That's awesome! Well done.

I'm working on a project that's similar to this. I have an 850W computer PSU as well as a 48V PSU. the 48V will be used for a DROK regulator like yours, and the computer PSU will just be for +12, +5, and +3.3.

u/thejavacoder16 · 2 pointsr/ebikes

You need a voltage regulator that outputs a relatively constant 18v even when the input voltage ranges from 40-54v.

Something like this

I would be extremely careful with something like that though, because one little slip up and you could be sending 50v to your laptop most certainly killing the motherboard.

A solution that is safer for your laptop but way less efficient would be to use an inverter to create a 120v source that your laptop charger can use to safely output 18v.

The ideal solution would be to have a board that is dedicated to converting a variable high voltage to 18v and has over/under voltage and current protection.

No adversarial intentions: note that you are wasting a lot of efficiency in the unnecessary DC to AC to DC conversion, and you are carrying around extra circuitry and extra heat sink weight. You'd be a lot better off if you just carried a battery of similar voltage to what the adapter outputs. Some tinkering required.

UPDATE: here's some update to counter the criticism.

  1. The original brick that Boosted sells you is not just a transformer + rectifier, it's a two-phase charger from a manufacturer called Mean Well. It uses a standard two-phase charge method: first constant current, then constant voltage. https://www.mouser.com/datasheet/2/260/GC120-SPEC-1292126.pdf
  2. There is a manufacturer of battery-powered landscaping tools called EGO that uses battery packs at 56 volts. Even Home Depot carries them. They make battery packs in different capacities ranging from 2Ah to 10Ah, and they even make a huge backpack with 28Ah.https://egopowerplus.com/power-batteries-chargers/ https://egopowerplus.com/battery-7-5amp/https://egopowerplus.com/commercial-backpack-battery/ This is all stuff you can buy off the shelf.

    You can't connect the EGO battery pack into the Rev input connector because if the battery is low enough, the voltage difference will cause an excessive initial current inrush and (at the very least!) damage the Rev battery. Ideally you need a DC-DC Li-ion Charger that implements the same phases as the Mean Well. There's none available on the market, and I checked really really well, but you don't have to despair.

    You can regulate the charge process BY HAND. I've done it in the past. I've even revived dead sealed lead-acid batteries using a laboratory power supply. There's plenty of them. Any of them would work in your case, but they all take home AC as input. You want a DC input one. The solution is:

  1. use a DC-DC buck regulator like this one: https://www.amazon.com/DROK-Adjustable-Regulator-Stabilizer-Transformer/dp/B0744BT79M
    or even better, this one: https://www.amazon.com/Converter-DROK-Regulator-Constant-Adjustable/dp/B01MSJQAKY

    The buck converter is really easy to use: it has buttons to set mode (constant current or constant voltage) and up-down buttons to set what limit.

    USAGE: you want to limit the initial current to 1/2C; the internal Rev battery should have a C of 8.5A approx; so you want to stay safe and limit initial current to 4A. You set 4A in the display as current limit, and you let the charge ramp up. In the meanwhile you observe the voltage increase. As the Rev battery will charge, current will decrease. Now you need to limit voltage to make sure you don't overcharger. Set an appropriate limit to the DC-DC converter and you are done.
