Camper electric hookup demand calculator

Calculate peak coincident power and total energy with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use peak coincident power and total energy to compare changes to your inputs. The method and limits below explain the scope.

Examples

Examples

Try the starting example

Appliance schedules JSON [[start hour,end hour,power W],...]
[[0,2,1500],[1,3,800],[3,5,500]]
Supplied hookup power limit (W)
2000
Peak coincident power (W)
2300
Total energy (kWh)
5.6
Over-limit intervals [start,end,power]
[[1,2,2300]]

Calculation method

Calculation method

Peak coincident power (W)

Sum active power over each half-open time segment and integrate load.

Total energy (kWh)

Sum active power over each half-open time segment and integrate load.

Over-limit intervals [start,end,power]

Sum active power over each half-open time segment and integrate load.

Symbols and units

Appliance schedules JSON [[start hour,end hour,power W],...]
b
Supplied hookup power limit (W)

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • User supplies hookup limit; no wiring, current phase or breaker adequacy calculation. Supported limits: All required fields must be finite values of the exact declared type and within displayed bounds. Lists contain1–1000 finite numbers. JSON tables are numeric rectangular rows, at most100 rows and30 columns; individual tools have stricter shape/domain constraints. User supplies hookup limit; no wiring, current phase or breaker adequacy calculation.
Are these inputs private?

These calculations run in your browser. A shared link contains the values you choose to share. Only questions submitted to the separate AI finder are sent to OpenAI.
