Dynamic Load Balancing (DLB): Intelligent Power Management
DLB (Dynamic Load Balancing) is an intelligent power management technology that monitors household circuit current in real-time. Using the total current as the judgment basis, it automatically adjusts the charger's output power to ensure the total current never exceeds the safe carrying limit — effectively avoiding circuit breaker trips, equipment damage, and potential safety hazards caused by overloading.
- Total Current (Customer Input)
- Sets the maximum current capacity per phase (e.g., 80A) for the home circuit. Adjustable from 8A to 99A. Any excess beyond this value will cause the circuit breaker to trip.
- Charging Current
- The real-time current drawn by the EV charger during active charging sessions.
- Home Appliance Load
- Total load of all household appliances in the circuit, excluding the charging station itself.
- Standby Current
- Calculated as: Total Current - Home Appliance Load - Charging Current. This represents the available capacity buffer.
DLB Configuration: Step-by-Step Setup Guide
DLB Hardware Integration: Smart Meter Connection
The Dynamic Load Balancing system requires a compatible smart energy meter connected to the charging station via signal cable. The meter continuously monitors total household current consumption and transmits real-time data to the charger, enabling intelligent power adjustment to prevent circuit overload.
- Compatible with standard single-phase and three-phase energy meters.
- Signal cable connection between meter and charging station (included in DLB package).
- Real-time current monitoring with response time under 100 milliseconds.
- Automatic power reduction when approaching total current limit.
- Manual override available via LCD menu or mobile app if needed.
- Professional installation recommended to ensure proper meter integration.

Automatic Temperature Protection: Intelligent Thermal Management
Advanced temperature monitoring continuously tracks both the charging plug and control box temperatures. When the system detects overheating (85°C threshold), charging automatically stops to prevent damage. Once temperatures cool to 65°C, charging resumes automatically — no user intervention required.
- Automatic power cutoff at 85°C to prevent thermal damage.
- Automatic resume at 65°C when temperatures return to safe levels.
- Dual-point temperature sensors monitor both plug connector and control box.
- Real-time temperature display on LCD screen during charging sessions.
- Prevents cable degradation and extends equipment lifespan significantly.
- Complies with international thermal safety standards for EV charging equipment.
Smart Scheduled Charging: Maximize Cost Savings
Program weekly charging schedules via the mobile app to automatically charge during off-peak electricity rate periods. Set recurring plans that run on autopilot — your EV charges overnight when rates are lowest, potentially saving hundreds of dollars per year on electricity costs.
- Set specific start and stop times for each day of the week.
- Create different schedules for weekdays and weekends automatically.
- Recurring weekly schedules run without daily intervention.
- Take full advantage of time-of-use electricity rate plans.
- Visual timeline editor makes scheduling intuitive and easy.
- Manual override available anytime via app or front-panel buttons.
