Does a battery deliver the same at 10% vs 90%?

213 views

An EV for example: if the car has 10% charge left, does the battery have less power or amps or whatever than it does when it’s at 90%? Or an iPhone at 20% vs 80%…same question. Or, from the battery’s perspective, even to 1% left, it’s either on or off, regardless of charge remaining?

No it doesn’t, but depending on the application it might not matter. A electric car might have slightly lower acceleration on low charge, but unless you are on a racetrack you are unlikely to accelerate at max speed anyway.
