For countries that pay high attention to industry, the largest share of electricity consumption is undoubtedly heavy and light industry.In the industrial field, the operation of machines, the control of computers, monitor of energy quality... can not be without the participation of electricity.Industrial electricity is different from residential electricity and commercial electricity. It refers to electricity used by enterprises mainly engaged in large-scale production and processing industries.
In response to industrial electricity demand, IVY launched a series of energy meter which comply with IEC (Short for International Electrotechnical Commission standards) such as IEC62052-11,IEC62053-21,IEC62053-22,IEC62053-23,IEC62055-41,IEC62055-51.The measuring devices including single phase/ three phases meter, basic meter, multi-functional meter, smart prepayment meter, suspension meter, STS meter, GPRS meter, PLC meter, DLMS meter, 21 channels meter, smart sensor, fire detector, breaker and so on can be used in industrial area for energy management.
AC DC EV Charging Metering Solution
According to the charging method, charging piles are divided into three types: AC charging piles, DC charging piles, and AC-DC integrated charging piles.
AC charging pile: A power supply device that provides AC power for on-board charging of electric vehicles. In other words, it is slow charging. Generally, the output power of slow charging is relatively small, and it takes 5-8 hours to fully charge.
DC charging pile: a power supply device that provides low-power DC power for electric vehicles. That is what we often call fast charging. The output power of fast charging is large, and its charging power is large (60kw, 120kw, 200kw or even higher). The charging time only takes 30-120 minutes, which is relatively fast.
AC-DC integrated charging pile: AC-DC integrated means that it can provide both DC charging and AC charging. Generally speaking, it is generally used less in the market because the cost is too high.
According to the market demand of charging piles, IVY METERING has developed AC DC charging meters respectively. It can meet the different requirements of different charging piles for electric meters. 0.25-5(30)A, 5(32)A, 5(40)A, 5(50)A, 5(80)A, 5(100)A, 10(240)A, 2000A
Vehicle-to-Grid (V2G for short) and Vehicle-to-Home (V2H) are two important examples of this evolution, with the charging station serving as a central regulator for the energy flows between the electric car, the distribution network, and the home. V2G technology enables users to effectively reduce the cost of using electric vehicles, and in the event of natural disasters, etc., V2G technology can also be used to use electric vehicles with power output functions as emergency power sources, which virtually increases the use of electric vehicles , so as to promote the production and sales of electric vehicles. For the power grid company, it can not only reduce the pressure of electricity consumption caused by the large-scale development of electric vehicles, but also use electric vehicles as energy storage devices to regulate loads, improve the efficiency and reliability of the power grid, and reduce the cost of energy storage construction for the power grid investment.As a smart grid technology, V2G describes the relationship between electric vehicles and the grid, and regards electric vehicles in a stopped state as distributed energy storage units. , through the two-way communication between the electric vehicle and the grid, the two-way energy flow between the electric vehicle and the grid is realized.
The charging pile needs to meet the V2G function, which will increase the requirements for the electric energy meter, and the IVY METERING charging pile electric meter can fully meet the requirements.

First of all, everyone must understand that in a distributed photovoltaic power station, if bi-directional metering of power consumption and power generation is to be realized, the traditional method is to use two one-way meters to measure power generation and power consumption separately, which not only increases the cost of use and Wiring is difficult, and future use or maintenance also becomes complicated.
The bi-directional meter is mainly aimed at users who need bi-directional metering in distributed photovoltaic power stations. When the electricity generated by the photovoltaic power station is surplus, the electric energy delivered to the grid needs to be accurately metered. In addition, when photovoltaic power generation cannot meet the needs of users, the electric energy used in the grid also needs to be accurately metered. However, ordinary single-block unidirectional meters cannot meet this requirement, so it is necessary to use smart meters with bidirectional metering functions to realize bidirectional metering of electric energy.
In order to meet the needs of grid-connected photovoltaic solar power generation for electric energy meters, IVY METERING has developed the "PV" series electric meters, which include two different situations of AC and DC, which can solve problems that traditional electric meters cannot solve.
(1) Bi-directional metering
(3) Four metering modes
(4) MID approval
(5) Built-in battery and multi-tariff
(6) DIN rail, small size, easy to install
The net meter system refers to the use of bi-directional metering technology to connect its own power generation equipment with the power grid of the power supply company to realize the renewable energy power application mode of self-use and surplus power connected to the grid. The content of the net meter system mainly includes the following aspects:
1. Billing of electricity consumption: The net meter system adopts bi-directional metering technology to carry out net settlement of the electricity in the system, that is, the difference between the electricity generated by the home and the electricity consumption is used as the actual electricity consumption for billing. If the self-generated electricity is greater than the electricity consumption, the excess electricity can be sold to the grid; if the self-generated electricity is less than the electricity consumption, the electricity needs to be purchased from the grid.
2. Network access and grid-connected management: The net meter system requires that one's own power generation equipment be connected to the grid through inverters and other devices, and realize the bi-directional power transmission function between the grid and the system. Relevant departments will carry out network side protection, security testing and user information management on the access system to ensure the safe and stable operation of the system.
3. Safety management: The net meter system requires that the system connected to the network must meet the safety standards of electrical equipment, and the equipment interface should have safety protection measures such as anti-theft, lightning protection, and fire prevention to ensure the safe operation of the system. Users must abide by relevant electrical safety standards to avoid personal injury and equipment damage caused by improper operation.
4. Renewable energy subsidies: In the net meter system, the government will provide certain subsidies to users who use renewable energy to generate electricity according to local renewable energy policies. These subsidies are mainly used to promote the development and application of renewable energy to achieve sustainable development.
In short, the net meter system is to promote the application and development of renewable energy by establishing a bi-directional metering technology, realizing self-generated and self-consumption, and surplus electricity connected to the grid. network management, security management, and renewable energy subsidies.

Lorawan power meter alao can be named as Lorawan electricity meter, Lorawan energy meter, which is a kind of electricity meter with LoRaWAN communication module. The Lorawan energy meter usually works with Lorawan gateway and Lorawan network server by Loramesh networking, and the users can read out the power information via APP or PC. The principle of Lorawan energy meter as follows:
Application of LoRa energy meter and advantages:
1.LoRaWAN electricity meter for utility
In most situations, utility connectivity networks require small payloads of data from daily index to every ten minutes logs with data throughputs of several kilobits. Some specific use cases— like breakers for electricity, prepayment systems, or services supported by remote valve control — can justify a need for a low latency. For the use cases requiring latency of 1 second or more, LoRaWAN can perform well enough to support the automation system requirements.
LoRaWAN network infrastructure deployment and maintenance occurs at a much lower cost compared to traditional WMBUS, cellular technologies and proprietary ones, due to the high link budget and long range performance of LoRa radio that enables wide area network deployment. For instance, LoRaWAN applications for water and gas meters can currently support battery life of over 20 years when transmitting once per day.
Since utilities are responsible for the infrastructure and the distribution of electricity, gas, and water, they are considered critical infrastructure and national or regional regulators demand a high level of security. LoRaWAN specification applies 128-bit Advanced Encryption Standard (AES) algorithms to provide two-layered end-to-end encryption to protect the confidentiality of the payload during the network transport and the device authentication for network security. Utilities can profit from this end-to-end security layer to protect all data communications within meters and other IOT devices connected to a LoRaWAN public network. Hence Lorawan electricity meter are purchased by utilities as well.
2.LoRaWAN energy meter for Smart City
LoRaWAN® is the solution for many of the challenges that Smart Cities face and is particularly suited for smart city applications that would benefit: Communicating across distances ranging up to 15kms, Low operation and maintenance costs etc. LoRaWAN and LoRaWAN energy meter adds a dedicated purpose-built network for the Internet of Things applications, freeing up other city communication infrastructure to be more cost-effectively utilized, more efficiently employed and to realize greater returns on investment (ROI).
3.LoRaWan power meter for smart building
LoRaWAN has already become the de facto wireless protocol for smart buildings by providing low power, long range connectivity within large-scale commercial implementations. LoRaWAN allows building managers, owners, tenants and service providers to view building functions remotely and ensure all the things within the building work in harmony. Lorawan power meter is an measurement instrument in this loop.

Energy saving means to "save energy and reduce consumption".
To realize energy saving, we need to start from the following aspects:
1.Replace the old with the new device-- improve energy efficiency, eliminate energy-consuming electrical equipment and replace it with advanced and efficient equipment, so as to improve the internal efficiency of electrical equipment honestly.
To replace and eliminate old and energy-consuming equipment by means of technological innovation, scientific and technological progress and the development of The Times, so as to achieve the purpose of energy conservation.
For example, replacing incandescent light bulbs with energy-saving lamps, replacing traditional electricity meters with high accuracy smart meters, and replacing AC motors with DC motors can all produce very significant energy saving benefits.
2.Improve the process -- improve the comprehensive utilization of energy.
3.Strengthen maintenance -- Reduce loss By adopting more advanced and scientific maintenance equipment and technology, reduce the loss of energy-using equipment and reduce the maintenance cost of energy-using equipment, so as to effectively reduce the energy consumption expenditure of enterprises.
4.Add energy saving device -- reduce energy consumption add frequency converter to achieve the purpose of electricity saving.
5.Off-peak power consumption -- reduce the cost and adjust the power consumption time reasonably, actively make use of the difference between peak and valley electricity prices, and transfer part or all of the peak power consumption time to the off-peak time.
In terms of air conditioning and refrigeration, ice storage technology can be used to transfer power consumption time. Although this method does not save electricity, it can save money by taking advantage of the difference in peak and valley electricity prices.
6.remote monitoring, computer science can use computer remote monitoring technology, monitoring of energy-using equipment in time, can use status, analyse and judge the operation state of energy-using equipment, scheduling energy load reasonably, can use the equipment in the prolonged state can best use, according to the principle of "required for" science can use, realize the terminal energy-using equipment scientific management and effective utilization of energy.
