4G Intelligent Central Controller for Electric Vehicles
A single onboard module that unifies GPS, 4G LTE connectivity, CAN bus communication, UART display protocol, and cloud telemetry into one plug-and-play unit. Designed for OEM integration and rental fleet operators — enabling remote monitoring, anti-theft control, and OTA updates fleet-wide.
What the 4G Smart Controller Delivers
4G LTE Connectivity
Continuous two-way data link with automatic NB-IoT fallback in low-signal zones
GPS + AGPS Tracking
±5m accuracy, cold start under 30s, real-time fleet map with route playback
CAN Bus Integration
Native CAN 2.0 / RS485 reads BMS cell voltages, SOC, SOH, fault codes directly
Dashboard Protocol
Built-in UART display driver — no external adapter needed for instrument clusters
Remote Lock / Unlock
Cloud-triggered BMS & motor relay lock in under 3s — anti-theft & lease enforcement
OTA Firmware Updates
Push BMS & gateway firmware to entire fleet over 4G — with automatic rollback
Geo-Fencing Alerts
Define up to 50 virtual zones; instant push notification on boundary crossing
Fleet Analytics
SOC/SOH trends, usage heatmaps, cycle counts, and predictive maintenance alerts
ERP / API Integration
REST API + Webhook — connects to any fleet management ERP or CRM system
