Detailed Description

Calculates a battery's charge level given its voltage using a model of its discharge curve.

Note that this is not an optimal way of measuring remaining battery capacity. It would be better to base it off of how much current has been drained from the battery so far, but we don't currently measure that, so we approximate charge level from voltage.

Constructor & Destructor Documentation

BatteryProfile()

BatteryProfile::BatteryProfile

(

std::vector< BatteryProfile::Entry >

dataPoints

)

Construct a battery profile with the given <voltage, charge level> pairs.

These MUST be sorted in order of increasing voltage.

Member Function Documentation

getChargeLevel()

double BatteryProfile::getChargeLevel

(

double

voltage

)

const

Get the charge level given the voltage.

The voltage curve is represented by a piecewise linear graph based on the data points given in the constructor.

Parameters

voltage

The voltage of the battery

Returns

A value between 0 and 1 indicating charge level
