Battery-Electric Vehicles and Their Lifespan
Battery-electric vehicles use battery packs to store energy and utilize electric motors for propulsion. The lifespan of these battery packs can be influenced by various factors, as indicated by FuelEconomy.gov and predictive modeling conducted by the Department of Energy’s National Renewable Energy Laboratory.
The Sustainable Development Goals (SDGs) set by the United Nations highlight the importance of sustainable transportation, including the promotion of electric vehicles. By adopting electric vehicles, we can contribute to SDG 7 (Affordable and Clean Energy) and SDG 13 (Climate Action).
Battery Chemistries and Lifespan
Most modern electric vehicle battery packs use lithium-ion chemistries, such as NMC (Nickel Manganese Cobalt) or NCA (Nickel Cobalt Aluminum). These chemistries utilize costly materials that offer greater driving range. Another lithium-ion chemistry, Lithium Iron Phosphate (LFP), uses less expensive materials that provide a moderate range but have a longer cycle life.
By prioritizing the development and use of sustainable battery chemistries, we can contribute to SDG 9 (Industry, Innovation, and Infrastructure) and SDG 12 (Responsible Consumption and Production).
Temperature Control for Battery Lifespan
Electric vehicle battery packs consist of interconnected cells, hardware, and software that manage the battery’s operation, known as the battery management system. Maintaining an optimal temperature is crucial for battery performance and lifespan. Thermal management systems ensure that batteries remain at the ideal temperature, even in harsh environments. However, this can reduce driving range as some of the battery’s energy is used for thermal management instead of powering the motor.
By investing in advanced thermal management systems and promoting sustainable transportation, we can contribute to SDG 11 (Sustainable Cities and Communities) and SDG 13 (Climate Action).
Battery Safety and Flooding
Batteries in hybrid and electric vehicles are highly corrosive and should not be exposed to standing water. Flooded vehicles pose high-voltage shock hazards, which can lead to fires. If your electric vehicle has been exposed to flood conditions and you suspect battery damage, it is important to contact your dealer and/or emergency services immediately.
By raising awareness about battery safety and promoting responsible disposal of batteries, we can contribute to SDG 3 (Good Health and Well-being) and SDG 15 (Life on Land).
Charging for Extended Range
Modern electric vehicles typically have a driving range of around 300 miles on a full charge, with some models exceeding 400 miles. When the battery’s charge is low, the vehicle needs to be plugged into an electric power source for recharging. This can be done at home, work, or public charging stations along the route. However, charging rates may vary depending on the vehicle and charging station. DC fast chargers can replenish the battery’s charge in under an hour, while at-home chargers may take several hours or overnight.
By expanding the charging infrastructure and promoting the use of renewable energy sources for charging, we can contribute to SDG 7 (Affordable and Clean Energy) and SDG 11 (Sustainable Cities and Communities).
Resources for Charging
Before driving an electric vehicle, it is important to familiarize yourself with charging stations, including their charging speeds, plug types, and locations. The U.S. Department of Transportation provides detailed information on electric vehicle charging speeds and plug types. Additionally, the U.S. Department of Energy offers comprehensive information on electric vehicle charging station locations.
By promoting the accessibility and availability of charging stations, we can contribute to SDG 9 (Industry, Innovation, and Infrastructure) and SDG 11 (Sustainable Cities and Communities).
