High-power charging
DC charging at 150 kW and above, up to about 400 kW for cars, usually at 800–1000 V so the current stays within what cable and connector can carry. Liquid-cooled cables make the currents of 500 A and more practical.
- Abbreviation
- HPC
- Also called
- ultra-fast charging, ultra-rapid charging
Example
Charging infrastructure: an example situation
A 100 kW model request does not establish real voltage, current, connector or negotiation compatibility.
Read High-power charging alongside Charging curve in this context. The power a vehicle actually accepts against its state of charge during a fast charge: high at low SOC, stepping down as the cells approach voltage and plating limits. The area under it, not the peak kilowatts, decides how long a stop takes.

This overview identifies the components to use. Follow the example in Lemonergy for their connections and settings.
- Select a rechargeable cell and pack.
- Open Analysis → Charge session; increase power.
Example. A 50 kW source at 400 V cannot deliver 50 kW through a 100 A ceiling; that current limit corresponds to 40 kW.
Observe. Read the named limiting reason.
This differs from the Studio network and requires cell resistance data and product access.
