So, CHAdeMO and CCS2 are not directly compatible due to differences in regional usage, connector design, and market adoption. Therefore, using a specialized CHAdeMO to CCS2 adapter is necessary to enable safe and efficient DC fast charging across these standards.
How a CHAdeMO to CCS2 Adapter Works
Basic Function
A CHAdeMO to CCS2 adapter acts as a bridge between the charging station and the electric vehicle. It “translates” the signals and electrical connections from a CHAdeMO DC fast charger to be compatible with a CCS2-equipped EV. This ensures that the charging session can start, maintain stable power delivery, and stop safely without any interruptions or errors.
High Voltage and Current Support
Because DC fast charging involves high voltage and large currents, the adapter must be capable of handling these safely. Typical requirements include support for several hundred volts of DC and high amperage, ensuring the EV receives fast, efficient, and reliable charging while maintaining safety standards.
Manufacturer Example
From a manufacturer’s perspective, products like the OLINK CHAdeMO to CCS2 Adapter are designed to meet these demanding conditions. Many of these adapters support up to 1000V DC and 250A, making them suitable for common DC fast-charging scenarios. With proper insulation, temperature control, and robust connector design, such adapters provide both reliability and convenience for users and charging station operators.
