Question 1

What charging standard does China use for EVs?

Accepted Answer

China uses GB/T 20234, a mandatory national standard governing both AC and DC EV charging. It requires separate connectors for AC slow charging and DC fast charging, managed under different parts of the standard (GB/T 20234.2 for AC connectors, GB/T 20234.3 for DC connectors).

Question 2

Is GB/T the same as CCS?

Accepted Answer

No. GB/T and CCS are incompatible standards without adapters. GB/T uses separate AC and DC connectors specific to the Chinese market. CCS (Combined Charging System) uses a single combined inlet for AC and DC and is dominant in Europe (CCS2) and North America (CCS1). The two systems cannot be used interchangeably without a certified adapter.

Question 3

Can I use a GB/T charger outside China?

Accepted Answer

GB/T chargers are compatible with Chinese-market EVs fitted with GB/T inlets. In most international markets, EV fleets use CCS2, CCS1, or NACS. A GB/T charger would only serve vehicles with a matching GB/T inlet — which outside China is typically limited to Chinese-market vehicles that have not been converted for export.

Question 4

Will ChaoJi replace GB/T?

Accepted Answer

ChaoJi is the next-generation evolution of GB/T, not an immediate replacement. It is backward compatible with existing GB/T DC infrastructure via adapter. Adoption will accelerate as ultra-high-power vehicles (above 350 kW charging capability) enter the Chinese market. Existing GB/T DC hardware is not made obsolete by ChaoJi.

Question 5

Do exported Chinese EVs still use GB/T?

Accepted Answer

No. Chinese EV manufacturers adapt their vehicles for export markets. EVs exported to Europe receive CCS2 inlets; those exported to North America receive CCS1 or NACS. GB/T connectors are retained only in the Chinese domestic market specification.

Question 6

How much power does GB/T DC charging support?

Accepted Answer

Current mainstream GB/T DC public infrastructure supports up to 237.5 kW (1,000V x 250A). The 2023 revision of GB/T 20234.3 enables up to 1,200 kW (1,500V x 800A) for ChaoJi-capable hardware and vehicles. BYD’s Flash Charging system, launched in March 2026, delivers up to 1,500 kW through a proprietary high-power implementation.
