Product Features

Built-in 4G communication and positioning antenna, easy to install;

Low power consumption: turn off the fire and sleep into a low power consumption state, and the sleep current is less than 0.1mA

The backup battery can be used for more than 15 days (upload a location information every day);

Support 1-way CAN communication;

Chip SIM card;

Built-in encryption chip;

Support timing wake-up, ACC wake-up, CAN wake-up;

Supports simultaneous connection to 4 monitoring centers;

Protection grade IP67.

Supports 1-channel CAN data collection, complies with CAN2.0 specification, and can be connected to CAN bus protocol.

Supports SAEJ1939, ISO27145 and ISO15765 diagnostic protocols. The terminal sends a request to the vehicle bus, obtains the corresponding data and uploads it to the platform.

Support ACC wake-up and CAN communication wake-up. When ACC starts, the terminal wakes up from sleep state. When the vehicle CAN starts communicating, the terminal can be woken up.

After the ACC is turned off, the terminal can be programmed to automatically power off and the terminal stops working, achieving low power consumption with power consumption ≤0.1mA.

The power input range is 9-36V; the limited voltage is 60V, and the anti-reverse voltage of the power supply is 60V.

1 switch signal input, 1 vehicle speed sensor signal input.

The terminal supports connecting to 4 monitoring centers at the same time and can obtain information issued by the monitoring center.

Supports remote "cloud" guardian functions such as remote fault diagnosis and debugging, remote automatic program maintenance, remote parameter configuration, terminal operation statistics, etc.

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.
