With detailed data from OBDII (see this post) I've started thinking about ways to track the health of our HV batteries.  But first, some of the data available from the Battery Energy Control Module (BECM) is: Battery Age:  Mine is 23 months - sounds right for car built in April 2013. Battery voltage:  Runs about 282V.  A 5 minute run gave min/max of 264V/303V. Battery Current:  Varied from -114 amps (charge) to 94 amps (discharge).  Limits (see below) should be about +/-120 amps.
