I wonder,is it possible to send power down to the bluerov2 to continuously charge the battery (Lithium-ion Battery (14.8V, 18Ah)
as you can do with laptop?
I have look at Deep Trekker,they have a Hybrid-Power System,to send power to the ROV’s
internal batteries to continuously charge the unit while it is plugged in.
I use a seabotix cabel (8.9mm) it has 6 shielded wires,two of them is 17AWG,the rest is 24AWG.
Do QGroundControl or software need to be modify to continuously charge the battery?
Can you use a Battery protection board with Balance and connect power to it,to continuously charge the Lithium-ion Battery?
Very good idea to have two sets of batteries and changeover circuit,but then you need to have exstra enclosure and the Payload Skid.(the BlueROV2 will be much higher and heavy,i like the height and weight as it is now)
What output voltage,should be to charged the battery?
Isolated DC/DC converter I’ve found has only 60W (4Amp) i can use three of them (12Amp)
These Isolated DC/DC converter is very expensive,but best quality.
Isolated DC/DC converter can not be bigger,it is very small place in the battery Enclosure,but it is enough space for 3-4 60W.
Can you trust on this BMS printed circuit board? was very cheap.
Does this have any impact on the QGroundControl or software to Bluerov2? (Voltage measurement,Amp measurement,Safety settings)
Everything works,but the battery charges only with 2 amp.(measured with a ammeter)
I do not know why, (when i try the system,the battery was 15.3 volts when i connected the charger to battery,after 4-5 hours the battery was full 16.8 volt) bluerov2 was ON.
The DC/DC converter i use is Traco Power TEN 60-4813WIN i use two in parallel,will give out 6.5 amp/16.8 volt.
The BMS Board with balance have max working current 30 Amp.
@an-ron you said bluerov2 was on so what was the power consumption of rov when you were charging? As i know bluerov2 works over 40A when %75-%100 gain mode on, your BMS board can not handle with it. Have u checked any other BMS which fits the tube?
you said bluerov2 was on so what was the power consumption of rov when you were charging?
I had only bluerov2 on,sow it was only 0.90 amp without the light and Thruster.
If you use the bluerov2 at 25 -%100 gain mode always or light on without a break,the battery will not charging, because the battery is only charging at 1.8 Amp.
The BMS board can handle 30Amp you don’t need any bigger,because the battery 18Ah can only be charging at 10-15 Amp
Have not figured out why the battery only charging at 1.8 Amp,should have charging at 6-7Amp need to measure a little more.
Does the BMS handle 30A charge or 30A discharge? A BMS that could handle 30A charge would be pretty substantial. That’s a lot of current. Handling 30A discharge and a few amps charge is more likely I think.
