The Safety of Electric Vehicles for Fleets

For fleet owners and operators looking to cut down on costs, electric vehicles (EVs) present an appealing option. However, transitioning from familiar internal combustion engine (ICE) vehicles to EVs raises concerns about safety. The good news is that EVs are not only as safe as their ICE counterparts but, in several aspects, they offer enhanced safety features. Let’s dive into what makes EVs a secure choice for fleets.

Safety Standards for Electric Vehicles in Fleet Operations

Electric vehicles (EVs) are subject to rigorous safety standards and testing protocols, ensuring they are on par with traditional internal combustion engine vehicles in terms of safety. The United States Environmental Protection Agency (EPA) mandates that all light-duty cars and trucks sold in the country, including EVs, comply with the Federal Motor Vehicle Safety Standards. These standards require vehicles to pass a comprehensive series of tests, irrespective of their power source.

EVs undergo specific scrutiny, especially regarding their battery packs, which are tested against stringent standards to ensure safety under various conditions. In addition to meeting general vehicle safety standards, EVs incorporate advanced safety features designed to protect passengers by automatically shutting down the vehicle’s electrical system in the event of a collision or short circuit.

To assist consumers and fleet operators in monitoring vehicle safety, resources such as Kelley Blue Book’s tracking webpage and the National Highway Safety Administration’s VIN search offer tools for tracking vehicle recalls and safety compliance. This comprehensive approach to safety certification underscores the reliability and security of integrating EVs into fleet operations.

Electric Vehicle Safety in Fire Incidents

Electric vehicles (EVs) have been under scrutiny regarding their safety in fire incidents, yet evidence suggests they are less prone to catching fire compared to internal combustion engine (ICE) vehicles. Data indicates that EVs are significantly safer in terms of fire risk. For instance, in Norway, where electric cars are more prevalent than anywhere else in the world, petrol and diesel car fires occur four to five times more frequently than those involving electric vehicles, as reported by The Guardian.

EVs are engineered with numerous fire suppression features aimed at both preventing fires from initiating and containing them if they do occur. One key safety advantage of EVs in collisions is the absence of liquid fuel, which eliminates the risk of leaks and subsequent fires.

However, it’s important to acknowledge that when EV fires do occur, they can burn hotter and for a longer duration due to “thermal runaway,” a process triggered by the battery’s chemicals. Despite this, there are established protocols and training programs, such as those provided by the National Fire Protection Association (NFPA) in the U.S., designed to equip first responders with the necessary skills to handle these less common but more intense fires. This comprehensive approach to safety and emergency preparedness further enhances the overall safety profile of EVs in fire scenarios.

Electric Vehicle Safety for Pedestrians

Electric vehicles (EVs) bring a unique concern to pedestrian safety due to their quiet operation. Unlike internal combustion engine (ICE) vehicles, EVs produce very little noise, particularly at low speeds, making it harder for pedestrians and cyclists to notice them approaching. This quiet nature, while a benefit in reducing noise pollution, poses a potential risk to those outside the vehicle.

Recognizing this issue, various governments around the world, including the United States, Canada, and the European Union, have implemented regulations requiring EVs to be equipped with noise-emitting devices at low speeds to alert pedestrians of their presence. These low-speed noise emitters produce sounds that compensate for the lack of engine noise, enhancing safety for pedestrians and cyclists.

Initially, automakers had the flexibility to create custom sounds for their vehicles. However, to ensure consistency and effectiveness in alerting pedestrians, the United States’ National Highway Safety Administration (NHTSA) standardized the low-speed hum in 2022. This measure aims to safeguard pedestrians by making EVs more audible, particularly in urban environments where low-speed interactions are frequent.

Environmental Safety of Electric Vehicles

Electric vehicles (EVs) are widely recognized for their environmental benefits, primarily because they emit no tailpipe pollutants and generate less noise compared to traditional internal combustion engine (ICE) vehicles. These characteristics make EVs inherently safer for the environment during their operational phase.

However, it’s important to consider the full environmental impact of EVs, including the greenhouse gas (GHG) emissions produced during their manufacturing process. Additionally, the source of electricity used to charge EVs plays a significant role in determining their overall environmental footprint. This concept, known as “well-to-wheel emissions,” encompasses both the emissions from vehicle production and the electricity generation used for charging.

Despite these considerations, the U.S. Environmental Protection Agency (EPA) notes that when evaluating the total lifecycle emissions—from manufacturing through charging to driving—EVs typically have a lower GHG emission profile than gasoline-powered cars. This assessment confirms that EVs, over their entire lifespan, offer a more environmentally friendly option, contributing to a reduction in overall GHG emissions and aiding in the efforts to combat climate change.

What Makes EVs a Safer Choice?

EV Stability: Low Center of Gravity

Electric vehicles (EVs) boast a lower center of gravity due to the placement of heavy battery packs at the vehicle’s base. This design greatly reduces the risk of rollovers during a collision, offering a significant safety advantage. This feature is particularly beneficial for fleet vehicles that often bear heavy loads, potentially increasing the risk of top-heavy instability.

EV Maintenance: Less Is More

Electric vehicles (EVs) offer a significant safety and maintenance advantage over internal combustion engine (ICE) vehicles due to their simpler construction, which includes far fewer moving parts. With only about 20 moving components in EV motors and drivetrains, in contrast to the roughly 2,000 found in a typical ICE vehicle, EVs present lower risks of mechanical failures.

Moreover, EVs benefit from slower wear on friction brake components such as pads, rotors, and shoes. This is attributed to the integration of regenerative braking systems that use the vehicle’s motor to decelerate, effectively running it in reverse to recapture energy and feed it back into the battery, providing a slight increase in range. This innovative braking method allows EVs and hybrids to extend the intervals between brake maintenance services to around 100,000 miles, significantly reducing upkeep requirements and enhancing vehicle safety.

EV Torque: Instant Acceleration

Electric vehicles (EVs) possess a unique advantage in emergency situations or when quick maneuvers are necessary, thanks to their instant torque capability. According to Car and Driver, numerous mainstream EVs, including sedans and SUVs not specifically designed for high performance, can accelerate from zero to 60 mph in under 5 seconds. Impressively, some models have achieved this in less than 3 seconds, placing them in supercar acceleration territory despite being electric.

This swift acceleration contrasts sharply with the inherent delay experienced in internal combustion engine (ICE) vehicles, which undergo a multi-step process to convert fuel into motion:

  1. The driver presses the gas pedal.
  2. This action turns a pivot, pulling the throttle wire.
  3. The wire then activates a throttle linkage.
  4. The linkage opens a valve to let air into the engine.
  5. Fuel is injected into the engine.
  6. The engine completes a four-stroke cycle (intake, compression, combustion, exhaust) to generate power.
  7. Combustion moves the pistons, which in turn drive the crankshaft.
  8. The crankshaft, connected to the transmission, regulates power to the wheels.
  9. Finally, the drive shaft turns, rotating the vehicle’s wheels.


In contrast, EVs bypass these steps by directly converting electrical energy into motion, allowing for maximum torque application from zero RPM without the need for a traditional transmission. This results in a nearly flat torque curve, offering optimal acceleration from a standstill to high speeds. Furthermore, many EVs feature all-wheel drive, with individual motors for each wheel, enhancing their ability to quickly and safely merge or evade danger.

For fleet operations, this means drivers have the capability to rapidly accelerate out of potentially hazardous situations, providing a significant safety advantage. The absence of a delay in power delivery ensures that fleet drivers can rely on their vehicles to perform immediately when needed, making EVs an increasingly attractive option for fleet efficiency and safety.

EV Safety: Advanced Features

Electric vehicles (EVs) boast several advanced safety features, including automatic emergency braking, lane departure warnings, adaptive cruise control, and blind spot monitoring. These technologies aim to reduce driver errors and fatigue.

Automatic emergency braking activates to prevent collisions, lane departure warnings signal when veering off course, adaptive cruise control maintains safe distances, and blind spot monitoring warns of unseen objects. Together, these features enhance driving safety. However, it’s important for drivers to stay attentive and in control, even with these aids.

The Driving Range of Modern Electric Vehicles

Range anxiety, once a significant concern for electric vehicle (EV) drivers, is gradually being replaced by range confidence. This shift is due to the expanding network of public charging stations, which now boasts over 72,000 locations and nearly 200,000 charging ports across the United States and Canada. With continuous technological advancements and an increasing number of businesses installing public charging stations, the fear of running out of battery power is becoming less of an issue for EV owners.

Conclusion

For fleet operators prioritizing safety, the transition to electric vehicles (EVs) presents a clear advantage. With their enhanced safety features, lower maintenance requirements, and increasing range confidence, EVs offer a compelling case for replacing traditional internal combustion engine fleets.
