Of course, if he is able to use the Lester as his on-board charger, then he can still use it at home the same as today (unless *it* fails). > I agree with you that the simplest way could be to carry the Lester > and allow it to be on-board as it works - if it can convince the > J1772 outlets (called EV chargers) to power the Lester at 240V. There should be no issue powering a Lester at 240V, provided the Lester has an AC inlet for 240VAC. The Lester has decent power factor, much better in fact than most on-board switch mode chargers that people use (e.g. Zivan, etc.). Obviously, those chargers with active PFC do even better. The only possible issue I can see possibly arising is that public EVSEs may provide anything from 208VAC to 240VAC, and I don't know how sensitive the Lester is to the precise input voltage. Worst case, it would require adding a small transformer that can be switched in to boost the line voltage to the Lester when using an EVSE that supplies 208VAC. > There may be reasons that does not work, either when power factor > of the Lester is not good enough or if there is no space for that > bulky charger in the vehicle, then it could be better to get a > modern, small and high efficient switching charger that accepts > 240V (or both 120/240) and can charge his 120V pack. Yes, agreed; if he is willing to invest in a second charger, then this is definitely preferable to losing the passenger footwell to the Lester. EVers are often reasonably "thrifty" people, so I thought Scott might be interested to know that using his existing charger is a possible alternative to buying a new one at this time. > Personally I am happy with my 120V charger since I can plug > into a 120V outlet at all places that matter to me, Although my onboard charger(s) can accept 85-265VAC, I too charge almost exclusively from 120VAC. However, now that we have a J1772 EVSE at work, I am seriously tempted to add a J1772 inlet just so that the charging station will be seen in use regularly ;^> Cheers, Roger. _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
