DCAR-E 3W Device
Our custom telematics device designed to monitor and optimize electric rickshaw fleets. With this onboard technology, you get high-performance fleet management tailored to your business requirements.
Why Choose the DCar-E 3W?
Instantly view the position and activity of your vehicles for more responsive day-to-day management. This real-time tracking helps optimize the overall utilization of each electric vehicle.
The system blocks the vehicle from starting unless a valid booking is active in the app. This prevents unauthorized use, theft, and unplanned departures, while strengthening security and meeting your insurance requirements.
The device automatically reports key data: mileage, trips, vehicle status, critical levels, battery range, and technical events. Vehicle health analysis, preventive maintenance, and usage tracking become simple, reliable services, with no manual data entry required.

Frequently Asked Questions
A telematics device for electric fleets is an embedded telematics unit that connects directly to the vehicle bus (via the CAN network). It collects and transmits, in real time, key information about the activity and status of light electric vehicles (such as rickshaws or 3-wheelers). With technologies such as LTE Cat-M1 (4G) connectivity and an integrated GPS (GNSS) module, this system reports data to a SaaS management platform to enable comprehensive fleet tracking.
Installing our devices offers many benefits for the company and for fleet managers:
- Optimize vehicle use and routes in real time.
- Reduce operating costs and save energy with the eco-driving module.
- Anticipate maintenance through mechanical alerts and engine fault codes.
Strengthen the safety of drivers and equipment with a remote immobilizer system.
While fuel consumption indicators are the norm for combustion engines, our solution adapts perfectly to the energy transition. The device includes an ADC sensor for monitoring the electric vehicle’s battery voltage. This precise analysis makes it possible to monitor the remaining range, plan each charge efficiently, and avoid running out of power, ensuring maximum availability of your fleet.
Yes, perfectly. Our technology includes a high-sensitivity GNSS module with integrated antennas, supporting multiple navigation systems. For data transmission, the device uses the LTE Cat-M1 network with 2G fallback. This ensures robust telematics connectivity and reliable GPS tracking for your cars and rickshaws, even in constrained environments or isolated geographical areas (such as our large-scale deployments in Africa).
Security is at the heart of our telematics solution. The device includes a smart immobilizer feature: the vehicle cannot start if no valid booking is detected in the app. In addition, the integrated sensors can detect risky driving behavior (speeding, harsh braking) and protect the company in terms of insurance.
Absolutely. The architecture of our telematics device for electric fleets is designed to be compatible with existing fleet management platforms. It uses standard data transfer protocols and offers full Over-The-Air (OTA) capability. This enables fully customizable, smooth integration with all SaaS solutions and monitoring tools on the market already used by your company.
Designed for large-scale deployments, this device features plug & play technology. Its hardware installation takes less than 30 minutes per vehicle, which minimizes the downtime of your micro-mobility fleet. In addition, our after-sales service is based in France, ensuring responsive technical support for the analysis of your day-to-day usage.
