The Real Problems with Electric Cars: 10 Key Issues Explained

Electric vehicles (EVs) have gained significant popularity in recent years, but they come with their own set of challenges. This article explores 10 key issues that EV owners face, providing an honest look at the current state of electric car technology.

1. Charging Complexities

Charging an electric car is not as straightforward as filling up a gas tank. There are several factors that complicate the charging process:

Charging Losses

When charging an EV, not all the energy from the grid makes it into the battery. There are transmission losses and energy used to run pumps and cooling systems. This means you're paying for energy that doesn't go towards propelling the vehicle or powering its systems. These losses can range from 8% to 12% during DC fast charging.

Charging Curve

The charging speed of an EV is not constant. It's fastest when the battery is at a low state of charge (typically between 0-30%) and slows down as the battery fills up. This means that the miles added per minute of charging decreases the longer you charge, making it less efficient to charge to 100%.

Temperature Dependence

Charging speed is highly dependent on battery temperature. If the battery is too cold or too hot, it can charge much slower or not at all. Many EVs now have battery preconditioning features to warm up the battery before reaching a charging station, but you need to remember to use this feature.

Infrastructure Reliability

While not directly related to the vehicle itself, the reliability of public charging infrastructure is a significant concern for EV owners. Broken or malfunctioning chargers can lead to frustrating experiences, especially on long trips.

2. Range Variability

The range of an electric car is far more variable than that of a gas-powered vehicle:

Highway Range Loss

EVs typically have lower range at highway speeds compared to city driving. This is due to increased aerodynamic drag at higher speeds and the inability to recapture energy through regenerative braking.

Environmental Factors

Factors like temperature, wind, elevation changes, and even road surface can significantly impact an EV's range. This variability can make trip planning more challenging.

Rated vs. Real-World Range

The EPA-rated range of an EV is often difficult to achieve in real-world conditions, especially at highway speeds. This can lead to disappointment and range anxiety for new EV owners.

Infrastructure Limitations

Even if an EV has a long range on paper, the actual usable range is often limited by the availability of charging stations. You may need to stop and charge before reaching the vehicle's maximum range to ensure you can make it to the next charger.

3. Battery Management System (BMS) Sway

The Battery Management System in an EV is responsible for estimating the state of charge and available range. However, it's not always accurate:

Inaccurate Readings

The BMS can sometimes provide inaccurate readings, especially after repeated charging and discharging cycles. This can lead to unexpected loss of power or overestimating the available range.

Calibration Requirements

Some EVs require periodic full charges or specific charging patterns to recalibrate the BMS. This adds an extra layer of complexity to vehicle maintenance that doesn't exist with gas-powered cars.

4. Winter Performance

Cold weather can significantly impact EV performance:

Reduced Range

Cold temperatures reduce battery capacity and increase energy consumption for cabin and battery heating. This can lead to range reductions of 20-40% or more in very cold conditions.

Slower Charging

Cold batteries charge more slowly, which can extend charging times significantly in winter.

Preconditioning Necessity

To mitigate cold weather effects, EVs often need to be preconditioned (warmed up) while still plugged in. This requires planning and may not always be possible.

5. Phantom Drain

Phantom drain refers to the loss of battery charge when an EV is parked and not in use:

Standby Power Usage

Many EVs use power for systems like app connectivity, security features, and battery management even when parked. This can lead to noticeable battery drain over time.

Temperature-Related Losses

Extreme temperatures (both hot and cold) can cause increased phantom drain as the battery management system works to maintain optimal battery temperature.

6. Battery Degradation

All EV batteries degrade over time, leading to reduced range and performance:

Capacity Loss

Most EVs will lose some battery capacity over time, typically 10-20% over the first 100,000 miles. This gradual loss of range can be concerning for owners.

Factors Affecting Degradation

Degradation can be accelerated by factors like frequent fast charging, extreme temperatures, and consistently charging to 100% or discharging to very low levels.

Warranty Considerations

While most EV batteries are warrantied for 8 years or 100,000 miles, the warranty typically only covers degradation beyond 70% of original capacity. This means some loss is considered normal and not covered.

7. Service and Repair Challenges

Servicing and repairing EVs can be more complex and expensive than traditional vehicles:

Limited Repair Options

Many independent repair shops are not yet equipped or trained to work on EVs, limiting repair options and potentially increasing costs.

Expensive Repairs

Certain EV components, particularly the battery pack, can be extremely expensive to replace if they fail out of warranty.

Specialized Training

EV repairs often require specialized training and equipment, which can lead to longer wait times for service, especially at dealerships with limited EV-certified technicians.

8. Higher Depreciation

EVs often depreciate faster than comparable gas-powered vehicles:

Rapid Technology Advancement

Fast-paced improvements in EV technology can make older models less desirable, leading to quicker depreciation.

Battery Concerns

Uncertainty about long-term battery life and potential replacement costs can negatively impact resale values.

Incentive Effects

Heavy incentives on new EVs can artificially inflate initial prices, leading to steeper depreciation when the vehicle is resold without those incentives.

9. Performance Driving Limitations

While EVs can offer impressive acceleration, they face challenges in sustained performance driving:

Thermal Management

High-performance driving can quickly heat up EV batteries and motors, leading to power reductions to protect components.

Track Day Challenges

Many EVs struggle with consistent performance over extended track sessions due to heat buildup and power limitations.

Range Reduction

Performance driving dramatically reduces range, which can be problematic on twisty roads far from charging stations.

10. Towing Challenges

Towing with an EV presents unique difficulties:

Significant Range Reduction

Towing a trailer can reduce an EV's range by 50% or more, necessitating much more frequent charging stops.

Charging With a Trailer

Many charging stations are not designed to accommodate vehicles with trailers, making it difficult or impossible to charge without unhitching.

Extended Charging Times

The need to charge to higher levels when towing (often 90-100%) significantly extends charging times, making long trips with a trailer much more time-consuming.

While electric vehicles offer many benefits, it's important for potential buyers to be aware of these challenges. As EV technology continues to evolve, many of these issues are likely to improve. However, for now, they remain important considerations for anyone looking to switch to an electric vehicle.
