It is largely untested (beyond simulation on my bench). When the cooldown command is given, it looks to see if a charge is currently in progress and if so remembers the details of that charge (mode, current, etc). After cooldown has completed, it will resume any previous charge that was in progress. So, I think if you want to do a cooldown without a subsequent charge, then the sequence would be to stop charge then cooldown.</div><div class=""><br class=""></div><div class="">Cooldown does use two parameters:</div><div class=""><br class=""></div><blockquote style="margin: 0 0 0 40px; border: none; padding: 0px;" class=""><div class="">xtr cooldown.timelimit 60</div><div class="">xtr cooldown.templimit 31</div></blockquote><div class=""><br class=""></div><div class="">If the cooldown has been running more than cooldown.timelimit, or the battery temperature falls below cooldown.templimit, it will terminate the cooldown.</div><div class=""><br class=""></div><div class="">Can you try again, from a plugged in but not charging state, and check ‘vehicle status’ and the info logs to see progress?</div><div class=""><br class=""></div><div class="">Regards, Mark.<br class=""><div><br class=""><blockquote type="cite" class=""><div class="">On 11 Sep 2018, at 8:47 AM, Stephen Casner <<a href="mailto:casner@acm.org" class="">casner@acm.org</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div class="">Last evening I returned home from a trip and decided to try the<br class="">"charge cooldown" command to cool the battery on my Roadster.
