Therefore, we say that there are currently five major charging standards worldwide. The five major standard interfaces are the Chinese standard based on GB/T 20234, the North American standard CCS1 based on J1772, the European standard CCS2 based on IEC 62196, the Japanese standard based on CHAdeMO, and the Tesla standard based on NACS.
Standardized charging protocols are crucial for efficient and safe communication in the EV charging ecosystem. They help CPOs, EMSP, EV regulators, and EV drivers simplify access control and load management processes. We can identify various participants in the EV charging system who communicate with each other based on protocols.
Tesla Charging Standards The common charging standard in the United States is J1772, with the only exception being Tesla, which has developed a dedicated charging interface for Tesla electric vehicles. Tesla announced its NACS standard on November 11, 2022.
Chinese Charging Standards The reference standards for the charging interface and handshake circuit of electric vehicles in China are GB/T 20234 and GB/T 18487.1 respectively.
Combined Charging System (CCS) stands as a foundational standard for charging electric vehicles, including AC and DC charging, communication between EV charging stations and cars, load balancing, authentication, authorization to charge, and vehicle couplers (connectors at the end of charging cables and corresponding inlets in vehicles).
There are two versions of the CHAdeMO standard. The first version supports charging up to 62.5 kW and a maximum charging current of 125 A; while the revised CHAdeMO 2.0 specification allows up to 400 kW. Figure 9.

Online Services Email ContactPhotocells Photocell lights are a great solution. Photocell detectors are sensitive to changes in lighting levels and can switch lights on or off as needed. When light decreases at dusk, photocell lights will switch on, turning off when light increases again at dawn. Photocell lights are convenient, energy-efficient and environmentally friendly.
Online Services Email ContactThe working principle behind photocell outdoor lights is quite simple. The photocell sensor, located on the top of the light fixture, detects the amount of daylight present. When the daylight levels drop below a specific threshold, the sensor triggers the light to switch on. This threshold can usually be adjusted to suit the user''s preferences.
