Concerning environmental impacts, studies on assessing charging strategies found an overall GHG reduction over the life-cycle of BEVs by shifting charging hours into times of low carbon electricity generation, i.e., hours with a high share of RE and feeding back in times of low RE availability (e.g., [13, 33, 77]). Following previous
A battery protection unit (BPU) prevents possible damages to the battery cells and the failure of the battery. Such critical conditions include: Over-charge: is when the battery is charged over the allowed maximum capacity. High & low temperature: is when the internal temperature of the battery cells exceeds their safe operational temperature
EVs have become more economical and attractive than ever before, with more car companies offering hybrid or full-battery electric vehicles. The battery is what makes an EV possible, typically a lithium-ion battery. And much like traditional, fossil fuel-powered internal combustion engines, these batteries are made from limited natural resources.
