EV Charging Terminal and Energy Monitoring Solution
Successful charging operations depend on stable human-machine interaction, reliable billing control and sustainable ad revenue. Built on the RK3576/RK3588, this solution integrates touch operation, billing control linkage, advertising playback and status monitoring in one terminal, compatible with mainstream charging operation protocols and supporting remote O&M and OTA. Hongyin Tech covers the full delivery from requirements review to volume production. Submit your requirements for a free review and selection advice within 48 hours.
Pain Points
- Outdoor 24/7 deployment with heat and surge exposure pushes consumer-grade boards to high failure rates
- Ad screens sit idle or lack playback capability, leaving advertising revenue untapped
- Integration with multiple charging operation platforms is labor-intensive, with frequent protocol updates extending cycles
- Piles are geographically dispersed; on-site maintenance is costly and remote diagnostics plus OTA are essential
- Billing and payment flows demand high stability and a SoC platform with long lifecycle supply
Recommended Hardware Configuration
| SoC platform | RK3576 (4x A72 + 4x A53) or RK3588 (4x A76 + 4x A55), chosen by UI and advertising workload |
|---|---|
| AI compute | 6TOPS NPU, available for audience analytics to boost ad value (per chipset datasheet) |
| Memory & storage | LPDDR4/4x + eMMC for ad content caching and local billing records |
| Display output | HDMI/LVDS/MIPI-DSI for 7-32 inch touchscreens and portrait ad displays |
| Network & I/O | Dual 4G/Ethernet, RS485/CAN to charging control unit, GPIO for emergency stop and indicators |
| Power & enclosure | Wide-temperature, wide-voltage design with vehicle/pile power input on an industrial-grade SoM |
Software Capabilities
- HMI: Android or Linux options with full-flow UI covering scan-to-charge, status and order queries
- Billing control: RS485/CAN communication with the charging control unit for start/stop and status feedback
- Protocol integration: adaptation to mainstream charging operation protocols, with order and reconciliation flows validated
- Ad operations: split-screen playback, remote content push and scheduling by site or time slot
- Remote O&M: device dashboard, remote logs, OTA updates and fault alerts to cut site visits
Deliverables & Services
- Free requirements review: screen specs, platform integration list and OS selection, with advice within 48 hours
- Hardware design: SoM plus carrier design, display matching and power/protection circuits for pile environments
- BSP/drivers: OS tailoring, touch and display drivers, 4G/CAN and peripheral driver development
- Pilot integration: end-to-end validation with the charging control unit, operation platform and payment flow
- Volume support: low-volume ordering, certification assistance and long-term lifecycle supply
FAQ
Q：How do I choose between RK3576 and RK3588 for a charging pile?
If the focus is touch interaction, billing linkage and standard ad playback, the RK3576 is more cost-effective. For large portrait ad screens, multi-video playback or future AI features such as audience analytics, we recommend the RK3588. Submit your requirements and we will provide a clear recommendation within 48 hours after the free review.
Q：We already integrate with one operation platform. Can we keep it?
Yes. The solution supports mainstream charging operation protocols, and platform integration is routine commissioning work. We recommend sharing the target platform's integration documentation during requirements review so we can scope the effort and include it in the delivery plan.
Q：How is the hardware adapted for outdoor charging environments?
We use an industrial-grade SoM with wide-temperature, wide-voltage design, surge and reverse-polarity protection on the power side, and thermal structures customized to the pile installation. Screen brightness and ingress protection are confirmed during review based on placement (indoor garage or open-air site), subject to the chipset datasheet and design documentation.
Q：Will advertising playback interfere with charging operation?
No. Ad playback and the charging UI are resource-isolated: ads automatically switch to the operation screen when charging starts and resume afterward, while billing data is stored locally on a separate upload channel. On the RK3588, multi-core processing keeps video decoding and business logic apart to maintain smooth interaction.
