Three Core Technical Upgrades

1. Charging Protocol Upgrade: BMS Autonomous Request + CAN Converter Coordinated Control

Three Typical Scenarios:

🎬 Scenario 🔋 Battery Request ⚖️ System Check ⚡ Final Execution 💡 Description
🟢 Sufficient Power Request 30A Has 30A Give 30A Meet demand, 2 hours full charge
🟡 Power Shortage Request 30A Only 20A Give 20A Reduced charging, 3 hours full charge
🔴 Battery Fault No request Detect abnormal Give 15A protection Auto protection, prevent accident

Core Advantages: ✅ Battery demand priority → ✅ System safety assurance → ✅ Intelligent fault tolerance

2. Charging Initiation Condition Upgrade: Dual-Condition Coordinated Determination

Core Improvement: Upgrade from "single condition" to "dual conditions simultaneously satisfied", preventing false starts.

Check Step Check Content Pass Condition Failure Result
① Battery Status Check BMS self-check battery status No over-temp/voltage/current/imbalance ❌ Reject Initiation
② Charging Application BMS send charging request Within 30s validity ❌ Application Timeout
③ Identity Verification CAN verify battery identity Identity legal and valid ❌ Reject Initiation
④ Permission Check IOT query slot permission Slot allowed to charge ❌ Reject Initiation
⑤ Power Check IOT check system power Sufficient power for new load ❌ Reject Initiation
⑥ Initiation Command CAN deliver start command Command transmission error-free ❌ Communication Failure
⑦ Charger Initiate Charger starts working Normal startup ❌ Device Fault
⑧ Current Confirmation Detect current within 10s Valid charging current exists ❌ Initiation Timeout

Dual Verification Mechanism:

Condition① Battery Application Condition② System Approval Final Result Description
✅ Has application (within 30s) ✅ Approve startup 🟢 Allow Charging Both conditions satisfied
❌ No application ✅ Approve startup 🔴 Reject Startup Battery no request, prohibit charging
✅ Has application ❌ Disapprove 🔴 Reject Startup System disapprove, prohibit charging
⏱️ Application timeout ✅ Approve startup 🔴 Reject Startup Application expired, re-apply

3. IoT Module Upgrade: New Intelligent Charging Strategy Management Function

Step IOT Function Life Analogy
① Real-time Monitoring Check power usage every second Check electric meter reading
② Intelligent Judgment Enough power for all batteries charging simultaneously? Can we turn on AC and oven together?
③ Power Allocation Enough→Start all / Not enough→Queue by priority Enough→Use freely / Not enough→Important first
④ Dynamic Adjustment Battery full→Release power to next Laundry done→Auto power to water heater

Four Typical Scenarios:

🎬 Scenario 🔌 Current Power Status 🤖 IOT Decision 💡 Analogy
🟢 Sufficient Power 50% idle remaining All batteries charge simultaneously Home off-peak hours, use freely
🟡 Power Shortage Only 10% space left Important first, others queue Peak hours, ensure fridge & AC first
🔄 Dynamic Scheduling Some battery full Auto allocate power to next Laundry done, next is water heating
👨‍💼 Manual Override Manually designate one Force charge designated battery Owner says: "Charge this one first"

Priority Rules: 🥇 Nearly full first (ready to use immediately) → 🥈 Important slots → 🥉 Normal batteries

Core Advantages: ✅ No power waste → ✅ No overload → ✅ Fully auto rotation charging - ✅ No Overload: Ensure total power not exceed limit

Safety Redundancy Design

  • Parameter Abnormality Protection: CAN converter, IoT module both possess parameter abnormality determination function, if detecting BMS request or CAN delivery parameters exceeding charger rated range (such as current>80A, voltage>84V), immediately prohibit initiation or stop charging, report fault and cut slot power

  • Communication Interruption Protection: If communication interruption occurs between CAN converter and BMS/IoT/charger (>5 seconds without receiving command or feedback), automatically stops charging, CAN delivers stop command, charger cuts output, IoT reports fault and clarifies interruption node

  • Power Overload Protection: IoT module real-time monitoring system total load, if strategy abnormality or component fault causing total load exceeding input power upper limit, immediately initiates overload protection, priority cutting non-priority slot power, if overload still unresolved then cuts total power, synchronously reports fault

  • BMS Fault Protection: If detecting BMS sending abnormal command, no command feedback, or battery status abnormal (over-temperature, over-voltage), CAN converter refuses to deliver initiation command, IoT module marks the slot as "abnormal slot", prohibits initiation charging, until fault investigation and device reset

Backend Management System

  • Remote Strategy Adjustment: Staff can remotely set IoT module charging strategy parameters through backend management system (power total capacity upper limit, battery priority, default parameters), strategy adjustments real-time synchronized to charging rack IoT module, no on-site operation required

  • Full Data Traceability: Backend system adds "BMS request data" "CAN delivery data" "charging strategy adjustment records" "power allocation records" data storage and query functions, storage cycle ≥90 days, facilitating tracing charging process, investigating faults, optimizing strategies

  • Remote Intervention and Fault Handling: Backend system real-time receives charging rack uploaded data and fault information, supports remote initiation/stopping chargers, adjusting power, simultaneously can send fault handling prompts to on-site display screen

  • Multi-device Coordinated Control: Backend system supports centralized control of multiple next-generation charging racks, unified strategy setting, monitoring all device status, statistics overall energy consumption, adapting to scaled charging scenario management

Core Advantages
  • Significantly Enhanced Intelligence Level: Charging parameters autonomously requested by BMS, fitting battery actual status, reducing battery consumption, extending battery lifespan; IoT module intelligently formulates charging strategy, realizing dynamic power allocation
  • Optimized Power Utilization: Dynamically adjusting charger initiation quantity and power based on input power total capacity, avoiding power waste, simultaneously preventing system overload, ensuring power supply safety and device stable operation
  • Substantially Improved Charging Safety: Dual-condition initiation determination, multiple safety redundancy mechanisms, preventing false starts, invalid initiations and various abnormal hazards, comprehensive safeguarding battery, device and personnel safety
  • Strong Compatibility and Expandability: Retaining original mature architecture, upgraded component high adaptability, reducing upgrade cost; reserved protocol and interface expansion space, can adapt to future new battery types and control demands
  • Enhanced Management Efficiency: Backend system and on-site display screen synchronized optimization, supporting remote strategy adjustment, fault investigation, data traceability, adapting to scaled, refined management demands
