Whether electric vehicles sell well or not depends largely on the charging experience. When it comes to how to quickly “recharge” a vehicle, two camps have long existed in the industry: one is focused on maximizing ultra-fast charging power, while the other insists on replacing the entire battery pack.
I. The "Super-Charging" Camp: Crank Up the Power
With an 800-volt platform combined with liquid-cooled ultra-fast charging stations, peak power has surged from over 200 kilowatts all the way to 480 kilowatts, and the heavy-duty truck sector is even talking about megawatt-level charging. Combined with batteries capable of 5C and 10C charge rates, a charge from 20% to 80% can be achieved in just over ten minutes. The trade-off is that the batteries must be durable enough to withstand this, and the power grid must be able to supply the necessary power.
II. The Battery Swapping Camp: Simply Swap in a New Battery
The concept behind battery swapping is straightforward: when the battery runs out, pull into a station, swap it for a fully charged battery pack in a few minutes, and be on your way—the experience is almost identical to refueling a car. It’s particularly beneficial for commercial vehicles; ride-hailing cars and taxis operate for over a dozen hours a day, so the time saved on charging translates directly into money. The problem is that battery pack specifications vary widely, making standardization difficult, and battery-swapping stations themselves are capital-intensive investments.
| Dimension | Supercharging | Battery Swapping |
|---|---|---|
| Recharge Time | 10–15 minutes (20%–80%) | 3–5 minutes |
| Asset Model | Piles, which are relatively light | Station + Backup Power, Heavy |
| Standardization | The charging ports have been standardized | Challenges in Standardizing Battery Packs |
| Best Suited For | Private Car | High-Frequency Service Vehicles |
III. Do We Really Have to Choose Between the Two?
A more likely outcome is a coexistence of different approaches: private cars will primarily use ultra-fast charging, which handles the vast majority of scenarios; high-frequency commercial vehicles, such as taxis and ride-hailing cars, will rely on battery swapping to minimize downtime. For battery swapping to truly take off, the industry must first establish a unified standard for battery packs.
In the next phase of the new energy vehicle industry, charging is no longer driven by a single technological breakthrough, but rather by the combined progress of infrastructure networks, standards, and user habits.
