Abstract

The focus of this article is to make a comparison between temperature-regulated and uncontrolled charging methodologies in an attempt to decide which of these is appropriate for enhancing battery performance while significantly reducing charging time. Temperature-controlled pulse charging (TRPC) and constant current (CC) charging techniques have been evaluated. The temperature of the battery increases in proportion to the magnitude of the current injected during CC charging and cannot be governed without external cooling. The performance measures are the effect on the State of Health (SOH) as well as the expected lifespan of the battery. The computation employs 12.8 V, 40 Ah Lithium-Ion (LiFePO4) batteries to demonstrate that increasing the temperature relation of control leads to greater charge submission at the same charging rate.
