Frequently Asked Questions

How to select SiC modules for different power level charging stations?

Power level and module selection: (1) 30-60kW: BM300F12B34U2. (2) 60-120kW: BM600F12B34U2. (3) 120-180kW: BM840F12B34U2. (4) 180-350kW: BM950F12B34U2. Multi-module paralleling is also possible, such as 2x BM600 for 240kW.

Contact FAE for optimal selection based on target power level and cost budget.

What are the advantages of SiC charging stations compared to IGBT?

SiC charging station advantages: (1) Higher efficiency: 99% vs 97%, saving approximately $5000/year in electricity for a single 120kW charger. (2) 3x higher power density, saving footprint. (3) Supports higher switching frequency, reducing magnetic component size. (4) Lower cooling requirements. (5) Lower cooling costs.

Calculate TCO (Total Cost of Ownership). SiC solutions typically recover the cost premium within 2-3 years.

How to design thermal management for charging stations?

Thermal management solutions: (1) 30-60kW: Forced air cooling, heatsink thermal resistance <0.15K/W. (2) 60-120kW: Enhanced air cooling or liquid cooling. (3) 120kW+: Liquid cooling recommended, heatsink thermal resistance <0.08K/W. SiC has lower losses, cooling requirements are 30-40% lower than IGBT.

Provide power level and environmental conditions, FAE can perform thermal simulation and heatsink design.

Is V2G (Vehicle-to-Grid) functionality supported?

Yes, SiC module-based topology supports bidirectional power flow for V2G functionality. Requires bidirectional control algorithms and grid interface design. We provide bidirectional charging station reference designs supporting grid-connected and off-grid modes.

V2G applications require additional grid certification. Contact FAE for detailed design solutions.

What are the EMC design considerations for charging stations?

EMC design points: (1) SiC's high dv/dt requires special attention to EMI suppression. (2) Use shielded gate drive and common-mode filtering. (3) Proper PCB layout and grounding design. (4) Input/output filter design. We provide EMC optimization guidance and pre-testing support.

EMC issues can be prevented at the design stage. Early design review with FAE is recommended.

Do you provide complete charging station solutions?

We provide power module-level solutions including: (1) Power modules and drivers. (2) Power unit reference designs (30kW modules). (3) Control algorithms and communication protocol stacks. (4) Complete system integration guidance. Customers can quickly develop their own brand charging stations based on this.
