Using Dynamic Load Management, Smart Charging system safely balances energy consumption between your electric vehicle, charging station and other devices on site. A smart energy meter is mounted on the power distribution cabinet and is used to measure the power consumption of the building, and a reserve is allocated to the charging station to charge the electric vehicle.
When the real-time energy consumption of a building is high, the charging station performs charging slowly or temporary stops charging, and when the building’s electricity consumption decreases, the charging station increases the charging capacity. Thanks to the intelligent system, you will optimally load the power input of your building, which will save you the cost of increasing the input. With the additional use of the time schedule function, you will perform charging when the price of electricity is at its lowest.
For Single Charger
While the total power consumption is close to the upper limit, the CT(current monitoring device) will timely reduce the power to ensure that the total power consumption does not exceed the upper limit.
For Multi-Chargers
Dynamic Load Management involves adding current monitoring devices (Load Balance Controller) and setting the maximum load allowed for power distribution at the operating station. The real-time monitoring device checks the station’s total power consumption and flexibly provides charging services to EVs through the most effective power distribution method.
Average Power Distribution (APD)
200kW total distribution capacity=10x15kW chargers+ 50 kW other electric power capacity in a commercial building.
Full-Load Priority (FLP)
200kW total distribution capacity= 50 kW other electric power capacity in a commercial building+6x22kW chargers +18kW charger
Timetable-based Dynamic Load Management
Timetable-based load management is a method of distributing available charging capacity more scientifically and reasonably based on the needs of vehicles (and even the power grid) on top of dynamic load management.
It dynamically monitors the currently available power and allocates charging power according to the priority of the vehicle’s travel schedule and the SoC state of the vehicle’s battery, ensuring that each vehicle is fully charged when needed.
This method is suitable for charge stations that share power distribution capacity with other electrical devices and have chargers of different types and power levels. Priority/time-based charging is ideal for fleet operation.
Cloud Load Management
On Site Solution
The AP mode can configure individual chargers and set the maximum charging current, optimizing charging capacity and preventing overload protection.
Network Solution
The Evchargo cloud platform can be used for network-based solutions for charge point management. The scalable software can optimize charge point operation, improve availability, and enable accurate charging billing through the OCPP protocol. A rule-based load management system can distribute available connection loads to all charge points, enabling on-demand charging for EVs and optimizing charging capacity operation and overload protection for building facilities.
