LEAFfan said:What Nissan means is IF the battery pack temp is in the RED, then allow it to cool before charging. If it's within the other colors, charging right away is no problem. Think about it. It wouldn't make sense when you are out driving around and need a charge, whether L2 or QC, to say you shouldn't charge right away.
Please wait while we find an agent to assist you...
You have been connected to Eric W.
Eric W: Thank you for contacting Nissan LEAF Consumer Affairs. How may I assist you?
JP White: Hi I've been reading the Owners Manual and have a question regarding some advice it gives......
Eric W: Go ahead.
JP White: ..... On page EV-22 it says to let the batery cool after use prior to charging. Does that apply even if the battery temp is in the normal range?
Eric W: The intention is not to attempt to charge the battery if the temperature of the battery is above a certain point at which charging could be detrimental to the battery.
JP White: Normally it maintains 'six bars' on the temperature gauge. Is that an acceptable temp to begin charging or should one wait anyway?
Eric W: Just a moment please.
JP White: k
Eric W: It should be acceptable to charge the vehicle if the battery temperature gauge shows that the battery is within normal range (between the blue and red gauge squares.
JP White: OK Thanks. That answers my question
Eric W: Is there anything else I can assist you with today?
JP White: No Thanks. I appreciate your help today.
Eric W: Thank you for contacting Nissan LEAF and have a good day.
Stoaty said:A better reason to wait to recharge is to keep a lower average SOC over time. Why have the battery sitting at 80% (or especially 100%) for many hours every day when a 40-60% SOC is thought to be optimal for battery life. This is especially true if the ambient temperature (and thus the battery pack temperature) is high.
I'm not sure where this came from. There is good indication that 80% charge is close to true 80% SOC. According to research papers done on manganese spinel cells, anything above 60% SOC gradually accelerates aging due to the dissolution of manganese into the electrolyte. While there is strong indication that the battery pack will perform well, it's too early too tell. Keeping the average SOC down is a conservative recommendation, nothing more than that.GaslessInSeattle said:I think this is splitting hairs, IMHO. We are talking 80% of something like 80%.
Can we presume you are leasing then?TangoKilo said:9,350 miles and counting... I charge to 100%, 100% of the time. I generally plug in as soon as possible, whenever there's an EVSE available. The temp increase, if any, is negligible. As is any range degradation....
ovev said:In cold areas, would it be best to use an end timer set closely to the departure time? Then the battery should be warm from the charging process and should give some better range.
That is very impressive then. You are perfect test candidate for the LEAF and I'm sure many are happy to hear you are not just doing it because you don't care about the car/battery in 3 years and the person that may get it.scottf200 said:Can we presume you are leasing then?TangoKilo said:9,350 miles and counting...
