Power of EVs Lithium-Ion Batteries

Most EVs and Hybrid vehicles, along with consumer electronics like laptops, smartphones, e-cigarettes, and electric scooters, are powered by lithium-ion batteries. Lithium-ion batteries offer a high power-to-weight ratio, meaning they can store more energy relative to their mass and volume. They also feature high energy efficiency, good performance at elevated temperatures, long life, and low self-discharge rates.

In a prototype, the latest invention, the ONE Gemini Battery, is capable of powering electric vehicles (EVs) for 752 miles (1,210 kM) on a single charge. We can expect even more powerful batteries specifically designed for EVs in the near future.

Tesla’s lithium-ion batteries typically utilize high-energy nickel cobalt aluminum (NCA) chemistry. Each individual cell has a capacity of approximately 3,100mAh and a nominal voltage of about 3.6 volts.

The battery capacity of a Tesla Model S varies based on the trim level, ranging from 60 kWh to 100 kWh. For instance, a Model S 70 is equipped with a 70 kWh battery, while the base model features a 100 kWh battery. These lithium-ion batteries are capable of delivering a range of approximately 333 miles (536 kM) on a full charge.

The Model S 90D has a 90 kWh battery, with a nominal voltage of 356 V and a maximum power output of 310 kW. Depending on the specific battery module and the duration of current output, the Tesla Model S battery can generate between 225 and 750 amps.

Dangers of EVs Batteries During Short Circuit

While EV battery compartments are designed to be sealed and well-protected, damage can still occur during accidents. If the battery is punctured or crushed, causing a short circuit between the positive and negative electrodes, it can result in a high current flow. This may lead to severe electric shocks and other risks.

In the event of a short circuit, the stored energy in the battery is released rapidly, generating extreme heat. Temperatures can soar up to 900°C (≈11652°F), which could potentially cause the battery to explode and trigger a hazardous fire.

EV systems typically operate at 400V DC, with newer models reaching up to 1000V DC. Although DC systems pose a lower electrocution risk compared to AC systems, they are not entirely risk-free. Rescuers, emergency responders, and operators need to exercise caution, particularly with the orange high-voltage (HV) cables used in EV traction systems.

Now, consider the immense power of these batteries if their terminals were to be shorted—whether by a metal object like a can opener or damage caused by a sharp object in an accident. Such incidents can lead to dangerous outcomes, including severe electric shocks, fires, or explosions.

This is why it is critical to take proper safety precautions and adhere to established guidelines when handling or working around lithium-ion batteries. Always prioritize safety to prevent accidents.

Can I Get an Electric Shock From an Electric Vehicle?

The short answer is YES! an electric or hybrid vehicle can potentially cause an electric shock

It means, it is possible to get electrocuted by an electric vehicle (EV), but the likelihood is extremely low due to stringent safety features, codes and standards in EV design. Manufacturers prioritize safety to ensure that high-voltage systems are well-insulated, protected, and safe for users. Here’s an explanation of the potential risks and the safety measures in place:

Electric vehicles (EVs) operate with high-voltage batteries, typically ranging from 400V to 1000V, which can be lethal if mishandled. Key components such as inverters, motors, and charging systems are directly connected to these high-voltage circuits, as well as AC charging circuits.

Exposure Due to Crashes or Repairs
In severe accidents or improper repair work, high-voltage cables or components may become exposed or shorted, posing a significant electrocution risk. This is particularly concerning if the battery compartment or its connections are damaged.
Unauthorized Tampering
Maintenance or handling by untrained individuals can result in accidents, including electric shocks or fires. Unauthorized tampering can bypass essential safety mechanisms, increasing the risk of hazards.
Water Intrusion
Although EVs are designed to be waterproof, substantial damage to the vehicle’s seals or components could allow water intrusion. This can lead to electrical shorts, hazardous fires, or electrocution.

Can a Drowned Electric Vehicle in the Water Electrocute You?

If an EV becomes submerged, for instance, in a pool, flood, or during heavy water exposure at the charging port or battery compartment, water is unlikely to penetrate the battery compartment. These compartments are designed to meet strict safety standards. These codes and regulation are provided by National Electric Vehicle Infrastructure (NEVI) standards established by the U.S. Department of Energy, the National Highway Traffic Safety Administration (NHTSA), the Department of Transportation (DOT), and Federal Motor Vehicle Safety Standards (FMVSS).

EVs manufactured in the United States adhere strictly to these regulations. Additionally, Tesla EVs, for example, come equipped with advanced safety features and sensors that automatically disconnect the battery in the event of a crash or rollover.

In cases where an EV is submerged, the first component affected is usually the charging port. Modern EVs are equipped with built-in sensors that detect water or short circuits in the port terminals. Upon detection, the system isolates the affected components to prevent further hazards.

If an EV’s battery terminals are exposed to salty water, a short circuit can occur, affecting the specific area and surface of the water around it. This is similar to what happens when lightning strikes the sea or a power line comes into contact with seawater. The exact affected area is unpredictable and undefined, but anyone near it could be at risk of electrocution.

To date, there have been no verified incidents of rescuers being electrocuted by lithium-ion batteries during collisions, exposure to direct water streams on burning vehicles, or submersion. However, high-voltage components and cabling in EVs still pose electrocution risks if not handled properly. Emergency personnel and operators must remain vigilant to ensure safety.

Warning: Electric vehicles that have been submerged in the saltwater, may have a higher chance of a battery short circuit, which may result in a battery blast and fire.

Safety Measures in EVs

EVs are equipped with multiple safety features to minimize the risks of electrocution:

High-voltage systems are insulated and separated from accessible parts to prevent accidental contact.
Most EVs have a high-voltage safety disconnect mechanism that automatically cuts off the high-voltage system during accidents or during the maintenance and service.
Advanced systems monitor and detects ground faults or leakage currents and shut down the high-voltage system in case of problem detection.
The color coded cables such as high-voltage cables are typically orange, clearly distinguishing them from low-voltage systems.
Compliance with safety standards and regulation like NEC and IEC 61851 (for EV charging) ensures the design minimizes the risk of electrocution.
EV batteries waterproof compartments and other high-voltage components are housed in sealed enclosures that are resistant to water and mechanical damage.
Charging systems are designed with safeguards like automatic shut-off during faults. Similarly, connectors are designed to prevent accidental contact with live parts. Moreover, the special purpose outlet (such as 14 used for EVs charging are GFCI protected.

How to Stay Safe Around EVs

If your EV have been submerged in water, do not attempt to drive it or connect it to the charging point.
Always adhere to the maintenance guidelines and usage instructions provided by the manufacturer.
Only use chargers certified by the manufacturer. Avoid unapproved or damaged charging devices.
Never attempt DIY repairs or maintenance on high-voltage systems. Only trained professionals should work on EV electrical components.
After any collision, ensure the vehicle is inspected by certified technicians to verify the integrity of high-voltage systems.
Pay attention to dashboard warnings and error codes. If an issue is detected, stop using the vehicle until it is serviced by a professional.

By following proper precautions and relying on built-in safety measures, the risk of electrocution from EVs is minimal. These features, combined with responsible handling, ensure a safer experience for drivers and responders alike.
