The application of flexible circuit board FPC in automotive electronic power batteries, the recent work responsibilities are mainly on some things that can be done, Boss asked me to go deeper and do some special discussion on the various aspects of the battery. I am still talking about the development and changes in the horizontal automotive electronics field, and the vertical application in a single field. The sampling harness is divided into several stages 1) The battery module initially extends the pole measurement point to the connector through the wire, and then the connector is connected to the LECU. The sampling harness has a long length, a large number of connection points, and no overcurrent fuse mechanism is designed. There is a significant problem here, if the connector is not carefully considered, the harness short circuit will cause several different failure modes. a) Short circuit between different voltages b) short circuit inside the ASIC chip c) connector condensation and water intake 2) The sampling line uses a circuit board instead of part of the sampling line 3) FPC circuit board, one can use different process materials to connect the sampling points, one can design the line fuse, and can also leave the position of the temperature sensor NTC. From a general point of view, the use of FPC can reduce the complexity of the Module integration process, reduce weight and save costs, so FPC technology uses more mainstream solutions. Yazaki has also been applied to the existing electrified vehicles in Japan. In other areas, FPC is also used a bit more, and the traditional copper wire connection has changed. Instrumentation system Lighting system and mobile phone camera Summary: Regarding FPC material, cable width calculation, and fuse protection current design, we can convert and test optimization according to the previous PCB design specifications, the direction is this direction. Hardware and process engineers are constantly optimizing their original designs with new materials and designs. Guangzhou Bolei Electronic Technology Co., Ltd. , https://www.nzpal.com
