Smart Uninterruptible Power Supply (UPS) System

Technology Overview

The Smart UPS system features a fully-modular system which is scalable and portable based on user’s need. It is a portable and modular power system consisting of a master control unit, accompanied by slave battery power units. The master control unit has a touch-screen LCD control panel, power inverter, battery charger and telemetry system. The slave battery power units consist of the battery pack, battery management system and active battery balancing technology.

Technology Features & Specifications

This system targets consumers and companies interested in portable AC power via lithium-ion battery. It comprises a single-phase modular system controlled by a master control unit where the battery module can be added. In this smart UPS, an intelligent battery management system (BMS) based on micro-controller technology is designed and developed. The system consists of monitoring, protection and communication subsystems. The BMS will incorporate innovative AI algorithms for active cell balancing, State of Charge (SOC) and State of Health (SOH) prediction techniques, as well as real-time system monitoring and the operation status of the battery stack. Essentially, the BMS will be able to:

  • Measures and stores all cell voltages, currents and temperatures
  • Evaluates and analyses data collected during the operation of BMS
  • Improves battery endurance, reliability and lengthens the battery lifetime via active cell balancing
  • Keeps track of charges in and out of the battery, cycle count and production number
