thing is currently with my ICE I only fuel up at most only once or twice per month, no it's not a hybrid. I WFH full time actually so I mostly only drive my car during weekends. For additional context, I bought my current car last year Sept and till date the mileage is only 9.5k. yep... not even 10k after 1 year ownership
so honestly speaking not sure if EV would even make sense for me in terms of savings. But if I wanted to try something new and experience the tech then yeah
for LFP is it necessary to charge to 100% every week? since I only drive during weekends, I assume i would consume at most only around 10 - 20%. Based on this technically a full charge could last me 2 - 3 weeks (almost similar to full tank of my current car). In this case can I wait until the battery level is around 30% (I know it's bad to let it go below 20%) only charge? And is this the same practice for NCM battery?
Yea, considering your low usage, EV might not be that suitable for your use cases. EV is most suitable if you’re heavy user and constantly using it. Active battery are healthier than a battery that is mostly kept dormant and rest there unused.
Anyway, to answer your questions :
- No, it’s not necessary to charge to 100% for LFP. It’s only okay to frequently charge it to 100% but it’s not a must, up to you. Tesla recommends to charge to 100% once a week in order for BMS to recalibrate for more accurate SoC display, due to the characteristic of voltage in LFP which makes estimating the SoC harder.
- You should also change your mindset on “refueling” your EV. For EVs, charge it as frequent as you like, there’s no need to wait it drop until certain percentage and recharge. Batteries are happier if it gets small “top up” frequently. Same for both LFP and NMC.
