What Is the Multi-Robot AMR Charging Hub?

The BRIDZA Multi-Robot AMR Charging Hub is a centralized energy distribution system purpose-built for warehouses and manufacturing facilities running 50 to 200+ autonomous mobile robots. Instead of deploying individual chargers one-by-one—which quickly overwhelms facility electrical panels and creates unmanaged power demand—the hub connects to a single 600A three-phase input and intelligently routes power to hundreds of charging endpoints on demand, ensuring every robot in the fleet receives optimal charging without exceeding the building's electrical service capacity.

Centralized Power Entry

One electrical connection replaces dozens of individual charger circuits. The Power Distribution Unit (PDU) accepts 380–480V AC three-phase input and steps it down to regulated DC charging rails, serving up to 200 endpoints from a single infrastructure point.

Intelligent Power Routing

The hub's embedded controller continuously monitors each robot's battery state-of-charge, task schedule, and thermal status. Power is dynamically allocated based on priority—robots heading into idle periods charge first, while active robots defer, keeping total facility draw within contract limits at all times.

Modular Scaling

Start with 50 endpoints and expand to 200+ by adding hot-swappable power modules—no rewiring, no panel upgrades. The modular architecture grows with your fleet, so capital expenditure matches actual robot deployment rather than speculative over-provisioning.

Core Features & Capabilities

Every feature is designed to maximize robot uptime, protect facility electrical infrastructure, and simplify multi-brand fleet management.

① Intelligent Charging Scheduling

Priority-weighted round-robin algorithm combined with predictive scheduling. The system ingests task queues from WMS and fleet management software, anticipating which robots will become available for charging and pre-allocating power slots. Robots returning from high-priority tasks receive immediate charging priority, while scheduled-break robots fill off-peak windows.

② Multi-Brand Protocol Compatibility

Native CAN bus, Modbus TCP, MQTT, and REST API interfaces enable a single hub to manage heterogeneous robot fleets—KUKA, MiR, Geek+, OTTO by Rockwell, Locus, Fetch, and others—simultaneously. The protocol gateway translates between different battery management systems (BMS), handling 24V, 36V, and 48V battery platforms without vendor-specific chargers.

③ Dynamic Load Balancing

Real-time current sensing at each endpoint feeds a closed-loop control algorithm that redistributes power within 100ms. When total facility draw approaches the contracted demand threshold, the system proportionally throttles charging currents across all active endpoints—never fully cutting off any robot—maintaining 40%+ peak demand reduction without fleet downtime.

④ Battery Thermal Management

Per-cell temperature monitoring during charging detects anomalies before they escalate. The hub implements CC-CV (constant current / constant voltage) charging profiles optimized for LiFePO4, NMC, and LTO battery chemistries. In cold environments (down to -20°C), pre-charge warming cycles activate automatically to protect battery health and ensure consistent charge acceptance.

⑤ Fleet Energy Dashboard

Web-based real-time dashboard displays per-robot state-of-charge, charging power allocation, energy consumption trends, and battery health indicators across the entire fleet. Configurable alerts notify operators of communication losses, thermal anomalies, or approaching demand threshold breaches. Data logging retains 2+ years of operational history for trend analysis.

⑥ Hot-Swappable Endpoint Modules

Each charging endpoint module is field-replaceable without powering down the hub. Failed modules can be swapped in under 5 minutes, maintaining continuous operation for all remaining robots. This design eliminates single-point-of-failure risk and reduces mean-time-to-repair from hours to minutes.

⑦ Contactless & Physical Connector Options

Support for both inductive (wireless) charging pads and physical contact charging pins, configurable per endpoint. Wireless endpoints suit clean-room and food-grade environments where contact contamination is unacceptable. Physical pin connectors deliver higher power (up to 6kW per endpoint) for heavy-duty applications.

⑧ Arc Flash & Fire Safety Systems

Integrated arc detection sensors trigger shutdown within 5ms of fault conditions. Optional smoke and electrolyte vapor detectors connect to the hub's safety controller for early fire warning. Certified to CE, UL 508A, and IEC 62443 industrial cybersecurity standards for comprehensive operational protection.

System Architecture & Integration

The charging hub is designed for drop-in integration into existing warehouse automation ecosystems, connecting to fleet management systems, WMS platforms, and building energy management infrastructure.

FMS / Fleet Controller Interface

The hub exposes a standardized fleet management system interface via VDA 5050, OPC-UA, or REST API. The FMS sends robot availability windows and battery status; the hub returns charging slot assignments and estimated completion times. This bidirectional communication enables seamless charge-while-idle scheduling without modifying existing robot task logic.

WMS Integration for Demand Forecasting

By connecting to the warehouse management system via JSON/HTTPS connectors, the hub anticipates charging demand based on order waves, picking schedules, and shift changes. Pre-shift robots receive priority charging; during order surges, the hub defers non-critical charging to maintain fleet availability. No custom development is required for major WMS platforms.

Deployment Configurations

Single-hub central: One PDU serves all endpoints in a star topology—ideal for facilities under 200 robots. Multi-hub distributed: Multiple PDUs across facility zones connected via Ethernet backbone—scales to 400+ robots across large sites. Retrofit overlay: Hub endpoints install alongside existing individual chargers during transition periods, managed through the same dashboard.

Building Management System (BMS) Connection

Modbus TCP and BACnet gateway options enable the charging hub to communicate with building energy management systems. Facility managers can set absolute power caps, time-of-use rate schedules, and renewable energy priority rules—ensuring the charging infrastructure operates within the site's overall energy strategy.

Application Scenarios

E-commerce & 3PL Fulfillment

100–500 AMRs for goods-to-person picking face concentrated charging demand during peak seasons. Dynamic power distribution maintains 98% fleet uptime during order surges. Modular endpoint expansion matches seasonal scaling.

Automotive Manufacturing

Multi-brand AMR fleets delivering parts to assembly lines need synchronized charging between production cycles. Predictive scheduling aligns with takt time. VDA 5050 integration enables direct automotive-grade fleet controller communication.

Cold Storage & Pharma Logistics

IP65 cold-rated endpoints and LiFePO4-optimized CC-CV profiles operate reliably down to -20°C. Automatic pre-charge warming cycles and per-cell thermal monitoring protect batteries in freezing environments.

Airport Cargo & Semiconductor FABs

Contactless inductive charging pads suit contamination-sensitive environments (clean-rooms, food-grade zones). IP65 remote endpoints withstand outdoor ramp conditions. Load balancing ensures continuous availability during 24/7 operations.

Designed for the Electrical Infrastructure Reality

The charging hub solves three infrastructure constraints that limit AMR fleet scaling beyond 100 units.

Electrical Panel Constraints

Most warehouse panels support 400–800A total. The hub's load balancing algorithm ensures total charging draw stays within this limit—enabling 200+ robot charging without panel upgrades.

Multi-Brand Unification

A single hub replaces brand-specific chargers with universal protocol support. One infrastructure investment serves the entire heterogeneous fleet regardless of robot manufacturer.

Scalable Without Rewiring

Modular endpoint expansion adds charging capacity without new electrical circuits. Fleet growth from 50 to 200 robots requires zero additional facility electrical modifications.
