EVE Energy's subsidiary in Malaysia has signed an agreement to buy lithium iron phosphate (LFP) cathode active material from Chinese LFP producer Jiangsu Lopal to guarantee feedstock supply. EVE started building the first phase of the Malaysian plant in August 2023, with an investment of $422.3mn.
[pdf] For maximum performance and longevity, LiFePO4 batteries should be maintained within their optimal temperature window of approximately 15-35°C. This range ensures efficient electrochemical activity while minimising stress-related degradation.

In LiFePO4 batteries, as soon as the cell with the lowest voltage hits the discharge voltage cut off designated by the BMS or PCM, it will shut down the entire battery. If the cells were unbalanced during discharge, this may mean that some cells have unused energy and that the battery isn’t truly “empty”. Likewise,. .
The term balancing comes from the matching of the cells by capacity and voltage, and controlling their voltages through cycling the battery to maintain the balance, or close to equal voltages at all State of Charge (SOC) levels. It is important to note that. .
LiFePO4 battery packs ( or any lithium battery packs) have a circuit board with either a balance circuit, protective circuit module (PCM), or battery management circuit (BMS) board that monitor the battery and its cells (read this blog for more information. .
Passive cell balancing is where the current entering the battery is bled off through resistors. In this scenario, the current enters the battery and fills the cells. If one cell is “full”, the resistors take that energy and burns it off (turning it to heat) so that way the current.
