How Electric Prepayment Meter Is Developing And Iterating?- Zhejiang Yongtailong Electronic Co., Ltd

Electric Prepayment Meter, which means pay as you go, first paying to purchase electricity and then using electricity. Prepayment is an indispensable mode in the type of electricity meter. Effectively solves the problem of difficult charging and deeply loved by power generation enterprises and power operators.

In Africa and Southeast Asia, the problem of difficult electricity charging is very prominent, basically using Electric Prepayment Meter, and unifying the highly safe standard STS standard. At the level of the government power bureau, the use of smart prepaid energy meters in China is relatively small, and it has become a downward trend year by year.

In African countries, BS keyboard single-phase Electric Prepayment Meter and BS keyboard three-phase Electric Prepayment Meter are used, and China's smart Electric Prepayment Meter are mainly IC card-type smart Electric Prepayment Meter. From the birth of the card smart prepaid meter, it has undergone many upgrades and iterations.

China's smart Electric Prepayment Meter has entered multiple stages of development, and the earliest use of electric key IC cards is not high, there is a risk of cracking, and it is mainly used in property communities. In 1995, the security of telephone IC cards and logic encryption cards (4442\4428) was greatly improved, and the scope of use was expanded to power management departments. Around 2000, it was upgraded to a financial-grade IC card, that is, a CPU card, embedded chip and ESAM encryption module, and the security was further improved and promoted nationwide.

In addition to the use of power bureaus, China's Electric Prepayment Meter are also used in the secondary market, such as rental housing, market shops, school dormitories, factory dormitories, etc. In the secondary market, it is mainly based on din-rail single-phase Electric Prepayment Meter and din-rail three-phase Electric Prepayment Meter, giving full play to the advantages of small size and convenient installation of DIN rail meters. In terms of data security, AES encryption is generally adopted, and STS encryption is rarely used. Data collection and power recharge through communication. With the development of communication technology, feedback on actual on-site use effects, cost factors of communication methods and installation convenience, etc., the communication methods of Electric Prepayment Meter in the secondary market are constantly iterating and optimized; RS485, WiFi, LoRa, PLC, 2G, NB-IoT, CAT1 (4G) these communication methods have certain applications, so far the market according to the installation environment is basically RS485, WiFi, 4G three communication methods.

With the rapid development of China's urbanization construction, the commercial market and housing rental market have been vigorously developed, and the scale of China's Electric Prepayment Meter market is growing day by day. According to the needs of market development, the functions of Electric Prepayment Meter is also increasing, and they are developing in the direction of intelligence, data and systematization. The emergence of digital Electric Prepayment Meter system solutions has solved the various needs of rental housing and tenants, and also promoted the application and penetration of Electric Prepayment Meter in the secondary market.
