Additional benefits from good thermal management of lithium–titanate cells include improved electrochemical performance, better charge acceptance, higher power and energy capacity, and improved cycle life. Preliminary tests revealed that the cells do not generate heat evenly throughout their volume.
Therefore, the current lithium-ion battery thermal management technology that combines multiple cooling systems is the main development direction. Suitable cooling methods can be selected and combined based on the advantages and disadvantages of different cooling technologies to meet the thermal management needs of different users. 1. Introduction
Battery electric vehicles and hybrid electric vehicles demand batteries that can store large amounts of energy in addition to accommodating large charge and discharge currents without compromising battery life. Lithium–titanate batteries have recently become an attractive option for this application.
Recent advances in Li-ion technology have led to the development of lithium–titanate batteries which, according to one manufacturer, offer higher energy density, more than 2000 cycles (at 100% depth-of-discharge), and a life expectancy of 10–15 years .
Therefore, in order to cope with the temperature sensitivity of Li-ion battery and maintain Li-ion battery safe operation, it is of great necessary to adopt an appropriate battery thermal management system (BTMS).
