Are you tired of running around with solar panels for a long time until you can unlock those precious portable fusion reactors? Or did you perhaps ever wish you could just charge your power armor from your electricity network?
Then this mod is for you!
Induction Charging adds five tiers of research, from early game to endgame. With the first tier you unlock the Induction Coil recipe, which is the only thing you will need to craft. The coil has 1x1 dimensions but very little throughput on its own. You need to have batteries in your equipment grid for the induction coils to charge; otherwise you will not receive power. From there on out you can just research the next tiers to get improved throughput and efficiency!
Did I mention they also work in vehicle grids (provided you have a mod installed that adds those)? They do! If you combine this mod with the Electric Vehicles mod by Semaphor & leoch, then you can use Induction Coils inside the vehicles equipment grid to power your vehicles! Or, if you only want to charge the equipment grid and not necessarily power the vehicles themselves, then you can just use the Vehicle Grid mod by Optera to get equipment grids on your vehicles! Not to mention that if you ever feel like you need denser energy storage, then you can also throw in the Bigger Batteries mod in there!
Xterminator was kind enough to review my mod! I don't think it's possible for me to embed the video here, but you can follow this link to watch the video: Factorio Mod Spotlight - Induction Charging. Thanks Xterminator!
The research tiers are currently balanced as follows:
|Description||Tier 1||Tier 2||Tier 3||Tier 4||Tier 5|
|Throughput||15 kW||30 kW||60 kW||120 kW||240 kW|
|Usage from grid||150kW||150kW||200kW||300kW||480kW|
Note that in vanilla Factorio, the Fusion Reactor provides a throughput of 750kW / 16 = 47kW per tile.
Since throwing in a few tiny coils left and right at random places is inefficient, it also is in this mod. The coils in your equipment grid will be given a color based on their throughput multiplier. To calculate the multiplier for any given coil, apply the following formula:
|Per adjacent coil||0.05|
|Per adjacent coil that is entirely surrounded by coils||0.12|
Take the sum of the scores you get for the coil, and you have the throughput multiplier for that coil. Multiply (your current technology tier)'s base throughput with the throughput multiplier you just calculated to get the effective throughput. This means it IS possible to get throughput higher than might initially seem possible. On default settings, the maximum is 0.5 + (8 * 0.05) + (8 * 0.12) = 1.86, so almost twice as much throughput as advertised! It's currently balanced so that a 4x4 grid of coils averages exactly 100%; anything more than that will go higher. Note again that the multiplier only affects the 'throughput' metric. Costs will scale up accordingly, and efficiency will stay the same.
Using the mod is as easy as inserting the induction coil into your power armor grid, and you're done! Now, whenever you stand within range of power poles, the induction coils will automatically charge the batteries in your equipment grid. Do note however that it comes at a price! Per the technology tiers table above, we can see that on Tier 1 you will only have 10% efficiency. This means that (at Tier 1) with a single coil you will drain 15kW (base throughput per coil) * 0.5 (coil throughput multiplier) / 10% (efficiency) = 75kW from your power grid, but will only charge your batteries for 75kW * 10% (efficiency) = 7.5kW. The rest is lost to the inefficiency of wireless power transfer.
If you're short on UPS and you'd like to get as much as you can, then you can change the mod settings (
Options > Mods > Map > Induction Charging) to update less frequently. Here you can change either
Update every ... ticks or
Update GUI every ... updates. The former can be increased to 30 or even 60 without too much of a noticable impact. However, if you are actually short on UPS, then I recommend you increase the GUI update setting to a higher value. Updating the GUI is (somehow) the most expensive operation, whereas the regular mod update should be virtually unnoticable in your UPS.
Several balancing considerations have been made when it comes to this mod. There are currently three gameplay related settings that can be changed from within the game. I strongly believe the mod is balanced as-is, and therefore do not recommend you change these settings unless you know what you're doing. If you feel that this mod isn't as overpowered as it should be, or you think it is too overpowered, then you can change the coil score calculation numbers mentioned earlier under
Efficiency in the options menu:
Options > Mods > Map > Induction Charging.

I'd love to hear your feedback! If you have some, or you would like to see a new functionality added, then please use the discussion page! I'm looking forward to reading what your thoughts are.
The following people can be found on the Factorio Discord server.
First, hats off to the amazing person by the name of IronCartographer. He's contibuted tons and tons to the development of this mod, from bringing ideas to the table, to balancing or helping me debug it. Be sure to thank him when you see him around!
Then, a big shoutout to the awesome people who helped me a lot with modding:
- Bilka - Helpful Wiki Admin
- Gangsir - Head Wiki Admin
And last but not least the people who helped me here and there with small contributions:
Let me know if I forgot you!
|1.5.14||Removed forgotten debug message.|
|1.5.13||Fixed crash when interacting with equipment grids per 0.16.40 update.|
|1.5.12||Fixed technology research effects not being displayed.|
|1.5.11||Fixed incompatability from 0.16.25 onwards related to incorrect player detection.|
|1.5.10||Fixed incomplete validity check before deleting old GUI during model migrations.|
|1.5.9||Fixed crash when placing any vehicle.|
|1.5.8||Minor locale changes to be clearer and more in line with the mod description page.|
|1.5.7||Updated for 0.16 and fixed GUI not hiding when un-equipping power armor.|
|1.5.6||Fixed accidental dependency on Bob's mods.|
|1.5.5||Fixed incompatability with different types of equipment grids. You should now be able to place induction coils in vehicles added by Bob's mods.|
|1.5.4||Extended the changes of v1.5.3 to also apply to vehicles being driven by players.|
|1.5.3||Added automatic disabling of charging whilst the user has any form of power pole selected in order to prevent Factorio from having glitchy behaviour when placing rows of power poles.|
