Methods

(inner) applyRatio(cost_ppm, ratio_value) → {number}

Source:

for user supplied mpg or electric range we want to apply a ratio to the official figures

Parameters:
Name Type Description
cost_ppm number
ratio_value number
Returns:
Type
number

(inner) checkRequiredKeys() → {struct}

(inner) costForFullCharge(battery_total_capacity_kwh, elec_pp_kwh) → {number}

Source:

calculate how much for a full charge of electric based on battery capacity and cost per kwh. The amount of electricity supplied by the chargepoint is calculated from WLTP efficiency and is equivalent to usable capacity plus losses. On some cars this figure happens to be close to Total capacity so we use that as a proxy.

Parameters:
Name Type Description
battery_total_capacity_kwh number
elec_pp_kwh number
Returns:

(inner) costForFullChargePPM(cost_for_full_charge, battey_range_miles) → {number}

Source:

amount ppm for a full battery charge

Parameters:
Name Type Description
cost_for_full_charge number
battey_range_miles number
Returns:

(inner) costForICEPPM(fuel_pp_litre, litres_per_mile) → {number}

Source:

amount ppm for ICE based on per litre used

Parameters:
Name Type Description
fuel_pp_litre number

number

(inner) litresUsedPerMile(mpg, miles) → {number}

Source:

litres of ICE fuel used per mile

Parameters:
