How many batteries does Tesla 75d have and how many batteries does 100d have?

The above is the information I collected about Tesla piecemeal. The information about batteries is as follows, which can answer your questions. The top 85kW Model S used nearly 7000 Panasonic NCR 18650 3 100mah batteries, which were grouped twice and connected in series and parallel. Sensors are set to sense the working state and temperature of each battery, which is controlled by the battery control system. Prevent overheating, short circuit, temperature difference and other dangerous situations. In daily use, ensure the safety of the battery under high current charge and discharge. Other manufacturers use large batteries, only a few hundred at most, and there is no control system accurate to each battery. Tesla chose Panasonic's 18650 battery for the following four reasons: 1) higher energy density, better stability and consistency; 2) the cost of the battery system can be effectively reduced; 3) Billions of 18650 batteries are produced worldwide every year, and the safety level is constantly improving; 4) Small in size but high in controllability, even if a unit of the battery pack fails, the impact caused by the failure can be reduced. Requirements for batteries: stable performance, high safety factor, and many times of cyclic charging. Lithium iron phosphate batteries are the first choice of power batteries in the market at present, such as Chevrolet Volt, Nissan Leaf, BYD E6, Fisk Karma and so on. Tesla's solution is to connect 683 1 Panasonic 18650 battery in series and in parallel with 2 ampere-hours. 69 cells 18650 cells are packed in parallel to form battery bricks; 99 battery bricks are connected in series to form a battery piece; 1 1 batteries form a battery pack, with a total of 683 1 batteries. Fuses are installed at both ends of each battery cell, each battery brick and each battery piece. Once the battery is overheated or the current is too large, it will immediately melt and disconnect the output. Only one fuse is not enough. On each battery, there is a BMB (Battery Monitoring Board) for monitoring the voltage and temperature of each battery block and the output voltage of the whole battery. On the whole battery pack, BSM(Battery System Monitor) is set to monitor the working environment of the whole battery pack. Include the current, voltage, temperature, humidity, orientation, smoke and the like of the battery pack. At the vehicle level, VSM (Vehicle System Monitor) is set to monitor BSM. This battery control system has become the technical core of Tesla, and I hope it can help you.
