On Monday, December 17, 2018, the IEEE Indonesia Section represented by Prof. Dr. Fitri Yuli Zulkifli, S.T, M.Sc., IPM donated two sets of Solar-Powered Portable Energy Storage called TaLis to Prof. Dr. Heri Hermansyah, S.T., M.Eng, Director of the Directorate of Research and Community Engagement Universitas Indonesia (DRPM UI). TaLis is portable energy storage device based on lithium ion battery and is developed by Dr. Chairul Hudaya from Department of Electrical Engineering Universitas Indonesia.
During the disaster, electricity supply often suffers from blackout due to the destroyed power generation and grids. In other hand, paramedics and volunteers who perform emergency response really need the electricity supply to run the medical or first-aid devices, lighting and other applications. To charge TaLis, a set of PV panel equipped with solar charge controller is developed so it could still be operated even if there is no electricity supply from conventional grid. TaLis consists of 18650-type cylindrical battery with total energy of ~ 700 Wh, resulted from 13S5P (65 pcs), BMS 30A, Inverter of 300 W (42-54.6VDC to 220 VAC ), DC to DC Converter 200W (48 VDC to 12 VDC), and charging input of 48V.
According to DRPM UI, a voluntarily team will be assigned to Palu next January 2019. The donation from IEEE Indonesia Section would be favorable to the team in helping local people recover from the disaster.
