Development of mobile power hub with Retired Electric Vehicle Batteries

I&T Solution Development of mobile power hub with Retired Electric Vehicle Batteries
(REF : S-0590)
Solution Feature
  • Although these retired batteries are not suitable for supporting electric vehicles, their State of Health is about 70% to 80% which is good for other equipment with low power demand. This project aims to provide a second life to these retired batteries by repurposing.
  • The mobile power hub shall be served as backup power supply and it shall be suitable for indoor and outdoor environment, such as Central Battery System in buildings, generators in buildings and construction sites, temporary power supply, etc.
  • the requirements: (a) Suitable for indoor and outdoor operation; (b) Equipped with socket outlets which support output voltage 220V/380V and output power of not less than 10kVA;(c) Completed with a control system, inverter system and a battery charger
  • (d) The control system shall examine the voltage, frequency, phase angle and transient of the energy storage system to ensure safe operation of the energy storage system; (e) Completed with battery monitoring system for monitoring of the performance of each cell
Trial Application and Expected Outcome
  • The mobile power hub shall be served as backup power supply and it shall be suitable for indoor and outdoor environment, such as Central Battery System in buildings, generators in buildings and construction sites, temporary power supply, etc.
  • a. re-package the retired batteries b. Develop the condition motoring unit for the retired batteries c. Develop the control system for the overall system d. Develop the integration of the retired-battery backup power system e. Prototyping
  • The following tests shall be conducted including, but not limited to, individual battery terminal voltage, internal impedance, ambient temperature, internal battery temperature, status of charge and float current; and Completed with electrical and mechanical protections including, but not limited to, short circuit, abnormal charging, overcharge and vibration.
