Just How Safe Are Electric Vehicle Batteries?

Numerous potential electric vehicle (EV) owners are put off by anxiety, while others have concerns about its battery safety. Regardless of these doubts, learning the range of security features guiding you as an EV user can offer a sigh of relief.

The lithium-ion battery in electric vehicles can catch fire and is combustible due to its power cells, potentially leading to short-circuiting and damage. However, electric vehicle batteries have minimal chance of fire or explosions compared to the gasoline present in conventional vehicles.

Unsafe electric vehicle batteries result from packing high voltage electric systems, raising concern with users. Read on to learn the safety features of electric vehicle batteries.

Potential Hazards in Electric Vehicle Batteries

Even though automotive designers still work hard towards improving and advancing the safety of lithium-ion batteries, there are some earlier failure concerns.  As an electric vehicle lover, you should have information on some expected battery failures. For instance, such situations include:

  • Low-temperature charging conditions- In cases of intercalation, lithium deposits as metal on the anode surfaces.
  • Heat dissipation– It causes a faster rate of generation of heat than dissipation.
  • Crash consequences– The high voltage deformation could lead to the failure of the operation.
  • Thermal runaway events– Short circuits are standard if one of the cells inside gets damaged. Flammable electrolytes inside could become hotter, igniting inside, causing a fire and increased temperatures due to stored energy. Further, the fire could spread to other cells causing a high flame inside.
  • Cell stress effects– It results in expanding the cathode and anode materials, causing stress on the cells.
  • Crash consequences– High-profile EV accidents leading to the cars burning a few years ago resulted in nervousness amongst car buyers. One would think that gas vehicles are more prone to such accidents, but electric cars can also encounter combustion after a collision.
  • Aging in the vehicle environment– Electric vehicle batteries also suffer from degradation caused by the vehicle’s age or environment.

Latest Generation Electric Vehicle Battery Safety Features

The latest generation electric vehicle offers additional safety standards that solve the terrifying dangers of its battery. A crash-resistant structure protects the battery, for starters, fitted at a place far away from the potential impact areas and a section as low in the car as possible.

For example, Polestar has two deformable aluminum structures on either front bulkhead and recently launched two models. In addition, a severe partial offset crash protects the front wheels that might strike the batteries during a frontal collision.

Modern generation electric vehicles come with individual cells surrounded by advanced phase change materials, reducing the risk of overheating by helping absorb heat on nearby cells. In addition, electric cars have unique features guaranteeing that occupants in an emergency evade shock if an accident occurs.

In the event of a crash, electric vehicles include safety systems to isolate the battery automatically. A car’s sensors determine if a collision would find special pyro fuses and effectively disconnect all power. In addition, automotive specialist manufacturers like Bosch developed systems that drive small wedges into the cables in airbag triggers.

Charging Your Electric Battery Safely At Home

Here are quick safety tips in case you decide to charge your electric vehicle at home:

  • Use vehicle charging adaptors supplied by electric vehicle supply equipment manufacturers only.
  • Avoid using household adapters like a double plug, multi-box, or travel plug, between the protection devices and in-cord control or a socket control.
  • Please avoid using faulty charging equipment but instead, get it checked up by the manufacturers prior.
  • Avoid using modified or damaged charging equipment.

As batteries improve and their capacities increase, they are likely to require a longer charging time. A dedicated wall-mounted plug unit at home would guarantee you safe charging. The high-powered EVSE chargers guarantee to charge bigger electric vehicle batteries. The units ensure sufficient charging within a short duration.

Recommended Electric Vehicle Battery Charging Items

Keep in mind the suitable types of electric vehicle battery charging devices for enhanced safety:

  • Electric vehicle Supply Equipment– It includes items used to charge electric vehicles like socket outlets or supply leads.
  • Protection Device (IC-CPD) – This device performs safety and controls function like shutting power off in case of problems.
  • Residual Current Device (RCD) – This switches off electricity permanently in case there is a problem.
  • EV Adopter– This allows cars having different connections to make use of charging equipment.
  • Type BRCD– This adopter handles different types of faults EVs and EVSEs places on home warning.

The safety precautions of these items attribute to guaranteed wellbeing when using electric vehicle batteries.

Is it Safe to Charge an Electric Battery in The Rain?

Many potential electric vehicle buyers wonder if electricity and water would mix when charging a high voltage car system. The reality is surprising due to the unique design used on the electrical plug.

The socket and plug in the vehicle assure that there is no opening for dirt or water particles. Further, the available charging systems are weatherproofed.

The onboard systems installed in the cars and chargers are highly sophisticated, not allowing a flow of electricity into the vehicle until the performance of several checks. These checks can confirm the presence of water in the connections. Regardless of the weather, it is easy to plug in the chargers on electric batteries.

Electric Vehicles Are Manufactured to Be Just As Safe As Gas (If Not Safer)

Electric car builders focus on electric cars with similar strict manufacturing and design regulations as their diesel and petrol counterparts. Further, they uphold the steps, careful process, and the optimum time to guarantee the machine’s peek safety.

Further, they subject the electric vehicle to assessment by Euro ENCAP, aiming at highlighting and proving their hard work. Electric cars have some of the proceeding safety features:

  • Extensive crumple zones
  • Strong structures
  • Multiple airbags
  • The extra mass of battery packs

Therefore, the need to absorb increased energy created during collisions is met through the features. In addition, the features show that EV designers work even harder to meet the safety guidelines and acquire unique crashworthiness set by vehicle safety organizations.

Presence of Noise Emitters in Electric Batteries- Fitted Cars

Apart from the safety concerns users of electric vehicles might have, cyclists and pedestrians have noise-related safety concerns since the battery is a lot quieter than a gas engine. They have a more challenging time hearing these nearly silent vehicles, which can be problematic at crosswalks and near bike lanes. Electric cars can alleviate these concerns with an electronic noise emitter installation.

Recent vehicle manufacturing requires electric cars to fit a rear and front device that generates sounds at a frequency equal to an internal combustion engine at equal speed.  The effect is felt when the car is manoeuvring and parking too, emitting a low whine.


Manufacturers of electric battery-run vehicles match its safety to gas or diesel car builders. Electric vehicle builders work even harder by installing safety features that guard their users.

Modern manufacturers fit the electric vehicle with batteries with enhanced safety features contrary to the older models that caused fires or total failure. By following the charging safety precautions, electrically-run cars are safe with their electric batteries.
