Samsung SDI is the main battery business subsidiary of Samsung Group. Last year, 70% of the batteries of the first Galaxy Note7 mobile phones shipped were supplied by SDI, which was initially suspected to be the culprit of the Note7 explosion, but the final result shows that it is not SDI's problem, and Samsung has its own way (inexplicably carrying the pot) Of course, as a battery company, SDI is also vigorously developing automotive batteries in addition to the batteries required by mobile devices. This time SDI announced their latest achievements at the North American Auto Show.

SDI's new generation of fast charging battery for vehicles reduces the weight by 10% compared with the existing products, and can be fully charged by 80% in 20 minutes, with a range of 500 kilometers; The battery reduces the components and weight by 10%. The design goal is to ensure that the electric vehicle can travel 600 kilometers after 20 minutes of charging. The modular design is also used. The ordinary EV battery module contains 12 battery cells with a capacity between 2-3 kWh, while the integrated battery module will contain 24 battery cells with a capacity of 6-8 kWh, But the official said that mass production would not start until 2021.
