One of the most innovative and exciting advancements in the automotive world is the development of electric vehicles, and Tesla has played a significant role in pushing these environmentally friendly cars into the mainstream.
Understanding the factors that impact battery life becomes essential when owning an electric vehicle.
Quick Answer:
A Tesla can generally sit for about two weeks without substantial battery loss, though this can vary with factors like model, battery age, charge state, and energy settings. The “Energy Saving” mode can help extend battery life when the car is idle.
A Tesla, like any other EV, depends on its battery pack to store and provide energy for both driving and running onboard systems.
When parked and not in use, the vehicle still consumes a small amount of energy to maintain these vital systems, which can eventually drain the battery if left unattended for extended periods.
Tesla Battery Basics
Lithium-Ion Batteries
Tesla electric vehicles use lithium-ion batteries similar to those found in laptops and smartphones. These batteries have a high energy density and can store a lot of energy in a relatively small space. Unlike traditional gasoline cars, electric vehicles like Teslas rely on battery power to keep moving.
Battery Capacity
Tesla offers different battery capacity options for its vehicles, measured in kWh (kilowatt-hours). Battery capacity determines how much energy the battery can store and directly impacts the vehicle’s range.
For example, a Model 3 with a Standard Range Plus battery has an estimated range of 263 miles, while a Long Range version extends that number to 353 miles. The larger the battery capacity, the longer distance a Tesla can travel without needing to recharge.
Battery Life
Over time, the battery life of a Tesla may decrease due to various factors, such as charge cycles and temperature fluctuations. However, Tesla has designed its batteries to endure daily use for many years.
While battery degradation is inevitable, most Tesla owners report losing only about 5-10% of their battery capacity after 100,000 miles.
To maximize battery life, Tesla recommends:
