehicles without the battery, whose cost will be lower than a combustion engine-based vehicle. Battery swapping should be a public network asset, and we are investing in that network.
