DC billing meters
The DCS-I series is a compact design commercial DC billing meter designed for the DC microgrid future market.
Sensway-DCS series can measure DC current using an external DC current sensor with open-loop digital isolation technology designed as a split-core type or a solid-core type on a busbar or cable depending on the installation method of the primary conductor.
The rated current ( 0 -4000ADC) is also available as an option.
The DC voltage sensor has a built-in DC voltage sensor with digital isolation technology in the DCS series(DC Billing Meter), allowing you to measure DC voltage in the 0-1500VDC range without using an external DC voltage sensor.
The DCS series is the world's first DC billing meter using the most advanced digital insulation technology for DC voltage and DC current measurement methods.
Billing On The DC-Side
Currently, AC is universally used for power generation, transmission
and distribution grids worldwide, but with upcoming technologies for electric vehicles (EVs) and energy storage in general, direct current is playing an increasingly important role.
Imagine a solar power plant with electrical energy storage and DC-car charging.
There is no AC/DC conversion loss except for some auxiliary
AC power sources such as street lights.
But, how to bill the energy? Most electronic energy meters are designed for AC power,
DC charging piles will still measure on the AC side on a time basis or when connected to the grid and will be charged accordingly. Both methods have uncertainties.
Time-based DC fast charging costs are guesswork only. Battery charging is not linear.
Cost savings come from larger car batteries and lower battery states,
while car owners with smaller batteries and higher state of charge overcharge.
Some countries are already raising concerns about billing methods.
With AC metering, conversion losses must be taken into account. This can be a loss in the range of 6% to 9% compared to the energy recorded by the car.
A DC meter is required for accurate billing. We have developed a DC billing meters specifically for fast charging piles.
This allows users to charge or monitor recorded energy in both directions (feed or charge to the grid).
