The life of an electric vehicle (EV) battery refers to its lifespan or durability over time. Several factors influence the life of an EV battery:

1. **Chemistry**: EV batteries are typically lithium-ion batteries, but there are different variations in chemistry. The specific chemistry used in the battery affects its lifespan. Some chemistries degrade faster than others.

2. **Usage Patterns**: How an EV is driven and charged can significantly impact battery life. Aggressive driving, frequent fast charging, and deep discharges can all accelerate battery degradation.

3. **Temperature**: Extreme temperatures, both hot and cold, can negatively impact battery life. High temperatures accelerate chemical reactions in the battery, leading to faster degradation, while cold temperatures can reduce battery performance temporarily.

4. **Charging Practices**: Charging an EV battery to full capacity and leaving it at a high state of charge for extended periods can contribute to degradation. Similarly, frequent fast charging can put additional stress on the battery.

5. **Battery Management Systems (BMS)**: The effectiveness of the battery management system in monitoring and regulating the battery’s temperature, voltage, and state of charge can impact battery life. A well-designed BMS can help prolong battery life by optimizing charging and discharging processes.

6. **Manufacturer Warranty**: Most EV manufacturers offer warranties on their battery packs, typically covering a certain number of years or miles. This warranty often guarantees a minimum level of performance and degradation over the warranty period.

Overall, advancements in battery technology and ongoing research aim to improve the longevity and durability of EV batteries. With proper care and maintenance, EV batteries can provide reliable performance over many years of use.
