2.2MW Single-Gun Charging Released: Importers Should First Verify Charging Protocol

The real value of a single-gun 2.2MW charger is not how fast it charges, but whether imported cars can plug into such liquid-cooled megawatt chargers. The power limit of the charger is no longer the bottleneck; the battery's acceptance power is: selling a car that only supports 400V, 120kW to a market full of megawatt guns means customers pay but don't get the speed they expect, and this account will ultimately be charged to the importer. To judge the value of megawatt-level single-gun charging, the order is to first look at how much the vehicle can take, then how much the charger can deliver; reversing the judgment will inevitably lead to problems with orders. This kind of judgment doesn't need to wait for the press conference to end; it can be done with a model parameter sheet at almost zero cost, but the cost of missing it once could be the entire batch of cars stuck in hand. For procurement, this kind of release is not a selling point news, but an opportunity to align the models on sale with the target market's charger fleet.

Geely released AI Smart Charging (AI Zhichong) in September 2026, with single-gun peak power increased from the previous generation's 1.5MW to 2.2MW. The official positioning is full ecosystem collaboration of 800V vehicles, chargers, and grid, according to Sina Auto. The same set of numbers means different things to different roles: charger companies see turnover rate, OEMs see platform capability, and importers should see entry barriers. It describes the upper limit of the charger's capability, not the upper limit of the car you have. Operators are willing to push single-gun power to megawatt level because they want the same parking spaces to serve more vehicles per day, which is independent of how much power your supplied cars can accept. In other words, the stronger the charger, the more it tests the importer's judgment when selecting cars, and the more it amplifies the cost of choosing wrong.

Let's do the math. Take a 100kWh battery, charging from 10% to 80% adds about 70kWh: the theoretical time for 1.5MW is 2.8 minutes, for 2.2MW is 1.9 minutes, a difference of less than 1 minute. But the peak acceptance power of most 800V production cars falls between 250–400kW. For 70kWh at 350kW, theoretically it takes 12 minutes, but in practice, limited by cell C-rate and thermal management, the common range is 18–25 minutes. That is, increasing the gun from 1.5MW to 2.2MW hardly changes the charging time for real vehicles; what really determines the time is the vehicle's acceptance power and thermal control strategy. This conclusion can be directly relayed to customers: the charger's power limit is no longer the bottleneck. Putting this sentence into the technical explanation for customers is more persuasive than listing rated power.

For importers, what really needs to be verified are two things: the charging protocol of the export model, and its maximum acceptance power. The protocol determines whether it can be plugged in—China uses GB/T, Europe mainly CCS2, Japan CHAdeMO, with different pin shapes and communication handshakes. If the interface doesn't match, no matter how high the charger power is, it's just an unusable gun; power determines how much can be drawn after plugging in. If the target market only has liquid-cooled megawatt guns, and you supply a 400V, 120kW model, the charging time on the promotional page can only be delivered at 120kW, and after-sales complaints will ultimately be charged to your account. Writing these two items as hard indicators on the quotation is much more useful than marking peak power on the promotional page.

First, request three documents from the supplier: vehicle charging protocol and interface standard description, actual measured charging curve from 10% to 80%, and battery thermal management specification, and include them in the technical package for customers. The second step is to compile a table of mainstream charger power levels in the target market, and match them item by item against the vehicle's maximum acceptance power; for models that don't match, don't rush to place orders—changing models is usually cheaper than changing markets. To confirm the charging compatibility and landed cost of a specific model in the actual market, you can provide the model and configuration list to get a quote; this step takes half a day, but may save the rework cost of an entire batch of cars.
