TeLink digital control system for vehicle function extension

One of Autostrada’s key products, TeLink, is a digital control system that can be integrated seamlessly into a vehicle’s CAN operating system. Additional functionality, safety, monitoring and control functions included.

TeLink systems are used in a wide range of utility vehicles and basic supply vehicles, where efficiency and reliability are critically important.

MPR20 for the dual battery operating system

Part of Autostrada TeLink is the provision of a dual battery operating system. It supplies auxiliary power for all the vehicle’s auxiliary and safety equipment such as motor and speed control, emergency start, communication systems, signal lamps, driving lights or working lights.

The TeLink system uses E-T-A’s MPR20 power relays integrated into the battery management and emergency control system. The MPR20 isolates the auxiliary battery from the main battery in the battery management system during normal operation and connects the auxiliary battery to the vehicle charging system via the TeLink control.

In addition, E-T-A’s power relays are used to provide an “Emergency Battery Linking” function that allows the vehicle operator to overrule the auxiliary battery disconnection rules and connect the batteries. This provides additional starting power to start a vehicle when the main battery is discharged below the threshold value required to start the vehicle.
