Description
Kit (Battery) is used to create stationary battery cells, which can provide big and stable energy storage or energy buffer for your power needs. Its energy storage is 3.6MJ or 1kWh.
Power Leakage
All stationary batteries slowly loses stored energy. Batteries in an environment at or below the Armstrong Limit (6.3 kPa), including a vacuum, drain at 50W regardless of temperature. Batteries above Armstrong Limit drain at between 50W and 10W, depending on pressure and temperature. The drain factor is computed as:
MAX(10W, 50W * [1 - ( T / 273.15 ) ] * MAX( P / 101.325 , 1 ) )
Where P is the ambient pressure in kPa, and T is the ambient temperature in Kelvin. Any battery at least 1 atmosphere (101.325 kPa) of pressure that is at at least 0°C will drain the minimum 10W, with the drain increasing as pressure and temperature drops. Note that since the calculations use a min, rather than multiplying against the extra 40W, the total muliplier only needs to reach 0.8 rather than 1.0 to minimize drain. For example, a battery at 0°C and 0.8 atmospheres (~81 kPa) of pressure will still have the minimum drain, as would a battery at 1 atmosphere of pressure and -54°C.
Because of an error in the formula, low pressure can allow lower temperatures to be used, so long as the battery is kept above the Armstrong limit. For example, at 0.5 atmospheres (~50.662 kPa), the temperature must be at least -109.26°C to minimize drain. By comparison, setting the pressure to 150 kPa (~1.5 atmospheres) would increase the required temperature to as high as -54°C. Note, however, that pressures above 1 atmosphere do not provide a change in power leakage characteristics relative to 1 atmosphere.
The power drained this way is converted 1:1 into ambient heat in the surrounding environment, provided the surrounding environment is above the Armstrong Limit. Over time, this requires some form of cooling to avoid the environment getting too hot, unless the batteries are simply left exposed to external atmosphere.
On particularly hot worlds, where cooling is difficult and more involved, it may be more efficient to store batteries in a vacuum (which entirely removes the heat output, at the cost of maximizing the battery drain rate), or simply in the exterior atmosphere (which also removes the heat concern, and on hot worlds, will usually minimize battery drain even at low atmospheric pressures. Batteries fortunately do not take damage from storms). On especially cold worlds, placing the batteries in a pressurized room can largely offset any losses from temperature, and thermally connecting the room to the outside (using radiators, or potentially even simply as placing an uninsulated pipe containing gas through a wall) can offset the heat output from the batteries as they drain.
Usage
A battery's power throughput is only limited by the power demanded and supplied, meaning it can take any amount of power and supply any amount of power. As such, batteries can easily exceed the ratings of even super-heavy cables. Due to their unlimited throughput, connecting a battery's output to a battery's input (its own, or another) will act like a short circuit, immediately burning out the cable network.
Additionally, it is advised to follow these rules:
- Never connect the output of one battery to the input of another battery without a Transformer in between!
- Never connect the input and output networks of a battery together.
- To build batteries on downstream networks, ensure Transformers are used to limit the power transferred between the batteries.
- Also note that Transformers apply a 10W drain to their input network in addition to the maximum draw they are set to, so the transformer may need to be set slightly lower than its maximum to avoid burning out the network. For example, two Large Transformers in parallel set to 50 kW will apply a maximum draw on their input of 100.02 kW, which will burn out the input network if it is heavy cable.
- Rather than chaining battery-containing networks one after another, a safer configuration is using a branching setup, where all downstream networks draw in parallel from the output of all of the batteries. Placing transformers between the batteries and the downstream networks can also help prevent circuit overload.
- Always separate electrical networks with power generation (solid generators, solar panels, etc.) from networks with power consumers. A common layout has all generators on the input network for the batteries, and all consumers, possibly in separate downstream networks, attached to the output from the batteries. No generators should be attached to the battery output, and no consumers (except for possibly some logic devices) should be present on the battery input network.
- Never connect a fueled generator (Solid, Gas, Stirling, or otherwise) or a Wind Turbine to a battery using standard cables - only use heavy or super-heavy cables. A battery will consume as much power as the generator can produce, and all fueled generators (except the Portable Generator) can generate more than 5 kW of power. Wind Turbines naturally generate much lower power than a standard cable can support, but during storms, this output can increase far beyond the capacity of a standard cable.
- When making major changes to a power network (especially a very sprawling one), it is recommended to de-power the network by turning off batteries, transformers, and APCs (or simply cut the associated cables) to avoid accidental network interconnects and the resulting cable burnouts.
Data Network Properties
These are all Data Network properties of this device.
Mode Values
This shows the values of the "Mode" property, mapped to what the display will show.
| Value | Display |
|---|---|

Data Parameters
These are all parameters that can be written with a Logic Writer, Batch Writer, or Integrated Circuit (IC10).
| Parameter Name | Data Type | Description |
|---|---|---|
| Mode | Integer | Expects values 0-6. Setting this, will let the charge display of the Battery show the according charge value for about a second. Afterwards it will switch back to showing the actual charge value. This influences the "Mode" output as well. (See Mode Values.) |
| Lock | Boolean | Locks the Battery, when set to 1. Unlocks it, when set to 0. |
| On | Boolean | Turns the Battery on, when set to 1. Turns it off, when set to 0. |
Data Outputs
These are all parameters, that can be read with a Logic Reader or a Slot Reader. The outputs are listed in the order a Logic Reader's "VAR" setting cycles through them.
| Output Name | Data Type | Description |

| Charge | Integer | Returns the current charge of the Battery in watt*tic. |
| Maximum | Integer | Returns the maximum charge of the Battery in watt*tic. |
| Ratio | Float | Returns a range from 0.0 to 1.0. Returns the current charge percentage of the battery. |
| PowerPotential | Integer | Returns the current power potential at the input of the Battery in watts. |
| PowerActual | Integer | Returns the amount of power, currently being output by the Battery in watts. |
