Exciting news guys....
A member approached me the other day and we got to talking. He runs a Machine Shop and has the capabilities to manufacture a heat sink housing for the HVC Breaker module. This has several implications...
1) We will now be able to run 60A+ continuous
2) The module can now be fully potted in epoxy
So this means that we can re-purpose the HVC breaker to be an LVC Breaker.
You will be able to wire this fully potted module between your battery and controller
If any one cell hits 3.0V it will latch up and stop all discharge on your battery
Voltage range is about 30V to 130V... but that can be extended in either direction pretty easy
We are currently feverishly working on this. It should be plug and play with all of the existing systems out there... just unplug your retard cable and plug this in. OR -> Use both for redundancy.
I was only able to test up to 50A continous here before my testing rig melted down
I am going to pick up a huge constant current supply from Liveforphysics to do some 100V 100A testing. Anyway...
Since I am blabbing -
We secured a load of the new motors from Croatia - so expect to see those on our website.
It is looking like we are going to stock 18fet, 24fet, and 36fet controllers. These will be serious controllers for men and women who are out of control.
PS: Some people might suggest that the LVC Breaker module only temporarily cut power and then resume... Like the throttle retard does. I dont think this is the right way to do it for many reasons. First of all... if a single cell actually hits 3.0V under load on the average ebike you are done. Yea - you could milk it down... but that is just stupid. The way to do it is to set pack level LVC a bit higher and slowly glide down on that smooth power decay ramp. IF any one cell blips 3.0V before your smooth pack level LVC starts to kick in that is a sign of an imballanced pack and it is time to stop. Just think about the sum of the cells and visualize it... So for now this is how we are going to implement the system. I will consider releasing the instructions for how to mod the system to be a temporary cut out...(like the retard cable) the board has an RC delay built into it that I normally do not populate (I just have the breaker latch up and de-power itself) but for those who are adventurous I will show you how to play.
(and then sell you more when you blow it up
It is basically just a large ceramic capacitor on the gate of the mosfets that is inline with a 100K resistor so once the system "trips" it takes some time for that cap to charge back up to turn the mosfets back on. It basically adds some hysteresis to the system so that it does not shutter when not latching.
