With the soaring global adoption of electric vehicles (EVs), the charging load in both residential and commercial settings continues to grow, placing increasing pressure on power grids. Dynamic Load Balancing (DLB), as a core solution to address uneven power distribution and avoid overload trips, has become a key consideration when selecting EV charging equipment. A precise and intelligent electricity meter serves as the "data cornerstone" for achieving dynamic load balancing — the EM719028 Three-Phase DIN Rail Current Transformer (CT) Meter, with its robust performance, empowers the implementation of DLB and provides reliable metering support for various power distribution scenarios.
In residential charging scenarios, when lights, kitchen appliances, washing machines, and EV chargers operate simultaneously, the sudden peak in power demand can easily cause circuit overloads. In commercial parking lots where multiple EVs charge at the same time, fixed power allocation often leads to resource waste or supply-demand imbalances. The core of dynamic load balancing lies in real-time monitoring of power usage and intelligent resource allocation, all of which rely on accurate collection of electrical parameter data — a gap perfectly filled by the EM719028.
As the "data sensing core" for dynamic load balancing, the EM719028 boasts three core advantages that perfectly meet the needs of EV charging scenarios:
- Comprehensive and Precise Parameter Metering: Provides reliable data support for DLB. It accurately measures over 60 electrical parameters, including voltage, current, forward/reverse active/reactive power, and total apparent power. With a Class 0.5 accuracy rating, it ensures minimal data errors, allowing the load balancing system to grasp real-time power consumption status and achieve precise power distribution.
- Dual-Protocol Communication Compatibility: Seamlessly integrates with intelligent management systems. Supports RS485 communication and is compatible with MODBUS-RTU and DLT645 protocols. It can directly link with dynamic load balancing control systems, uploading metering data in real time and receiving control commands, easily integrating into residential smart grids or commercial charging management platforms.
- Flexible Adaptability to Multiple Scenarios: Easy to install and use. Features 35mm standard DIN rail mounting and a three-phase four-wire connection method, suitable for both residential and commercial power distribution systems. Its wide operating temperature range of -40℃ to 70℃ enables it to handle complex environments. Equipped with an LCD display and touch buttons, it supports automatic scrolling display (with adjustable duration, 0 to disable) and manual page turning, allowing on-site viewing of key data for efficient operation and maintenance.
Additionally, the EM719028 supports 4 default tariff rates and multiple configurable metering modes, with a pulse output of 10000 imp/kWh. It accurately records power consumption across different time periods and loads, providing long-term data references for optimizing DLB algorithms. Whether for intelligent power allocation in residential EV charging or centralized load management in commercial charging stations, it delivers stable and precise data, making power distribution more scientific and efficient.
In line with the trend of green energy, the EM719028 can also work in conjunction with solar photovoltaic systems. It accurately measures the power generated by clean energy and consumed by EV charging, helping the dynamic load balancing system prioritize the distribution of green power and reduce reliance on the grid. With an IP51 protection rating and an 18-month warranty, it ensures long-term stable operation and lowers maintenance costs.
Dynamic load balancing is the future of EV charging, and precise metering is the prerequisite for its implementation. The EM719028 Three-Phase DIN Rail Meter, with its high accuracy, compatibility, and stability, serves as the ideal partner for dynamic load balancing in residential and commercial EV charging scenarios. It ensures every kilowatt-hour of electricity is used efficiently, safeguarding intelligent power distribution and sustainable mobility.
