Built-in encryption chip, support encryption algorithm

Comply with vehicle manufacturers’ EMC and EMI requirements;

Meets EU CE remote emission management vehicle terminal technical requirements.

Supports 2-channel high-speed CAN data acquisition, compliant with CAN 2.0 specifications, with a speed of up to 500K/S. Can interface with the vehicle manufacturer's CAN bus protocol.

Can collect engine data stream information required for vehicle emissions such as vehicle speed, atmospheric pressure, NOx, SCR temperature, etc. For new energy electric vehicles, it can collect vehicle battery, motor, and other status data and upload it to the platform.

Supports SAE J1939, ISO 27145, ISO 15765 diagnostic protocols. The terminal sends requests to the vehicle bus to obtain corresponding data and uploads it to the platform.

Supports ACC wake-up and CAN communication wake-up. The terminal is awakened from sleep mode when ACC is ignited. The terminal can be awakened when the whole vehicle CAN starts communication.

After ACC is turned off, the terminal can be programmatically powered off, stops working, achieves low power consumption, and power consumption is ≤2mA.

Supports remote automatic program maintenance and remote parameter configuration.

Wide voltage input protection: Power supply input range is 9-36V, maximum voltage is 60V, power reverse connection protection voltage is 60V.

Dual-center: The terminal supports simultaneous connection to two monitoring centers and can receive information sent by the monitoring centers.

Frequently Asked Questions

What is T-BOX?

Telematics BOX, also known as Telematics Control Unit (TCU), integrates functional modules such as GPS, external communication interface, electronic processing unit, microcontroller, mobile communication unit and memory. T-BOX is connected to the vehicle CAN bus internally; externally, it realizes information interaction between vehicle terminals, handheld devices, roadside units (RSU) and public networks using V2V, V2R, V2H, and V2S communications through the cloud platform.

How much does a telematics control unit （T-box） cost?

Telematics Control Unit(T-box) can be equipped with different hardware configurations according to customer requirements to achieve special functions. We will quote based on customer requirements!

*The cost of Yuwei products with the same functions is 20% lower than that of foreign manufacturers.

Email consultation fees will not waste your time, but will only save you more costs.

What are the general functions of TBOX?

The functions provided by TBOX include network access, OTA, remote control, location query/vehicle tracking, battery management, location reminder, eCall, remote diagnosis, platform monitoring/national supervision, etc.

What are the main functions of the electric vehicle tbox?

1. Collect and store driving data and trajectory records, analyze these data, and then display them on the display.

2. Use the tbox system to remotely query and control the car, such as controlling the car to open the door, honk, flash the lights, turn on the air conditioner, start the engine, etc. You can also check the car's position.

3. Other functions: such as road rescue, fault diagnosis, and abnormal reminder. After an accident, the tbox system will automatically dial a rescue call to allow users to receive timely rescue. When a malfunction occurs, timely feedback will be provided; if an abnormality occurs, such as being towed away, burglary, etc., an alarm will be issued.
