EM613001 200A 40-400V Din Rail Smart Shunt RS485 DC Power Monitoring EV Charger Smart Meter

Product Details

1.There are 4 models of DC meter:EM613001/EM613002/EM619001/EM613005. It's worth to highlight that RS485 & NB-IOT communication are optional. 

2.EM series DC energy meters are designed for measuring and monitoring in DC systems. 

3.The din rail DC energy meters can measure of important DC parameters: Voltage, current, power and energy etc. It also support bi-directional measurement. All data in the meter are accessible via RS485 using Modbus RTU/DLT645. 

4.The meter working with DC power supply. Input voltage range up to 1000VDC, and current inputs are flexible with DC shunt. 

5.The multi-tariff version has a RTC equipped inside, it can provides multi-tariff information and monthly records.

6.EM series dc meter is designed for scenarios such as DC panel, battery storage system, solar PV, EV charger and telecom base stations.

Product Application

Today's public charging infrastructure mostly supplies alternating current (AC). This leads to a long charging time of eight hours on average, due to a low power capability of around 44 kW. To reduce this charging time to only a few minutes, charger manufacturers convert the AC into direct current (DC) outside the car, bypassing the On Board-Charger (OBC) and supplying the battery pack of the electric vehicle directly. Although this method boosts charging power up to 400 kW, this conversion stage generates power losses, which should not be billed to the EV owner. Thus, an electric meter is placed after the conversion stage to monitor and bill the exact energy transferred to the electric vehicle, rather than the charge duration.

The DC energy meter is a key component in the EV ecosystem. It must precisely measure and record the power (voltage and current) delivered from the EVSE to the vehicle, compensating for cable losses, and then securely transmit the data upstream to ensure accurate billing.EM613001 is such a smart and compact DC Billing Meter, fully compliant with the German Eichrecht regulation. Fast chargers for electric vehicles make use of DC charging; they convert the power before it enters the vehicle. It is suitable for power measurement and power metering of DC signal equipment such as EV charging piles. No matter it’s DC fast charging station or DC EV charger, if you want to know the electrical parameters then DC energy power meter is necessary.
