The EV gets to just run everything backwards when you step on the brakes. This won't stop you, but it'll make a huge difference to the remaining force needed to stop you, so it massively reduces wear on brakes and (which is why they did it) increases the effective range of the vehicle. And since they aren't worn out, the brakes need maintenance far less often. Driven gently the brakes on a EV might last its useful lifetime.
You can't do this with ICE, if you put diesel fumes in a compression chamber and pump the cylinders up and down, it doesn't turn back into diesel fuel, combustion isn't symmetric, so you need to actually have brakes.
Electric vehicles and hybrids use regenerative braking from the motor for a lot of their stopping power. They do still need brake work but significantly less often (100-200K mile interval vs ~50K though there is considerable variance depending on driving habits) because the friction brakes are engaged less often and so wear down more slowly.
Electric braking, useful 90% of the time to slow down. Hydraulic brakes only get used for a full stop. It's like engine braking on steroids and fully integrated into your brake pedal so that you don't need to know which brake system operates at a given time.
I doubt it's due to the EV's regenerative braking; if anything, that's a more complex system with more things that can go wrong.
The answer is probably easier: a Prius is 3300 lbs and a Dodge Ram is 6600 lbs and carries much, much more if working. Those truck brakes are going to be thrashed much harder.
The regenerative braking system is not complicated at all. In fact, it comes basically for free!
All that happens is you cut power to the motor but leave the wheels attached to the motor. This is the same as "engine braking" on a manual. The wheels turn the motor, which steals kinetic energy from the car and charges the battery.
There's no extra bits or anything. It's all in the drivetrain that's there already.
Did you not pay attention in high school? When you step on the gas your car, you are converting electrical energy into kinetic energy. When you release your foot, the kinetic energy that is stored into the car moves tires, which moves the shaft of the electric motor. What happens if you manually rotate a conductor inside a magnetic field? Obviously induction happens, which converts the kinetic energy back into electricity and heat.
>more things that can go wrong.
Eddy Current Brakes are a passive system with an extremely high safety track record. If you ignore the bearing that holds the wheel/motor in place there are no moving mechanical parts. I couldn't think of a safer way to stop moving objects.
It's not complex at all and it's a consequence of electric motor operation. The engine goes into generator mode if you turn the supply into a load, which is very easily done and can also be easily done gradually. Regenerative braking uses this generated power to recharge the batteries, but you can essentialy do anything with it, the easiest thing being converting it into heat using a resistor.
