Novel Battery Thermal Management System for Greater Lifetime Ratifying Current Quality and Safety Standard

Temperature excursions and non-uniformity of the temperature inside the battery systems are the main concern and drawback for any attempt to scale-up battery cells to the larger sizes as required for high power applications. The applications may include electric generating stations, substations, vehicles, telecommunications installations, large industrial and commercial installations, large uninterruptible power supply (UPS) installations and renewable energy plant installations etc. The capacity of the battery pack increases as the operating temperature is raised for a battery pack however this come with the very high expense of accelerated capacity fade i.e. ageing. Subsequently the lifetime of the battery system is reduced. Moreover poor performance (limited capacity availability) is observed at low operating temperature. In addition, excessive or uneven temperature rise in a system or pack reduces its cycle life significantly.
