Project

#1 - ADW300 Wireless Meter, NIO Battery Swap Station Fee Settlement + Operation and Maintenance

Project Overview:

·Customer: NIO

·Country: China

·Application Features:scenario-based,leased sites(0.5S-level accuracy requirement), multi-site operation and maintenance (dispersed 4G communication)

·Project Amount: >300.000 USD

·Project situation:NIO car swap stations need to pay electricity fees to the site. Manual meter reading is troublesome and settlement is difficult. We use our ADW300/4G to directly transmit data to the NIO platform. The platform compares and verifies the electricity uploaded by the meter with the electricity sold by the order system. Within the allowable error, NIO will bill the electricity bill with our meter reading and settle the electricity fee with the site.

Technical features:

1.Two-way authentication: TLS encryption, one machine and one key (each device is registered separately, and the key is independent)

2.Data encryption: Protobuf data format + AES encryption

3.Support platform to send parameters such as rate and ratio

4.Support OTA upgrade

5.Support real-time upload of alarm status

6.Freeze the power and maximum demand of the last three months

#2 - ADW300 wireless meter,Lawson convenience store online energy monitoring

Project Overview:

·Customer: Lawson China

·Country: China

·Application Features:chain stores, multi-site energy consumption monitoring, centralized management(4G communication),renovation projects(advantages of open current transformers)

·Project Amount: >300.000 USD

·Project situation:The project covers Shanghai, Guangdong, Liaoning, Sichuan, Chengdu and other regions. It mainly monitors the energy consumption of each store, energy consumption data reports, regional energy consumption reports, and realizes centralized control and settlement of energy consumption data. The project adopts our EIOT solution, a domestic chain convenience store electricity monitoring project, and has transformed more than 3,000 stores across the country.

Technical features:

1.Use the ADW300-HJ-DXX-4G solution for fast construction and installation. In this project, the instrument upgrade adds a phase sequence detection function, which facilitates remote observation of construction quality and timely proposals for line changes.

2.The platform outputs energy consumption data reports by year and month, regional energy consumption analysis, year-on-year and month-on-month data.
