I&#39;ve been doing 220volt 15 amp charging to cool the battery. Like Tom, I manually stop it when the battery temp reaches 80F. Like Mark, I found that low amp charges didn&#39;t cool the battery as much - I&#39;ll speculate that Tesla probably sees the low amperage and figures that it can&#39;t waste as much juice cooling the battery, and that a slow charge won&#39;t really heat it up much.<div>
<br></div><div>Have you thought about parameters for the CoolDown function?</div><div>- Desired End Temperature</div><div>- Amperage to Use</div><div>- Maximum length of time to run</div><div><br></div><div>Also, have you considered an &quot;Auto&quot; feature, where when OVMS sees the car is plugged-in but not charging and that the battery temp is high, automatically kicks on to cool it? The max run time parameter is kind of a safety feature to avoid running too long at high prices.</div>
