Do All EVS Have Regenerative Braking?

The concept behind regenerative braking came around well over 20 years ago. This was after the first Toyota Prius was rolled off the line.

From that time till now, the concept of regenerative braking has gained popularity but not entirely embraced by all hybrid electrical vehicles.

No, not all Electric Vehicles (EVs) have regenerative braking. Regenerative power recovery refers to regenerative braking, where an EV’s heat energy produced during braking is converted to electrical energy.

This is a fairly well-known method of increasing the range of hybrid and other electric vehicles.

However, did you know that regenerative braking is not only limited to electric vehicles?

Indeed, you will find that this concept is being used in many platforms, including electric bicycles and electric skateboards to electric scooters.

As insinuated earlier, moving vehicles possess much kinetic energy. On applying brakes to slow down the vehicle, such kinetic energy (all of it) needs to go somewhere.

Unlike in the ancient past, when all brakes depended on friction, the vehicle’s kinetic energy ended up as wasted heat to decelerate a car.

All of that energy was lost to the environment. Thanks to regenerative braking, such energy can be harnessed and brought back to use.

This is a technology that needs to be incorporated into all EVs. Such measures would mean that the environment is conserved better and carbon footprint decreased.

But I need to mention that regenerative braking is far from being a magical range booster for your EV.

Technically, it won’t make electric vehicles more efficient; it just makes them less inefficient.

What Is Regenerative Power Recovery Ninebot?

Regenerative power recovery Ninebot is the use of regenerative braking and downhill assistance control.

As you ride your Ninebot scooter downhill, the system will automatically control and manage the speed as it collects its kinetic energy, storing it in the battery to be used later.

It collects the energy generated by the scooter during a ride and recycles the same energy into battery power for use by the scooter later.

This technique minimizes the energy input to an overall system by exchanging energy from one sub-system to the battery.

When Ninebot benefits from regenerative power recovery, there is a visible increase in the battery indicator.

Indeed, so effective is the system that it can even overcharge the battery, so you need to be careful not to exceed 100%. 

But Ninebot is not the only device using this form of technology. Indeed, most modern electric rideables use regenerative braking to enhance the range of their products.

This means that anytime the device goes faster than intended, the motors turn into generators.

And because generators require energy to operate, this will slow down the device.

In the process, there is energy production that is then directed back into the batteries.

In essence, this means the energy used climbing the hill is somehow recovered, hence regenerative recovery.

What Does Energy Recovery Do On Ninebot?

Energy recovery gives more juice to your battery. The favorite term is recovery, but I think energy generation is more precise.

This is because, in recovery, you can only recover as much as you lost but not anything more than that. This is not the case with Ninebot energy recovery.

Indeed, you get as much energy as your hill will allow. You may get less than what you had in the battery or get more than what was available in the battery before the decline.

The first important thing to note here is that an electric generator and an electric motor are the same things.

The name you call this device at your moment depends on the direction of the flow of electricity. This will be either from or to the battery.

In the case of a generator, the circuit will have to be complete (your wheel will have to be turned on) as you go downhill or as you brake.

In either situation, the energy flow is reversed, making it flow back to the battery.

But if your wheel is turned off, the motors will offer little resistance to turning the wheel.

Unlike when it is on when the generator (not a motor anymore in the circumstances) offers great mechanical resistance to turning.

What Is Regenerative Braking In A Scooter?

Regenerative braking in a scooter activates regenerative brakes by switching to electrically couple the electric motor into the charging system.

In the process, resistance to motor rotation is created. The general idea in this system is to recover energy during braking and consequently extend the scooter’s range.

On a sizeable number of models of scooters, the regenerative braking is activated as soon as the throttle is released.

Does Ninebot Max Come Charged?

However, on others (the majority), regenerative braking is activated by either a dedicated button or the brake lever.

It’s essential to note that no single electric scooter will only come with regenerative braking since it’s far from an effective enough system standalone.

Indeed, regenerative braking works in theory; but it’s far from getting anywhere near mechanical brakes.

The best part of this type of braking is that it will significantly improve the range of any scooter when used effectively, depending on the riding techniques and riding terrains.

Unfortunately, most scooter companies will never tell you how much energy will be recovered in reality when using this system.  

In most instances, most scooter companies greatly overstate how much extra juice goes back to the battery courtesy of electric scooter brakes.

Most people do not consider regenerative braking a viable option for extending an electric scooter’s range.

The advantages of regenerative brakes include lack of additional weight and maintenance and significant energy recovery.

However, the system is not without disadvantages. First, such braking is not effective and is largely poor;

It will scarcely work if the battery is fully charged, and some regenerative braking systems are poorly implemented.

How Does Regenerative Braking Work On A Scooter?

The activation of regenerative brakes on your electric scooter incorporates the DC motor into a power generation circuit used as a charging circuit to charge your battery.

Bearing in mind you’re your electric scooter has a charging circuit meant to charge the battery, what is done with regenerative braking is to enlist them on the charging circuit.

Consequently, electrons are forced back into your scooter’s battery. And this creates a drag on the motor.

While belittled by some schools of thought, this value is reliable brakes and energy savings, resulting in an extended range.

However, as I mentioned, some schools of thought feel that the whole idea is overhyped.

Such argue that first, there is not much kinetic energy to capture, and secondly, batteries won’t be recharged very fast.

They also argue that these cannot be good brakes to depend on since they are only effective when going fast enough.

Well. These seem like valid arguments. But the truth is that this is a repeated process as you continue with your ride.

Since your scooter’s battery is not being recharged from flat, it will benefit from the repeated regenerative energy recovery, resulting in an actual extended range.

As to how regenerative brakes work, there is a point that they are weak. When using them, it’s not easy to stop quickly.

Additionally, they are inadequate in emergencies as the braking strength is from a counter electromotive force (CEMF) opposing the rotation of the motor.

The braking is strong initially, but it fades quickly since the motor’s forward rotation creates CEMF.

Do Regenerative Brakes Last Longer?

Yes, regenerative rakes last longer.

While ordinary brakes pads last between 30,000 and 60,000 miles, you can get anywhere between 70,000 and 100,000 miles from your regenerative brake pads.

When you hit your brakes on an EV, that energy is committed to charging your battery first. It will only wear on the brake pads at the tail end of your braking process.

The only other time it will wear down on the brake pads is when the brakes are applied instantly or rapidly.

A brake pad’s lifespan is affected by several factors. Some of these factors are within your control, while others are beyond your control.

These include driving environment, driving habits, driving peed, braking speed, cruising, and following distance.

Does Regenerative Braking Turn On The Brake?

Yes, usually, but not always the case. While your brake lights will come on when regenerative braking occurs, you should be aware of some exceptions to this rule.

You need to consider things before riding, believing everyone can see your braking when regenerative braking is in effect.

First, you need to understand that two types of regenerative braking happen to be different from each other.

When it comes down to how they operate, the operation is slightly different from either system. Consequently, your brake lights will be affected differently.

One way of using regenerative braking is pressing the brake pedal. If you do, your brake lights will come on, provided all your brake lights are in a functional state.

This means that any vehicle behind you will know that your speed is decreasing, and this will allow them time to adjust their speed accordingly.

In this instance, your electric motor will enter the generator mode, collecting energy from the heat and converting it to additional power stored in your EV’s battery.

Consequently, you will access more power and a better range.

On the other hand, the second type of regenerative braking kicks off when you release the throttle or remove your foot from the pedal.

Making the regenerative braking system kick in automatically. In reality, it will do the same task of gathering all kinetic and heat energy from your braking and transferring it to the battery.

In this second type, it’s unpredictable as to whether regenerative braking will turn on the brake lights or not.

Therefore, it’s advisable to use the brake pedal when using regenerative braking to ensure that other road users know you are slowing down.

What Is Regenerative Braking In DC Motors?

This is an energy recovery device for slowing down a moving car or an object by converting its energy from kinetic to another form of usable energy.

This energy is stored in a battery and will be used only when required from the battery.

A regenerative braking system compares with an ordinary braking system, where the surplus kinetic energy is changed into heat because of friction within the braking system.

The regenerative system uses the motors to drive an electric vehicle and the braking function in DC motors.

The DC motor performs dual functions including, stepping in as a generator and as an ordinary motor.

This means that the motor will work in both directions where, in one direction, it will work as a generator and in the other direction work as a motor.

As soon as the brakes are applied, the DC motor will run opposite to an electric generator, slowing down the wheels.

And it’s the wheels that will produce the kinetic energy that the generator will change into electrical energy while rotating.

Consequently, it will transmit such generated electricity to charge the batteries.

Energy Recovery, How Does It Work? Which Maneuvers?

In all battery-powered electric vehicles, regen (regenerative braking) converts the vehicle’s kinetic energy into another form of energy (chemical) stored in the battery.

This stored chemical energy can later be used to drive the vehicle. Since this system is also used to slow the vehicle down to a stop, it qualifies for the name “regenerative braking.”

The term regenerative is chosen since it works in recapturing the energy into the battery where it can be re-used.

Ideally, the moving vehicle’s kinetic energy relates to the vehicle’s mass and speed by the equation E = ½mv².

Consequently, if all else is equal, and your car is twice as heavy, it has double the kinetic energy and moves twice as fast, resulting in four times the kinetic energy.

And if your vehicle slows down, there has to be a place for the kinetic energy stored in the vehicle to go.

As you know, there will always be some kinetic energy consumed by the resultant rolling resistance, aerodynamics of the vehicle, and mechanical friction.

All these forms of energy are wasted in heating the road, various spinning parts of the EV, and the surrounding air.

However, the vast majority of this energy is converted into heat through braking.

Fortunately, regenerative braking is designed to recover this energy and get it to the battery as electrical energy that will later be used to improve your EV’s range.

Conclusion

Regenerative power recovery refers to regenerative braking, where an EV’s heat energy produced during braking is converted to electrical energy.
