Robert Fisher of SBD Automotive Discusses the Shift to 800-Volt Architectures in EVs and Challenges with Backward Compatibility and Supply Chain Limitations

Robert Fisher from SBD Automotive, a global consulting firm specializing in emerging automotive technologies, presented on 800-volt architectures and their significance for the industry. Most current electric vehicle (EV) systems run on 400 volts; however, the shift to 800 volts brings notable advantages. The power law indicates that doubling voltage cuts current in half while drastically reducing wasted heat per Ohm’s law. This reduction translates into smaller, lighter motors with fewer cooling requirements and faster charging times due to less heat generation during charging. Despite these benefits, several challenges impede widespread adoption of 800-volt systems: existing supply chains are geared towards 400-volt components; backward compatibility issues require additional equipment for mixed-voltage scenarios; and regional discrepancies further complicate transitions—Europe is advancing rapidly toward higher voltages while other regions lag behind or use different standards like China’s prevalent 750 volts. Solutions exist but involve complexities such as battery reconfiguration devices to allow dual-voltage integration or DC-DC converters for voltage conversion.
