Tesla battery life attenuation and life analysis

Tesla battery life decay and life analysis No matter what the future of Tesla, it is now having a huge impact on the global automotive industry. This article is about Tesla's battery system and battery life of pure electric vehicles. Since the content of the contact is a bit vivid, try to write some simple and simple here, and welcome follow-up engineers to communicate with me. The top of the Tesla battery system Tesla’s battery system is strictly two generations, the sports car is the first generation, and the ModelS is the second generation. S-type mid- and early-stage planning is 40kwh (cancelled), 60kwh (cancelled), 70kwh, 85kwh, 90kwh, of which the two more recognized standards are: 85kwh (7104 pieces of 74P×6×16) 400V60/40kWh (5376 pieces of 64P×6 ×14)kWh Here the battery system is broken down into: Battery module: The battery module is an important subunit of the battery system and is the core of Tesla's plan. Structural system: The battery system uses a large number of barrier structures to achieve the effects of waterproof and heat insulation. Heat treatment system: including cooling system. Harness system: It consists of two parts: high-voltage bus and low-voltage communication wiring harness. Electrical and electronic systems: including battery handling, relays, charging resistors, etc. Exhaust system: The first is to release the pressure of the battery pack, the first is the two parts of the exhaust valve and the interface. At the same time, the most important thing is its battery module planning. The battery module is composed of the following parts: Battery unit: Panasonic battery. Current Motherboard: Used to connect the battery, connect the positive and negative electrodes of each battery together, there are 7 different standard boards in total. Isolation layer: The isolation layer isolates the battery from the cooling pipe and serves as insulation. Cooling copper pipe: through each side of the connection with the monomer, the heat is discharged from the entire battery module. Block board: on the top of the battery cover, play an insulating purpose. BMU collector: measure voltage and temperature. Fuse: Connect the battery cell with the busbar brand, and choose the bonding technology in the semiconductor, which is a very difficult technology for battery packaging. Temperature sensor: Collect the input and output temperature of the cooling pipe. Sampling voltage collection harness: Collect battery voltage and fix it with a special fixed line index structure.
