Advanced Metering Infrastructure

  • What is AMI (Advanced Metering Infrastructure)?
  • AMI refers to the advanced metering infrastructure, which is a major element in the smart grid area. In this page, it refers to all the services provided to the customer such as the customer's power consumption data (including monthly/cumulative power usage, hourly rate information) remotely metered using a two-way communication network. This enables the efficient use of electrical power to both power suppliers and customers by monitoring power consumption by means of providing information to both parties.
  • Wide PLC band

    (Fast data transmission, 10Mbps)

  • International standard

    (IEEE P1901)

  • Excellent communication PLC technology

  • AES-128 encryption support

  • Multi-hop support

    (16 Step repeating)

  • ROBO mode support

    (Mini ROBO 3.8Mbps, Standard ROBO4.9Mbps, high Speed ROBO 9.8Mbps)

EV Charger V2G (Vehicle-to-Grid)

V2X means communication between the vehicle and all other elements and infrastructure,
including various interactions like V2G (Vehicle-to-Grid), V2B (Vehicle-to-Building), V2V (Vehicle-to-Vehicle), and more.
V2X enhances connectivity between energy infrastructure, making it smarter and enabling more efficient energy management.

V2G technology connects electric vehicles to the power grid and utilizes the remaining power
from the vehicle's battery to supply or sell energy to buildings or the grid.
To provide the V2G service, HPGP-based communication module is implemented in EVC.
And the EVC needs to connect to V2G platform.

Tide's chargers support two-way charging and communication to enable the implementation of V2G technology.

V2G System

OCPP 1.6

OCCP (Open Charge Point Protocol) is an open charging communication protocol developed by OCA (Open Charge Alliance)
for the purpose of charging station operation and maintenance, and is used in more than 40,000 charging stations in more than 50 countries.
Tide's charger is OCPP 1.6 Full certified.

Advantage: Increased compatibility with charging operators increases operation, manageability, and convenience
