Driving down the road today, one sees a big increase in electric vehicles (EVs) as more and more drivers are buying them for different reasons. These reasons include more models from manufacturers, cheaper options including pre-owned cars, environmental benefits and new technology. However, with their growing popularity, owners and potential owners of EVs need to consider the pluses and minuses of driving an EV including insurance and their overall safety-especially from battery fires.

Pros and cons of owning an electric vehicle

Some of the benefits of owning an electric vehicle include helping the environment. EVs release less pollution than regular cars, which means there is less tailpipe air pollution than regular vehicles. Another benefit is lower costs to run, as charging an electric vehicle usually costs less than fueling a gas-powered car. This is especially true for people who have home charging stations or can use low-cost public charging stations. EVs also have fewer moving parts than internal combustion engine vehicles, which can result in lower maintenance and repair costs. EVs have advanced technology, including features like regenerative braking, smart driver-assistance systems and many new hi-tech options. Drivers find these features appealing because they can make driving safer and more enjoyable.

Some of the problems with owning an electric vehicle include higher purchase prices. Electric vehicles are usually more expensive than gas-powered cars, even with government incentives and a more competitive market for new and used models. And while EV range is improving, some models still offer less driving range on a single charge compared to a full tank of gasoline. Charging infrastructure also varies by region, and long road trips may require careful planning to ensure charging station availability. Charging an EV takes longer than filling a gas tank, even with rapid chargers, and charging during a trip might require waiting, which can be inconvenient. Another downside is the cost of insurance which is more expensive. We will cover that topic next.

Insuring an electric vehicle

In general, insuring an EV for most drivers is the same as insuring a gasoline-powered car. Most insurance companies don’t have concerns about EV’s that would make them limit or exclude them from a policy. However, due to their generally higher purchase prices, expensive battery components and substantial technology, EVs often carry higher insurance premiums than conventional vehicles. Repair costs for EVs, particularly for the battery as well as all the additional technology inside and outside the car can also be more substantial. Replacement parts can take a while to get delivered, slowing down the repair process, which adds more cost. All these reasons can increase insurance rates charged by the insurance company. On top of that, recently there have been some losses due to battery fires caused by flooding that have insurers looking more closely at this potential risk for loss. In the next section we’ll review battery fire risk in more detail.

Understanding the risks of battery fires in electric vehicles

The safety of EV batteries, particularly concerning fire risks, is an important consideration for potential buyers. EVs use lithium-ion batteries, known for their energy density and ability to provide substantial power. However, these batteries also carry some fire risk, primarily due to the following factors:

  • Thermal Runaway: A thermal runaway occurs when a lithium-ion battery cell overheats, leading to a chain reaction that can cause nearby cells to ignite. Thermal runaway can be triggered by a defect, physical damage to the battery, exposure to extreme temperatures, and flooding.
  • Charging and discharging issues: Improper charging, such as overcharging or using a non-certified charger, can lead to overheating, which increases fire risk. EVs generally have advanced battery management systems to prevent such issues, but owners must follow proper charging practices.
  • Accident damage: A severe collision or impact can damage the EV battery, sometimes leading to a short circuit that results in a fire. While EVs are designed with protective structures around the battery pack, high-impact accidents can still pose a risk.
  • Manufacturing defects: Although rare, defects in battery manufacturing or assembly can increase the risk of fire. Such risks are generally covered under warranty or recall policies, but defects have historically led to fires in some EV models.
  • Water damage causing a fire: Lithium-Ion batteries can catch fire because of water damage or flooding. The water causes a chemical chain reaction (thermal runaway) in the battery that could cause it to burn. In recent storms and hurricanes, some electric vehicles that were in flood waters caught fire. The fire destroyed the car and started a fire in the garage causing the home to burn down. These types of fires are difficult to extinguish due to their complex chemical reaction and take fire fighters with special training and equipment to suppress a fire.

EV manufacturers are improving battery safety and fire suppression systems. They are adding features to stop fires and make it less likely that they will start. EV owners should also take preventative measures when there is a storm approaching with flooding likely to move their car out of harm’s way. Fortunately, EV battery fire incidents remain relatively rare compared to gasoline vehicle fires, which are more common but typically less publicized.

Conclusion

Owning an electric vehicle has its benefits, from environmental advantages and lower operating costs to advanced technological features. However, challenges like higher purchase prices, limited range and higher insurance costs should be weighed when deciding if an EV is right for you. When it comes to safety, battery fire risk is a legitimate concern, and it’s important to know the risk and take action to minimize those risks.
