DC energy meter
In order to achieve the goal of carbon peak and carbon neutrality, countries are paying more and more attention to environmental protection and green energy. Electric vehicles are currently one of the hottest topics, and charging piles as supporting equipment are also ushering in a period of rapid development.
From ordinary slow charging to super fast charging, the variety of charging piles is dazzling.
In the charging pile, if the electricity is measured, the electric meter is indispensable.
If you want fast charging, you must use DC charging. The charging equipment in the market needs to convert the current into AC metering whether it is connected to the Internet or energy storage. The loss caused is unfair to customers and equipment providers.
German "Eichrecht" regulations stipulate that consumers should only pay for the provided DC power supply. Standards are established not only at the European level, but also at the international level.
Super fast charging shortens the charging time to only a few minutes. The charger manufacturer converts AC power to direct current (DC) outside the car, bypassing the on-board charger (OBC), and directly powers the battery pack of the electric vehicle.
This method can increase the charging power to 400 kilowatts.
However, this conversion phase will generate power loss, and the end user (ie, the owner of the electric car) does not have to pay for this.
Therefore, an electric meter was placed after the conversion phase to monitor and bill the exact energy transferred to the electric vehicle.
Yongtailong has launched a DC meter that can directly measure DC power, which can be specifically designed for use in electric vehicle DC charging pile application scenarios, reducing the customer's payment for losses and making every penny of the customer have use value!
