Blue Tooth Integration for Electric Vehicles

The new generations of vehicles might have an unspecified variety of microcontrollers connected through a few networks. An advantage of this is the vehicle can be independently customized by applications. Another advantage is that the vehicle, to a great extent, may have self-analytical functionality. To fully utilize such features, it is essential to have a bidirectional communication between your vehicle system, manufacturing tools and to service tools such as EV charging stations. In addition to processes for downloading new applications, the filtering and sorting parameters of diagnostic needs should be fully synced, as should status messages.

In standard service devices, the association between the automobile system and the service instrument is made via a cable, usually straight into the CAN bus through a gateway such as a modem or WIFI. Availability of products like on https://emotorwerks.com/tesla-charging-stations solves integration issues between the vehicle and the charging station. The implementation of wireless technology such as Bluetooth then streamlines the communication between the vehicle system and the service instrument.

A good example of this is Tesla’s EV charging stations. The service instrument (Charging Station) employs wireless inductive charging technology to eliminate the need to plug in your vehicle. So how then, is the power delivered to your vehicle? The magic happens through a principle called resonant inductive coupling. In this instance, two coils deliver the power, wirelessly, in the space separating the wireless charging station and the vehicle.

When we compare the two communication modes, Universal Serial Bus and Bluetooth, we find the mobility and flexibility have really been transformed by integrating Bluetooth technology. In the vehicle manufacturing process, a lot of applications are downloaded as the last step in the manufacturing line. This is an application where Bluetooth will be ideally suited. The Bluetooth base station is attached to the manufacturing field bus. When the vehicle is attached to the Bluetooth base station, it syncs using the serial number. The manufacturing computer then syncs the software for the vehicle through the field bus into the base station, which then transmits it to the vehicle. That’s a dedicated user that requires no additional Bluetooth unit (than those installed in the vehicles) would be needed.

So, what would be the other scenario for using Bluetooth? A good example would be when the vehicle enters the station service, its Bluetooth channel gets in contact with the support stations main computer. This has previously exchanged info with the vehicle computer via the mobile phone system. The support station main computer alerts the operator who assigned the task and his Personal Computer establishes contact with the vehicle and downloads any info needed. The serviceman gets any work directions needed on his PC. When servicing the vehicle, he can control and adjust, various functions via the personal computer.

Any wireless transmission to the CAN bus should be conducted with a high-performance Bluetooth unit and should be standard in all vehicles. To achieve this goal requires a cost-effective, high-performance Bluetooth unit that may be used for any application. In addition, any installation or upgrade should be seamless and automatically integrate with existing systems. Using wireless communication between the vehicle and service instruments and applications will streamline service and raise the overall standard of service and therefore, vehicle performance.
