What type of Tesla battery is this?

Tesla batteries use 18650 batteries produced by Panasonic, but after Model 3 officially goes into production, the new 21700 batteries will replace the 18650 batteries and become the new battery cells. The energy density of its 21700 battery system is about 300 Wh/kg, about 20% higher than the 250 Wh/kg of the original 18650 battery system. In the battery

What type of Tesla battery is

Tesla batteries use 18650 batteries produced by Panasonic, but after the Model 3 officially goes into production, the new 21700 batteries will replace the 18650 batteries, becomes a new battery core. The energy density of its 21700 battery system is about 300 Wh/kg, about 20% higher than the 250 Wh/kg of the original 18650 battery system.

Tesla stands out from other new energy vehicle companies in terms of batteries. For example, beats themteries lithium-ion, lithium-manganese batteries and ternary lithium batteries used by BYD, Nissan and BAIC are different. Judging from the disassembled Tesla batteries, most Tesla models are Panasonic 18650 cylindrical lithium batteries. 1650 lithium batteries are generally packaged in steel cases. In order to prevent the steel case from exploding due to a sudden increase in pressure due to charging, the top of the battery will be equipped with a safety valve, and some batteries will also be equipped with a plate protection to prevent overloads and short circuits. 1. Tesla's first Roadster used Panasonic's NCR18650A battery with a nominal voltage of 3.6 V and a capacity of 3.1 Ah. The previous 85 kWh battery used an NCR18650B battery with a nominal voltage of 3.6 V and a capacity of 3.1 Ah. The new 21700 battery used by Tesla is a batteryternary lithium and the cathode material is lithium-nickel-cobalt aluminate (NCA). This cylindrical ternary battery currently constitutes the highest energy density power battery solution. Compared to prismatic batteries, these batteries have higher energy density but lower stability, so they require better BMS (battery management system) support. 3. Under existing conditions, the energy density of its 21700 battery system is about 300 Wh/kg, which is about 20% higher than the 250 Wh/kg of its original 18650 battery system. At the same time, according to Panasonic power lithium battery cell test data, the volumetric energy density of its 21,700 battery cells is much higher than that of its 18,650 battery cells. The increase in energy density of individual cells is much greater than the 20% after regroup.

What is the capacity of Tesla's battery?

The Model S battery is made up of 7104 18650 lithium batteries, with a capacity of 15 to 60 kWh. It consists of 16 battery packs connected in series, each battery pack consists of Each 74-cell battery is composed of 444 lithium-ion batteries connected in parallel. The battery is protected by a shell to prevent shock.

Tesla uses 18650 batteries produced by Panasonic. Once Model 3 is officially put into production, the new 21700 battery will replace the 18650 battery as the new battery. The 2700 battery is a ternary lithium battery, and the positive electrode material is lithium-nickel-cobalt aluminate (NCA). This cylindrical ternary battery currently constitutes the highest energy density power battery solution. Compared to prismatic batteries, these batteries have a lower energy densityhigher ic but lower stability, so they require better BMS (battery management system) support. Under existing conditions, the energy density of its 21700 battery system is about 300 Wh/kg, which is about 20% higher than the 250 Wh/kg of its original 18650 battery system. At the same time, according to Panasonic power lithium battery cell test data, the volumetric energy density of its 21,700 battery cells is much higher than that of its 18,650 battery cells. The increase in energy density of individual cells is much higher than 20% after clustering. The Tesla panel's 16 battery packs are evenly distributed across the case, making the overall structure compact. Ceramic tiles help dissipate heat. Each battery pack is made up of six unique battery packs connected in series, but the arrangement of the batteriescs of single batteries is not balanced, but irregular. It is assumed that this is intended to facilitate the arrangement of the heat pipes in the battery pack. The voltage of the whole panel is 313.8V, and the voltage of a single battery is 196.3V. Obviously, this battery has not reached the rated output voltage, which may be due to insufficient battery power.

What is the difference between Panasonic 18650 lithium battery 3.7 and 4.2?

Slightly lower energy density.

It’s precious. The current market price is around 1,200 yuan per kilowatt hour. Currently, the 18650 lithium battery with the same quantity is the most expensive Panasonic lithium battery in Japan. about 30-40 yuan per battery, but the energy density is higher, which is currently the industry ceiling. The best domestic is the CATL, which coIt costs about fifteen to twenty yuan per section.

Lithium batteries are only 3.7V (3.6 at first and 3.8V now), which is the rated voltage. 4.2V is the charging termination voltage of lithium battery, which can be understood as the highest voltage.

The same lithium battery has different voltages at different power levels. Approximately between 3.0 and 4.2 V, 3.0 V is the end of discharge voltage and 4.2 V is the end of charge voltage.
