Hi guys, I know that you can get horsepower by knowing the watts of a eletric car/engine but which kW do I use in this situation?

When you see a vehicle’s power being advertised, it’s always the maximum amount of power that the motor can produce.
Let’s look at the 3.5L V6 PowerBoost hybrid engine in the 2021-2022 model Ford F-150. It’s advertised as having 430hp but only gets that from around 4500-5500rpm and only with a certain octane of gas.
In this case, the electric motor would be advertised as 180kW / 240hp.
The actual power at any time depends on a number of factors, including the input power level (fuel octane/battery voltage) and RPM. For an electric engine, heat from continuous running can also reduce power output, as seen from the 30min values in the chart.
I actually doubt that most ice cars can reject heat produced at peak power output indefinitely, I just never saw that listed as a continuous power output. But yeah, peak numbers are what matter for everything but extreme use cases.
