Changing Lanes to 800V EV Power Systems
Though most EVs today use 400V architecture, 800V may become the standard in the future.
EV vehicles were 3.2% of total vehicles sold in 2021, but will be 32% of total vehicles sold by 2030*
Total charging time reduced by 80% between 400V and 800V systems**
Global sales of EVs are estimated to grow to 30+ million vehicles by 2030*
Faster charging time
Less heat generation
Thinner cables
Smaller motors
Power Distribution Unit
Power Distribution Unit
The high voltage power distribution unit (PDU) is a central element of the electrical architecture in an electric vehicle. It establishes the electrical connection between the battery, on-board charger, motor and other consumers such as heaters, DC-DC converters, etc.
Charging systems
Charging systems
Faster charging is enabled with an 800-volt system because lower current reduces overheating in the charging cables and associated hardware. Higher voltage systems also charge differently than lower voltage systems and can provide faster charging.

Battery management & monitoring
800V architectures can support smaller batteries and battery management systems (BMS). A smaller battery and BMS translates to lower weight, higher ranges and better overall performance. The higher voltage generates lower current which in turn reduces heat output.

Smaller motors
Using higher-voltage systems can lead to the amount of copper used in motors being significantly cut, creating smaller, lighter, and more environmentally friendly motors.
Accessories & thinner cables

More space, more efficiency
More space, more efficiency
Lower current also means charging cables can be thinner and less cumbersome, and certain electrical components in the car can also be thinner and smaller, making the car more lightweight and efficient.
