The DC Fast Charging Interface
DC charging made easy
To maximize the flexibility of battery-electric commercial vehicles such as construction machinery and other off-highway vehicles, they must be able to charge quickly. This minimizes downtime. The INTERFLOW or MEGAFLOW DC fast-charging interfaces are the perfect solution for this. They enable the integration of an MCS, CCS, or GB/T interface into the vehicle or machine's HV side, handle communication with the charger, monitor the charging process, and guarantee safety. Compared to alternating current (AC) charging using, for example, construction site power and internally installed chargers, direct current (DC) charging with an external charger allows for significantly higher performance and therefore shorter charging times. The DC fast-charging interfaces were developed for tough everyday use and feature a robust aluminum housing, stable all-metal cable glands, and high-quality internal components. Each product is carefully manufactured in-house at SUNCAR and undergoes a thorough testing process to guarantee reliable and safe operation. The optional external charging controller enables charging according to the latest industry standards, enables customer-specific configurations, and communicates with both the charging station and the vehicle control system via the CAN bus.
Configurations
The DC fast charging interfaces are available in different power levels for various vehicle or machine sizes, each with a voltage of up to 1000 V. If an additional high-voltage distribution system such as our FUSION is required, the INTERFUSION800M can be used as a combined fast charging and distribution module.
Safety
The charging process is continuously monitored by precise, galvanically isolated current and voltage meters, as well as temperature sensors on the charging socket and in the housing, which throttle the charging power if the temperature limit is exceeded. Furthermore, the INTERFLOW and MEGAFLOW are integrated into the machine-wide interlock system via the interlock switch. If a component of the high-voltage system is opened, the interlock system is triggered and activates the battery contactors, which disconnect the machine from the power source. The housing can be earthed at the earthing stud and is also connected to the conductive cable sheath of the input and output cables via the EMC cable glands in order to intercept and earth electromagnetic interference.
