Energy Usage Calculator (EUC) / Kargupy
Build Version 0.8 EUC/Kargupy Documentation (lang=en-US)
Intro
- Calculate home energy usage per day and month
- Estimate energy cost which will be paid monthly
- Help saving energy by knowing estimation
- Calculation is not from live data or history
- Based on maximum possibility
- Accurate prediction is not guaranteed
Base Formula
VA = W
KVA = KW
WHn = W * H
DWH = WH1 + .. + WHn [NEA]
MWH = TWH * 30
MKWH = MWH / 1000
MB = FKWH * P
Additional Formula
DWH < VA
Based on maximum usage & time per day
Possibility : Result - 50 %
Declaration
VA = Volt-ampere (VA)
W = Watt (W)
WHn = Watt of n / Hour (Wh) [Limited to 24]
DWH = Daily Watt / Hour (Wh) [Limited to VA]
MWH = Monthly Watt / Hour (Wh)
MKWH = Monthly KiloWatt / Hour (kWh)
MC = Monthly Cost (Rp)
Usage | Monthly | Tax
>= 6600 VA = Non-Subsidy = Rp 1.000 / kWh
< 6600 VA = Subsidy = Rp 600 / kWh
TP = 5 % = 0.05
Input Example
[Separator I]
[Title]
[Separator II]
- Name : Person
- Household Power (VA) : 2200
- Number of electronic appliances : 3 [NEA]
Electronic appliances list :
EA 1 | Power (Watt) = 10
- | Usage (Hour) = 1 [Limited to 24]
- 2 | Power (Watt) = 20
- | Usage (Hour) = 2
- 3 | Power (Watt) = 30
- | Usage (Hour) = 3
Process Example
WH1 = 10 * 1 = 10
WH2 = 20 * 2 = 40
WH3 = 30 * 3 = 90
DWH = 10 + 40 + 90 = 140
MWH = 140 * 30 = 4200
MKWH = 4200 / 1000 = 4.2
MB = 4.2 * 600 = 2520
Output Example
[Separator II]
Your name = Person
Household power = 2200 VA
Electronic 1 Watt = 10 Wh
Electronic 2 Watt = 40 Wh
Electronic 3 Watt = 90 Wh
Daily Watt Hour = 140 Wh
Monthly Watt Hour = 4200 Wh
Monthly kWh = 4.2 kWh
Monthly Price/kWh = Rp 600
Monthly Bills = Rp 2520
[Separator I]
Future Formula
I = V / R
V = I * R
P = I^2 * R
P = V^2 / R
W = I^2 * R * t
W = (V^2 * t) / R
W = P * t
TAX = MP + (MP * TP)
Future Features
- Naming each electronic appliance item.
- Using future formula
- Specific tax by place & location
- Pluggable Authentication Module (PAM)
