# Electric System Setup Information<no value>
On this page you can find additional information and parameters that are used when setting up the [Electrical Systems](../modular-electrical-system-information/) for an aircraft.


### Numeric Inputs

Previous iterations of electrical systems in FSX and Microsoft Flight Simulator 2020 used either a *curve* or a *value* as part of the input, and if you used a curve then it would be automatically interpolated based on the component properties (APU, engine generator, battery voltage, etc...). However this led to a certain inflexibility in the setup of the electrics, and as such the current system has removed these hard-coded dependencies as much as possible, meaning that any numeric input is now either a *parameter constant* or a *curve*.

The two types of parameter constants that can be used as numeric input are as follows:

-   **SimVars**: For example you can use the following to get the first engine RPM.

    ``` cpp
    [data.simvar(GENERAL ENG RPM:1, rpm)]
    ```

-   **Global Variables**: For example the following gets the global (user created) variable `GLOBAL_VAR` as a boolean.

    ``` cpp
    [data.globalvar(GLOBAL_VAR, bool)]
    ```

Here is a full example setting up a [Generator](../modular-electrical-system-information/#generatorn) where a constant parameter is being used, the SimVar [`GENERAL ENG PCT MAX RPM`](../../../../programming-apis/simvars/aircraft-simvars/aircraft-engine-variables/#GENERAL-ENG-PCT-MAX-RPM), along with a curve:

``` cpp
generator.1 = Name:LH_ACGenerator # Vrms:115 # PowerRating:90 # GovernedRPM:[data.simvar(GENERAL ENG RPM:1, rpm)] #ReferenceRPM:2000 #ReferenceFrequency:400
```

These different types of parameter constant can be used directly as an input for any hash-map parameter in any component in the electrical system.

It is worth noting that for curves you can supply an additional value to re-map the curve that has been given to be within a different range. The supplied value should be enclosed in `()` after the curve path, for example:

``` cpp
/* A curve */
curve.1 = Name:MyCurve #Points: 100:0, 500:27, 800:28
/* Using that curve to remap the aircraft ram air RPM to a voltage */
supplier.1 = (...) GovernedRPM:[curve.MyCurve([data.simvar(GENERAL ENG RPM:1, rpm)])]
```

If you are unsure what value to use then simply supply a 1 so no re-mapping is applied.

Finally, some commonly used real life values are exposed for your use as parameters, such as the chemical voltage of a cell given its current capacity for different compositions, eg: Lithium-Ion, NiCad, etc... You can find these built-in values from the links below:

-   [Cell Types](#cell-types)
-   [Trip Curves](#trip-curves)


### Consumers/Suppliers And Inline Setup

It is important to be aware of the fact that all [Supplier](../modular-electrical-system-information/#suppliern) and [Consumer](../modular-electrical-system-information/#consumern) data should be in **one** place, ie: it can be in *either* a supplier, *or* a consumer, but not in *both*. If a supplier/consumer is given to a component as part of the component definition, then all other supplier/consumer parameters given directly in the item definition will be ignored. Essentially, supplier/consumer configurations have priority over "inline" configurations.

Consider the following consumer and circuit definitions:

``` cpp
consumer.6 = Name:ConsumerStarter #Voltage:24 #Wattage:3500
consumer.7 = Name:ConsumerFuelPump #Voltage:24 #Amperage:2
circuit.4 = Type:CIRCUIT_STARTER #ConsumerCfg:ConsumerStarter #Name:StarterB
circuit.5 = Type:CIRCUIT_PITOT_HEAT #Voltage:12 #Wattage:40 #Name:PitotHeat
circuit.6 = Type:CIRCUIT_FUEL_PUMP #ConsumerCfg:ConsumerFuelPump #Wattage:48 #Name:FuelPumpA #WearAndTearCollision:GlobalDamage
```

In the example above, circuits 4 and 5 are valid, but in circuit 6, the wattage will be ignored because a consumer configuration has already been given, and so the information from the consumer will be used.


### Cell Types

The following built-in battery cell types are available for use in the [Supplier](../modular-electrical-system-information/#suppliern) component. These are simply easy to remember parameters that are used instead of hard-coding the underlying [Curve](../modular-electrical-system-information/#curven) values. In the tables below, the values given here for the curves are for a *single* cell of the given battery type.

{{< callout context="note" title="NOTE" icon="outline/bulb" >}}

The C-rate represents the amount of time in which the battery goes from fully charged to empty, 1C means the battery empties in 1 hour. In the simulation, we use curves measured at 0.1 C-rate for the low loads (ie: 10 hours of battery life), and 15 C-rate for the high loads (4 minutes of battery life).

| 90 | 1.22 | 1.1 |
| 100 | 1.3 | 1.15 |

{{< /table-wrapper >}}

    {{< /table-images >}}

You can see how these battery parameters are used in the example below:

``` cpp
supplier.1 = Name:SupplierBatteryA #SType:Battery #BatteryType:NiCd
battery.1 = Name:MAIN_BATTERY #ConsumerCfg:ConsumerBatteryA #SupplierCfg:SupplierBatteryA
```

To compute the output voltage of a battery, the simulation estimates the voltage for *one* cell from **low** and **high** voltage curves, depending on battery *type*. It first determines the C-rate from the load currently drawn from the battery, and then an interpolation is performed to get a voltage value between the low and high load voltage curves. Once the simulation has calculated the voltage of *one* cell, it is multiplied by the number of cells in the battery that was determined from the battery nominal voltage at the time of the aircraft spawning.

With this method, output voltage depends on the state of the battery **charge** and **load**, as well as the [Wear and Tear](../../flight-model/additional-flight-model-information/#note-on-collision-damage--wear-and-tear) amount, ie: more load, more wear, and less remaining capacity, will all result in less voltage output.


### Trip Curves

A trip curve is used to define how much of an overload a [Connection](../modular-electrical-system-information/#connectionn) component can sustain before tripping the [Breaker](../modular-electrical-system-information/#breakern). The overload is based on [IEC](https://webstore.iec.ch/publication/59762 "IEC 60255-1:2022") and [IEEE](https://ieeexplore.ieee.org/document/1588760 "IEEE C37.90-2005") formulas that give a duration before overload for a given load and design load. Within the simulation these have been transferred into built in parameters that you can use, following the format as outlined in the section on [Numeric Inputs](#numeric-inputs). For example:

``` cpp
breaker.1 = Name:A_Breaker # RatedCurrent:5 # TripCurveType:IEC_Vinv
```

The main trip-curves relating to both standards are built into the simulation as easy to remember parameters which can be used where necessary:

### Key Events

The table below shows the different key event IDs that can be used to modify things within the electrical system of an aircraft. These are often used along with the [Aircraft Electrics Variables](../../../../programming-apis/simvars/aircraft-simvars/aircraft-electrics-variables/) to control the electrical systems with the aircraft. For more details on how to use these events, please see here: [Event ID's As Key Events](../../../../programming-apis/key-events/key-events-index/#event-ids-as-key-events).
