The Science Behind Battery Degradation
Lithium-Ion Battery Chemistry
Tesla vehicles, like most electric cars, utilize lithium-ion batteries. These batteries work by moving lithium ions between a positive and negative electrode. During charging, lithium ions travel from the external power source to the positive electrode, storing energy. When the car is in motion, the ions flow back to the negative electrode, releasing energy to power the electric motor.
The repeated movement of these lithium ions is what generates the electric current. However, this constant cycling can cause wear and tear on the battery’s internal structure, leading to a gradual reduction in its capacity to hold a charge – a phenomenon known as battery degradation.
Factors Affecting Degradation
Several factors influence how quickly a lithium-ion battery degrades:
- Temperature extremes: Both very hot and very cold temperatures can accelerate battery degradation.
- Depth of discharge (DoD): Deeply discharging a battery, meaning using a significant portion of its stored energy, puts more stress on its components and can lead to faster degradation.
- Charging rate: Fast charging, while convenient, generates more heat within the battery, which can contribute to degradation.
- State of charge (SoC): Lithium-ion batteries tend to degrade faster when they are constantly kept at a high state of charge (e.g., 100%) or a very low state of charge (e.g., 0%).
Charging to 100%: The Potential Risks
Increased Stress on Battery Cells
Charging a Tesla to 100% puts the battery under more stress than charging to a lower percentage. This is because lithium-ion batteries have a limited number of charge cycles before their performance starts to decline.
When you charge to 100%, you’re essentially pushing the battery to its maximum capacity more frequently. Over time, this repeated stress can contribute to faster degradation.
Heat Generation
Charging a Tesla to 100% can generate more heat within the battery pack, especially if you’re using a fast charger. High temperatures accelerate chemical reactions within the battery, which can lead to accelerated degradation.
