Hacking RYOBI 40V 3-Port charger into a Powerstation
Рет қаралды 23,311
Күн бұрынI've made a bunch of different powerstations based on RYOBI batteries. This project uses the RYOBI 40V 3 -Port charger to make a configurable Powerstation using off-the-shelf components. The powerstation can still charge the batteries, but can be used to run 300/600/1500W Inverters and 30A 13.8DC devices if the power goes out.
It uses blocking diodes so the 40V batteries can be hot swapped and they don't have to have the same charge level (it is always better to have all the batteries at the same charge level). The design is scalable for longer run times or larger inverters. You can use multiple chargers if you own more than one.

Using 0hm's law...4 amps X 3 = 12 amps X 40 = 480 Watts, which is...480 ÷ 12 = 40 ah. So, 480 Watts and/or 40 ah. So 1000 Watts of power drain plus around 20% inverter losses = 56 Watts so 480 Watts - 56 Watts = 424 Watts would deplete those batteries in around 25.5 minutes, of course less with a 1500 Watt inverter but still; not too shabby at all. Great hack Chris 👍

How to make this into something portable. I want to use it for a Sailboat. Bringing the 40volts to the boat electrical panel. Then the inverter and drop to 12 volts. But the charger needs to be able to go back home to charge. I am thinking of connectorizing somehow the 40 volts combines atht e load side of the diodes. So i would need to somehow mount the diode heatsink block onto the Ryobi charger and have a plug of somesort. Thus is could do double duty - bring it to the boat and plug into the panel OR bring it anywhere and plug into other options. Maybe mounting n inverter on teh ryobi case?

Fantastic work and great documentation! I am currently building out a chargeable/hot swappable version of this for a small camping power station this summer. I had a few questions about the diodes you used. 1 - Did you worry about a short being introduced by two diodes sharing a conductive heat sink? I didn't see any insulation that would prevent this but I know very little about these stud style diodes. 2 - Can I use something else that functions as a high powered diode? Specifically I am looking at the 70HF120 Rectifier Diode since it's much lower cost but I am worried about it being a functional sub. Do you think this would work? @SerendipitySue

Right now I am making one of your dual Ryobi 18 volt battery powered Ryobi power inverters, 300 watt, that would normally use a 40 volt battery. I am using a gutted Ryobi 40 volt battery, with just the board remaining, so I have the contacts all ready to slide into the inverter. I will put the two halves of the battery housing back together for more of a stock look. Is there anything I need to look out for? Thanks

@mikenkaried4543 2 жыл бұрын
Would you mind explaining the reason for the diodes? I was thinking it would be a good idea that all 40v connected batteries share the load allowing for parallel sharing (diodes prevent bidirectional current, so remove those), meaning without diodes if one battery is lower than another the higher charged battery will help balance each other and the end resulting capacity of all batteries allowing you to hot swap easier? add a 6ah battery to a 1.5 and the all batteries die at the same time without the diodes.
@SerendipitySue 2 жыл бұрын
Ideally all three batteries have the same voltage and will equally contribute to the load. The reason for the diodes is that if the voltages aren't equal, you can easily make an arc welder! A large amount of current (as much as battery can provide) will rush from the full battery to the empty battery. The result would not be good. Unfortunately I don't know of an inexpensive device that will let the current flow in the reverse direction at 2-3A (which is the normal charging current)
@mikenkaried4543 2 жыл бұрын
@@SerendipitySue A solenoid or relay is cheap and will do what you want.. but I don't think it's necessary, here are my thoughts and I look forward to yours as well on this... the concern if I understand it is the battery seems to have the ability to dump its charge very fast" first off these batteries have PCB boards with MOSFETs that try to force 40v at all times even when the battery is max full or nearly empty. Current can only go up if the voltages are X percent higher than the destination... like flowing water depends on how far you tilt the glass, sure these likely have 12-16x 18650s in them which could means 3 amps per cell, but the key here is a battery can only ingest current at the rate of its chemistry which would limit how fast the current flows into itself out of any of the battery or plural from the "pool" these batteries I believe are rated a 1c max and that makes your wire size engineered at just over that max at 12gauge per battery into a 8-10 gauge bus bar for three of these. Just like how far to tilt the glass with liquid the flow rate will merge from all three or just two depending on the voltage. If one battery is 43 and the other is 38, then technically only 41 volts will flow into the lesser filled battery which will fill or charge very slowly because 41 as not far off from its Nominal when controlled by its built in PCB again to help preserve the tool its plugged into.

I suppose it will need to be checked for space. will the diodes get too hot or cause other problems?

To make it a portable power station like the other one you made though it needs some packaging for the external diodes etc. My thinking was if the diodes were internal then it could be a 40Volt supplu then the other bits would be easier to mount. Problem of course is that the negatives on the diodes would be at +40V if left naked. Thanks so much for every video you do! Dara

RYOBI batteries have the BMS (battery management system) built in. It protects the battery from overcharging, over discharging, overcurrent, over/under temp. I don't know about other brands of batteries. On RYOBI there are four terminals. For discharging you only need the +/-. Charging requires the T1/T2 sensors.

Are the blocking diodes necessary? I’ve connected two ryobi 40v batteries in parallel and their 18v batteries together in parallel for different projects and I could never get any current to pass from one battery into the other. I’m guessing it’s because the internal bms won’t allow voltage to pass through unless the battery is connected to the charger. Which I guess kinda answers my own question. I always used 3D printer adapters that slide onto the battery and have a positive and negative leads coming off, for my projects. However I’d have to remove the battery and place it on the charger every time it died, vs your setup where the the discharge is built into the charger. So of course you need blocking diodes
