The current Tesla battery capacity is 83Kw/h, the density is 200wh/Kg, and the driving range is 480 kilometers.
Tesla batteries can generally be charged and discharged 300-500 times. It is best to partially discharge lithium batteries rather than fully discharge them, and try to avoid frequent full discharges. Once the battery rolls off the production line, the clock starts ticking. Regardless of whether you use it or not, the service life of lithium batteries is only two to three years.
The batteries being studied abroad include lithium-sulfur batteries and lithium-air batteries. Those suitable for battery replacement include zinc-air batteries and aluminum-air batteries. The energy density of lithium-sulfur batteries can reach 2600Wh/kg. Lithium-air batteries The energy density can reach 3500Wh/kg, and the theoretical energy density of aluminum-air battery is 8100Wh/Kg. The rapid power swap methods and devices launched by Tesla are likely to be pre-planned to prepare for future technological monopoly. The current Tesla battery capacity is 83Kw/h, the density is 200wh/Kg, and the driving range is 480 kilometers; even if the density is increased five times to 1000wh/Kg, battery replacement becomes a natural choice.

Car battery life:
The design life of the battery is 27 months. Generally, family cars are relatively economical, and new car batteries are used a lot. 3-4 years, but after replacing it once, it usually must be replaced about 2 years ago. Taxis are relatively expensive, and a single bus lasts for a year or so, while a double bus lasts about 8-10 months.
Several factors that affect battery life are: vehicle condition, road conditions, and driver’s habits.
Generally, the newer the car, the more battery it saves, because the motor is easy to use and saves battery, and the generator is easy to use and the battery can be fully charged. When the car gets old, especially after the two large parts of the motor and generator are replaced, Due to the huge price difference between original and refurbished products of these two products on the market, it is easy for car owners not to replace the original parts, and then the battery will be more likely to break.
Off-road batteries are often damaged easily. Car batteries have a technical index to indicate the battery’s anti-vibration performance! If the battery that meets the standard vibrates frequently in a poor working environment, it will certainly be damaged.
