Specifies context for interpreting percent values:<br/>0 - N/A<br/>1 - %setMaxW<br/>2 - %setMaxVar<br/>3 - %statVarAvail<br/>4 - %setEffectiveV<br/>5 - %setMaxChargeRateW<br/>6 - %setMaxDischargeRateW<br/>7 - %statWAvail<br/>8 - %setMaxVA<br/>All other values reserved.<br/><br/>For %setMaxVar, if the device supports both setMaxVar and setMaxVarNeg, then %setMaxVar uses the percentage of setMaxVarNeg for negative values. If the device only supports setMaxVar, then %setMaxVar uses the percentage of (-1 * setMaxVar) for negative values.<br/><br/>For %setMaxW, if the values are negative, %setMaxChargeRateW is used. For %setMaxW, if the values are positive, either %setMaxW or %setMaxDischargeRateW can be used.<br/>
