Smart Battery Chargers & AGV Charging
From marine shore power to the charging stations inside fully autonomous warehouse robots, Sudtech designs smart charging systems that adapt to the battery chemistry, the environment, and the application. A charger that cuts corners on multi-stage control or thermal protection will degrade battery life and create a field reliability problem. We engineer around that from the start.
Applications We Power
- AGV & AMR Autonomous Robots — high-power smart chargers (1000W–3000W) with CAN bus and RS-485 communication for fleet management integration
- Marine & Shore Power — IP68-rated chargers (up to 3kW) for sealed marine enclosures, wide-temperature operation
- RV & Mobile Power — 12V/100A chargers with multi-chemistry support, designed for continuous deployment in transport vehicles
- Industrial Battery Systems — 1500W–5kW AC/DC charging for Li-Ion, AGM and lead-acid banks in UPS, forklifts and energy storage
- Automotive Diagnostic & Service — 2000W/120A programmable chargers with remote control and logging
What the Charging System Needs
- Three-stage charging (bulk / absorption / float) with accurate termination for each chemistry
- CAN bus or RS-485 interface for AGV fleet management and remote monitoring
- IP67 / IP68 rating for outdoor, marine and wash-down environments
- Wide input range (85–264 VAC or 3-phase) for global deployment
- 100% rated output at 45°C ambient — chargers run hard in hot enclosures
- Bluetooth / Wi-Fi app control for IoT-connected systems
- CE, UL and IEC 62368 certification
How Sudtech Approaches It
Charging is not a commodity. The voltage regulation accuracy during absorption phase, the temperature compensation coefficients, and the communication protocol implementation all determine whether the battery reaches full capacity or degrades after 200 cycles. Our engineering team works from the battery specification and the application duty cycle — not a generic charger reference design.
For AGV and autonomous robot applications, we integrate the charging system with the robot’s fleet controller from the first design review. The charger is part of the system — docking alignment, handshake protocol, and charge state reporting are all in scope.
IoT-connected design example: Sudtech developed a robotic pool cleaner power supply with Bluetooth and Wi-Fi app control, 100% output at 45°C ambient, conformal coating, and IP68-ready construction — deployed at scale with a global marine robotics customer. Achieving all three at once — marine sealing, Bluetooth app integration, and continuous output at 45°C — required purpose-built enclosure and thermal engineering rather than off-the-shelf adaptation.
