Application of ADW300 wireless meter in NIO battery swap station

ADW300 wireless meter, NIO battery swap station fee settlement + operation and maintenance

Hardware	ADW300/4G
Project Amount	>300000$,maintain a purchase volume of 1,000-1,500 units per year

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

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

Acrel ADW300A IoT Power Meter For Global Low‑Voltage End‑Circuit Sub‑Metering

Against tightening global energy‑saving regulations such as EPBD, ISO 50001 and ASHRAE 90.1‑2025, system integrators face real‑world challenges in low‑voltage end‑circuit sub‑metering: cabinet‑space constraints, mixed new‑build & retrofit sites, mismatched current sensors and diverse communication infrastructures. This article introduces Acrel ADW300A series DIN‑rail IoT power meter, supporting 5A secondary CT, split‑core CT and Rogowski‑coil sampling, with RS485, WiFi, LoRa, LoRaWAN and regional 4G uplink options. It delivers multi‑parameter measurement, harmonic analysis, historical‑data logging and hardware‑based extension functions. Real‑world project cases from Europe, Latin‑America and Southeast‑Asia illustrate deployment guidance, configuration tips and pre‑shipment & commissioning checklists for global commercial, industrial and remote‑site sub‑metering projects.
