Tesla announced Model 3 battery details, claiming that its energy density is the highest in the market. According to foreign media reports, Tesla claimed that its vehicle battery's energy density ranks in the forefront of all similar products on the market, and that the battery's cobalt metal The amount is also relatively small. Tesla designed the battery architecture for the Model 3 model, which uses a larger 2170 battery and also cooperated with Panasonic to manufacture the battery at Tesla’s Nevada Super Plant No. 1.
The details of the Tesla Model 3 battery were mentioned in Tesla's email to shareholders in the following days:
“The energy density of the cells used in the Tesla Model 3 is at the top of all models. The company significantly reduced the cobalt content while increasing the nickel content, maintaining excellent thermal stability, and thus increasing the energy density. Nickel Cobalt Aluminum (Nickel -Cobalt-Aluminum) The chemical ratio of the cathode of the battery has been lower than that of other battery manufacturers. The ratio of nickel-magnesium-cobalt (nickel-manganese-cobalt) used in the battery cathode of the latter is 8:1:1. For this reason, even with the battery, the Model 3's gross weight is comparable to gasoline."
Although Tesla has repeatedly emphasized that its energy density ranks first in the industry, from the perspective of the laws of physics, it still seems to be debatable. Many Tesla Model 3 owners tested batteries and claimed that their energy density was 5,750 to 6,000 mAh, but this value has not yet been demonstrated.
Tesla lowered the cobalt content in the battery cathode, perhaps because the price of cobalt metal more than doubled in the past year. Since all kinds of battery chemicals are inseparable from cobalt, the demand for cobalt also shows a substantial growth trend, and batteries and energy storage systems are bound to use cobalt metal.
According to a report, the cost of electric vehicle batteries fell to $227/kWh last year, and Tesla claimed at the time that its battery cost was less than $190/kWh. According to industry estimates, Tesla's Tesla Semi's pricing will only be beneficial if Tesla's battery cost price falls below $100/kWh, and Tesla Model3 will be profitable.
Absolute rotary Encoder measure actual position by generating unique digital codes or bits (instead of pulses) that represent the encoder`s actual position. Single turn absolute encoders output codes that are repeated every full revolution and do not output data to indicate how many revolutions have been made. Multi-turn absolute encoders output a unique code for each shaft position through every rotation, up to 4096 revolutions. Unlike incremental encoders, absolute encoders will retain correct position even if power fails without homing at startup.
