For light electric vehicles, the loading is best described as pulsed with high duty cycle.
It's certainly not constant power, so the constant current mode would apply.
But I need some help choosing the most suitable load select value.
Acceleration loads peak at 1C dropping to 0.5C-0.7C.
What Load Select Value is recommended?
Thank you.
Hello Rom,
I would leave the load select until you have tested it with your system, then modify it if needed. The default is fine for most applications. between 1C to 0.5C is not extremely dynamic.

Hello Wyatt,
The dynamic range given is for acceleration to cruise. Of course it drops to nearly zero when the vehicle stops or parked.
Does this make a difference?

Hello Rom,
If you want the most conservative estimation, you can use the User Rate option and set it to the average maximum current used by your application. This will ensure the gauge always uses a higher current value so you would most likely hit 0% early, but you wouldn't have any jumps to 0% if the load is pulsed high.

Hello Wyatt,
I'm about to start the learning cycle.
Am I to use the default for learning, and then change to the User Rate option afterwards?

Hello Rom,
The load select will have no impact on the learning. You should change it after learning is completed and you are configuring your device to export the golden image.
