Understanding EV Battery Basics

What is an EV Battery?

At the heart of every electric vehicle (EV) is its battery, typically a lithium-ion battery. These batteries are similar to those in your smartphone or laptop but much larger and more powerful. An EV battery consists of many cells grouped into modules, which are then combined to form the complete battery pack. These cells store energy chemically and release it as electrical power to drive the vehicle’s electric motor.

Battery Capacity and State of Charge (SoC)

To understand why charging to 80% is beneficial, it’s important to grasp the concepts of battery capacity and state of charge (SoC).

  • Battery Capacity: This refers to the total amount of energy a battery can store, usually measured in kilowatt-hours (kWh). For example, a battery with a capacity of 60 kWh can theoretically provide 60 kilowatts of power for one hour before being fully depleted.
  • State of Charge (SoC): SoC represents the current level of charge in the battery as a percentage of its total capacity. If your EV’s battery is at 80% SoC, it means it’s 80% full and has 80% of its total capacity available for use.

Understanding these terms helps in appreciating how different charging practices impact the battery’s health and performance over time.

The Science Behind Charging to 80%

Battery Degradation

Battery degradation is a natural process where a battery’s ability to hold a charge diminishes over time. Various factors contribute to degradation, including temperature, charging habits, and how deeply the battery is cycled (charged and discharged). Charging to 100% can accelerate this process because it stresses the battery more than charging to 80%.

Chemical Stress and Heat Generation

When a battery is charged to its full capacity, it undergoes increased chemical stress. This stress can lead to the growth of unwanted chemical formations inside the battery, which reduces its efficiency and capacity over time. Additionally, charging to 100% generates more heat, further contributing to battery wear and tear.

Charging Cycles and Longevity

The number of complete charge and discharge cycles a battery can undergo before its capacity significantly diminishes is limited. Charging to 100% and discharging to 0% counts as a full cycle, while partial cycles (like charging to 80% and discharging to 20%) are less stressful and therefore extend the battery’s lifespan. Regularly charging to 80%, you reduce the depth of each cycle, thereby preserving the battery’s health.

Charging your EV to 80% is a practical, science-backed approach to maintaining battery health, optimizing performance, and ensuring your vehicle remains efficient and reliable for years to come.

The Science Behind Charging to 80%

Battery Degradation

Battery degradation is an inevitable process where the capacity of an EV battery diminishes over time. This occurs due to the chemical reactions inside the battery cells, which gradually reduce their ability to store and release energy. Charging to 100% can accelerate this degradation process. When a battery is fully charged, the high voltage stresses the battery cells, causing wear and tear at a microscopic level. Over time, this leads to a decrease in the battery’s overall capacity and efficiency.

Chemical Stress and Heat Generation

Charging a battery to its full capacity not only causes chemical stress but also generates excess heat. When a battery is charged to 100%, it undergoes a series of electrochemical reactions that can create unwanted chemical compounds inside the cells. These compounds can form crystalline structures known as dendrites, which can pierce the battery’s internal structure and lead to short circuits or reduced capacity.

Moreover, the process of charging generates heat, and higher states of charge produce more heat. Excessive heat can damage the battery cells, reducing their lifespan and efficiency. When charged to only 80%, the battery experiences less chemical stress and generates less heat, thereby maintaining its health and performance over a longer period.

Charging Cycles and Longevity

Battery longevity is often measured in charging cycles – a full cycle being a complete charge from 0% to 100% and back down to 0%. However, not all cycles are created equal. Charging a battery in smaller increments, such as from 20% to 80%, results in partial cycles, which are less stressful on the battery compared to full cycles.

Partial cycles help preserve the battery’s health by reducing the depth of discharge and the amount of time the battery spends at high voltage levels. Studies have shown that EV batteries that are regularly charged to around 80% can perform significantly better over time compared to those frequently charged to 100%. This is because the battery avoids the extremes of high and low states of charge, both of which contribute to faster degradation.

Optimal Performance Range

EV batteries have an optimal performance range, typically between 20% and 80% SoC. Within this range, the battery operates efficiently and maintains a stable temperature, reducing the likelihood of thermal stress. Charging to 80% keeps the battery within this optimal range, ensuring that it performs reliably and efficiently for daily use.

Maintaining this optimal performance range also means that the battery can deliver consistent power output and energy efficiency, which translates to a better driving experience. Avoiding the upper and lower extremes of charge, helps ensure that your EV remains reliable and performs at its best.
