can evs charge on the road while driving
12May, 23 May 12, 2023

At the moment, electric vehicles (EVs) require a stop at a charging station to refuel their batteries. Depending on the battery’s capacity and the charger’s speed, this process could take anywhere from 30 minutes to several hours. On the other hand, there has been an increase in interest in creating technology that enables EVs to charge while traveling on public roads. By doing so, frequent pauses at charging stations would be unnecessary, and it might even extend EVs’ range. I’ll discuss the condition of this technology right now and any potential ramifications in my response.

Can EVs Charge While Driving on the Road?

Yes, it is technically possible for electric vehicles (EVs) to charge while on the road. This is made possible by “dynamic wireless charging” or “inductive charging” technology. It functions by employing magnetic fields to transfer energy from a charging pad located on the road to a receiver on the undercarriage of the electric vehicle (EV), which then transforms the energy into electricity to charge the battery. But this technology is still in its infancy and hasn’t been extensively used yet. Before dynamic wireless charging can be used to charge EVs on the go, there are still a few technological and logistical issues to be solved.

When braking, can an electric vehicle charge?

Yes, using a technique known as regenerative braking, an electric vehicle (EV) may transform part of the kinetic energy into electrical energy as it brakes and store it in the battery. To do this, the electric vehicle’s motor is used as a generator to slow down the car and turn the energy it produces into electrical energy, which is then pumped back into the battery. EVs’ ranges can be increased, and brake wear and tear decreased with regenerative braking. However, the quantity of energy that may be recovered through regenerative braking varies on a number of variables, including the vehicle’s speed, the EV’s weight, and the intensity of the regenerative braking used.

Technologies for Charging EVs While Driving

There are several technologies currently being developed for charging electric vehicles (EVs) while driving on the road:

Dynamic wireless charging:

With the use of a technique called dynamic wireless charging, commonly referred to as inductive charging, electric vehicles (EVs) can charge wirelessly while driving. A receiver coil is positioned on the undercarriage of the EV, and a charging pad or coil is implanted in the road. The battery is charged by the charging pad’s magnetic field, which causes a current to flow through the receiver coil, which subsequently turns the energy into electricity. Dynamic wireless charging may make EVs more suitable for long-distance travel by reducing the need for refueling pit breaks and extending the range of EVs. Nevertheless, because the technology is still in its infancy, there are still a number of technical and logistical issues that must be resolved, including maintaining the security of the charging system and creating charging standards that are appropriate for various EV models.

Conductive charging:

Electric vehicles (EVs) can charge while on the road thanks to a technology known as conductive charging that creates a conductive connection between the car and a charging plate buried in the pavement. In order to transfer electrical energy to charge the battery, the conductive charging system normally consists of an arm or connector located on the undercarriage of the electric vehicle (EV) that interacts with a conductive plate on the road. Because it can deliver a high-power charging rate, conductive charging has the potential to offer an EV charging solution that is more effective, particularly for heavy-duty or high-power applications. However, there are several drawbacks to this technique, such as the requirement for direct physical contact between the vehicle and the charging plate, which could be dangerous, and the possibility of charging plate deterioration with time.

Overhead electrification:

With the use of overhead power lines or catenary wires that supply the vehicle with power, overhead electrification is a technique that enables electric cars (EVs) to charge while traveling on public roads. The method uses a pantograph or other current collecting device to deliver electricity from overhead lines or wires to the vehicle, much as how trains and trams are powered. As overhead electrification may offer a high-power charging rate, it has the potential to offer a dependable and effective charging option for heavy-duty EVs like buses and trucks. But because it can be challenging to execute in urban settings with overhead impediments, such bridges and tunnels, this technology necessitates major infrastructure investment and might not be appropriate for all types of cars.

Solar roadways:

In order to provide electricity that may be used to charge electric cars (EVs) while they are in motion, a method known as solar roadways involves embedding solar panels onto the surface of the roads. The solar panels are often comprised of photovoltaic cells, which transform sunshine into electricity. This electricity is then transmitted to the EVs by a charging pad or coil buried in the pavement. Due to their ability to produce electricity from sunshine and lessen EVs’ reliance on grid power, solar highways have the potential to offer a sustainable and green charging alternative. There are, however, a number of technical and practical issues that must be resolved, such as maintaining the solar panels’ dependability and security in the face of heavy traffic and unfavorable weather conditions and creating charging standards that are compatible with various EV models. The price of building and maintaining the solar highways could also prevent their widespread use.

When Will EVs Be Able to Charge While Driving?

Electric vehicle (EV) drivers will soon have the exciting option of charging their vehicles on the go, which could completely change the EV market. Although there are continuing research and development projects in this field, it is challenging to pinpoint a precise time frame for when we should anticipate this technology to become widely used.

To enable EVs to charge while driving, two approaches are being investigated: dynamic wireless charging and conductive charging. However, it will probably take several years to build a standardized charging infrastructure that can serve various EV models and guarantee compatibility across various nations and regions. Dynamic wireless charging is currently being explored in several pilot projects. While conductive charging is being tested as well, there are still technical and safety issues that must be resolved before it can be used as a practical method of charging EVs while operating a vehicle.


In conclusion, the capability for electric vehicles (EVs) to charge while operating on public roads is a promising idea that has the potential to completely transform the EV sector. In order to provide this functionality, technologies like dynamic wireless charging and conductive charging are being investigated; however, these technologies are still in the early phases of development, thus it may take a while for them to become widely used. Nevertheless, ongoing research and development initiatives indicate that this technology has the potential to significantly improve the comfort and usefulness of EVs, making them a more attractive substitute for conventional gas-powered vehicles. Innovation in EV charging solutions will likely remain a focus of active study and investment as we progress towards a more sustainable future.
