To preserve battery health, one of the primary guidelines is to follow the 20-80% rule: keep the battery charged between 20% and 80% of its total capacity. Many experts recommend this range to avoid the stress that higher charges place on the battery’s end components. Charging up to 100% should only be done if absolutely necessary, such as before a long journey.

Avoiding Deep Discharges

Deep discharges significantly stress the battery. This can cause mechanical wear on battery cells, leading to a shorter lifespan. It’s advisable to recharge before the battery drops below 20%. Continuous monitoring of the battery’s State of Charge (SoC) helps in planning timely recharges, reducing the frequency and impact of deep discharges.

Managing Temperature Extremes

Batteries are sensitive to temperature extremes. Extended exposure to high temperatures can lead to accelerated degradation, while extreme cold can reduce range temporarily. For best results, park the vehicle in shaded or climate-controlled areas, especially in extremely hot or cold environments.

Avoid Excessive Fast Charging

While Level 3 DC fast charging offers convenience, it should not be used daily. The high power of fast chargers can stress the battery more than Level 1 or Level 2 charging. Instead, it’s better to use slower charging methods when possible.

Monitoring Battery Health

Regular inspections and diagnostic checks are critical to identifying potential issues early. Monitoring the battery’s State of Health (SoH) can pre-empt catastrophic failures and extend service life. Annual electric vehicle maintenance schedules should include these checks to ensure optimal performance.

Proper battery maintenance is essential for maximising the operational life and efficiency of EVs.

Unlike traditional friction-based braking systems in internal combustion engine (ICE) vehicles, regenerative braking captures energy that would otherwise be wasted as heat.

Mechanism of Regenerative Braking

During regenerative braking, the electric motor switches roles to act as a generator. When the driver releases the accelerator or applies the brake pedal, the system captures the kinetic energy from the wheels and converts it back into electricity. This reversed process slows the vehicle down while recharging the battery simultaneously.

Benefits of Regenerative Braking

The primary benefits of regenerative braking for EVs include:

  • Extended Brake Life: Since regenerative braking provides a significant portion of the braking force, traditional brake pads and rotors experience reduced wear and tear. This results in longer intervals between servicing and replacements, ultimately reducing maintenance costs.
  • Enhanced Efficiency: By recapturing kinetic energy, regenerative braking helps improve the overall energy efficiency of the vehicle. This process ensures that more energy is available for propulsion, thereby increasing the driving range.
  • Reduced Environmental Impact: Leveraging regenerative braking decreases reliance on friction brakes. This not only minimises the production of brake dust particles but also reduces emissions associated with brake replacements.

Comparison to Traditional Braking Systems

Compared to the friction-based brakes found in ICE vehicles, regenerative braking systems in EVs offer distinct advantages. Traditional friction brakes convert kinetic energy into heat, resulting in wasted energy and significant wear on brake components. In contrast, regenerative braking conserves energy and reduces the frequency and cost of brake maintenance.

Potential Drawbacks

Despite the advantages, regenerative braking systems can have potential drawbacks. For instance:

  • Lower Effectiveness at Low Speeds: Regenerative braking is less effective at lower speeds, as the system captures less kinetic energy.
  • Complexity and Cost: Adding an electric motor and associated components makes regenerative braking systems more complex and potentially costlier than traditional systems.

Regenerative braking is a critical component of electric vehicles that improves energy efficiency and reduces brake wear. Although it may be complex and less effective at low speeds, the system’s contributions to extended range and reduced maintenance costs make it a valuable innovation in automotive technology.
