Increase utilization and protect revenue with real-time vehicle data
TELL Connect Car provides real-time, factory-installed vehicle data for car rental fleets without installation. This allows for more accurate monitoring of mileage accounting, fuel reimbursement, and vehicle technical condition.
THE BIGGEST BUSINESS RISKS FOR CAR RENTAL COMPANIES
When data is delayed, the loss has already occurred
The car is the most important revenue-generating asset for a car rental business. The more it rents, the higher the profit. However, this requires accurate and timely information about the use and technical condition of the vehicles.
Without visibility into mileage, fuel levels, dashboard error messages or the current status of the vehicle, revenue can easily be lost. Inaccurate mileage billing, fuel disputes, late-detected technical faults or late returns all reduce fleet utilization.
TELL Connect Car closes this information gap – without installation, with data coming directly from the vehicle's factory on-board system.
The car rental business model is based on fast fleet turnover, accurate billing, and the continuous availability of cars.
The biggest problems usually arise from the car rental company not being able to see the usage and condition of the vehicles in a timely manner.

the vehicle does not return with the same amount of fuel as it was taken away with

Exceeding the mileage limit will only be revealed upon return.

the vehicle does not return to the specified location on time

the renter ignores the dashboard error messages

the vehicle is taken abroad, even though the contract prohibits this

A hidden technical fault causes the car to be out of service for days
This is coupled with the administrative burden of manual status checks, Excel-based records, and customer reconciliation, which slows down fleet operations.
In the case of electric and hybrid vehicles, additional questions arise: battery charge, charging cycles and range directly affect whether the car can be immediately released to the next renter.
THE SOLUTION
Telematics system supporting operations for car rental companies
TELL Connect Car is an operational support telematics system that takes the necessary information directly from the vehicle's factory data platform.
Advantages of the system:

no device installation

no installation logistics

no warranty risk

no operational problems due to hardware failure
The system provides real-time information, including:

About mileage

About fuel level

About vehicle use

About technical error messages

About the charging capacity of electric cars
This way, the car rental company can more accurately control mileage-limited contracts, fuel billing, and respond to technical problems with vehicles in a timely manner.
The system is not intended to monitor the tenant, but rather to provide transparency into the operational status of the vehicles , which directly supports revenue optimization.

BRAND-RELATED DATA ACCESS AND PROCESSING
Manufacturer data structures
TELL Connect Car works from the vehicle's factory data platform, but the range of data available may vary by manufacturer and model. Some brands provide detailed diagnostic data, while others make more limited information available.
The data that can be processed – such as mileage, error codes, service interval or battery status – depends on the specific make and model.
Before the launch, we will discuss which dataset supports the vehicle brands in your fleet and which functions are available from it.
Detailed data sets and feature lists are also available for each brand on the website.
