1. Major EVCC Manufacturers in China
VMAX
VMAX has EVCC as one of its core products.
Its EVCC products are deeply integrated into onboard power systems and support protocol conversion from Chinese GB/T standards to European, North American, and Japanese standards.
They can be adapted to mainstream vehicle brands and have already been applied in exported vehicle models.
Technical highlights include multi-protocol compatibility, such as ISO 15118 and CHAdeMO, as well as OTA upgrade support and security encryption mechanisms.
Share Charging ECO-EVCC
Share Charging provides full-stack electric control solutions.
Its EVCC products cover both passenger vehicle and commercial vehicle applications, supporting cross-domain integration between power domains and charging communication protocols.
Application scenarios include logistics vehicles, autonomous buses, and other special vehicle platforms.
The solution supports remote diagnostics and customized protocol development.
In integrated electric drive systems, the EVCC module can help achieve global charging protocol adaptation, including European CCS and North American SAE standards.
An important innovation direction is the integration of EVCC with thermal management and low-voltage BMS functions, helping improve overall system energy efficiency.
2. Leading International Manufacturers
Western Automation
Western Automation has launched standardized EVCC-01 controllers.
These products comply with international safety standards such as IEC 61851 and support UART communication interfaces, as well as 16A and 32A current configurations.
Typical application scenarios include public charging equipment and home charging equipment.
Bosch
As a leading company in electric control systems, Bosch integrates EVCC solutions into domain controllers.
Its solutions support V2G, or Vehicle-to-Grid interaction, as well as PnC, or Plug and Charge.
One of its advantages is support for TLS encrypted authentication based on ISO 15118, covering high-end passenger vehicle applications.
ZF
ZF develops EVCC technology in coordination with electric drive systems.
Its focus is on high-power fast charging protocol conversion and supporting high-end vehicle models from European and North American vehicle manufacturers.
3. Technical Cooperation Ecosystem
Vehicle Manufacturer Cooperation
Vehicle manufacturers such as BYD and Geely reduce export adaptation costs through self-developed EVCC modules.
Chip Support
Suppliers such as DENSO provide underlying communication chips to improve protocol conversion efficiency.
Note
The EVCC market is currently driven by professional suppliers such as VMAX and Western Automation.
At the same time, vehicle manufacturers such as Geely and Tier 1 suppliers such as Bosch and ZF are accelerating integrated EVCC development.
This trend is helping promote global charging compatibility for electric vehicles.
