Lithium ion battery application for regenerative energy utilization in traction power supply system

摘要

Stationary Energy Storage System (SESS) using Lithium ion (Li-ion) batteries have been in operation in Japan and abroad for the purpose of introducing against regeneration canceled and compensation for a voltage drop, energy saving. This report is made on the effect of energy saving of the SESS based on a case of the introduction of the SESS in Horinouchi Substation of Keio Corporation out of the SESSs Hitachi has supplied in the past.
