In step down mode the inverter simply doesn't know the battery voltage because it can only measure rectified mains voltage on the DC bus. It means you need some external mechanism to stop charging when the battery is full. this hint had its positive effect, thank you so much for your help! now, if ...

ah, there is a different precharge setting because the DC bus is run at a higher voltage than your low voltage battery. The parameter is called "udcswbuck" does this mean that an inverter that does not know how to measure the battery voltage will not be able to use the step-down mode? I u...

you can test it just on the table without connecting a real battery, motor and input high voltage. it is enough to take the v3 board, apply +12 to the main power supply, turn on the "downgrade" charging setting and simultaneously apply +12 to "forward" and "backward", i...

Indeed I haven't used buck mode in a long time. What inverter are you running it on and have you wired it correctly? https://openinverter.org/wiki/Battery_Charging I used boost mode on all my inverters (Honda IMA, Nissan leaf 2) and it works fine even at 75 amps input current!!! This time I have an...

am I really the only one using the ability of the OI board v3 to charge batteries through an inverter-motor?

Any idea on the above? switching to neutral when switching off the sw forward should clearly work immediately, regardless of what the motor speed is (isn't that the case now?) but the reverse gear, when turned on, turns on at speeds below those specified in the value (it seems to work like that, I ...

I have always used boost mode to charge the battery from the mains via a diode bridge. this is a great thing! but now I have a low-voltage battery and I wanted to use the down mode. however, after I supply +12 to the power supply of the inverter and turn it on both forward and backward at the same t...

Tomorrow, the motor will be driven at low voltage to high speeds due to weakening

shouldnt mess with working system

you made a gross mistake and flashed the firmware from the synchronous motor into the asynchronous)) download and update to the firmware marked sine!

I did some research, main capacitor is 700uF 450V and IGBT module is MBB600TV6A, which is 650V 600A. It sounds to me that there could be potential to deliver more than 70kW with good cooling. in the nissan leaf gen 2 inverter, there are also power IGBT modules for 600 volts and 600 amps. at the sam...

Ah Matt, no rumours and myths ;) sources? Prius larger power stage is capable of, optimistically 500A (peak!) and Leaf Gen2 of 1000A. The latter manages 140 kW@360V before it desats. Half the current -> half the power. Unless you run a 600V battery or something. I will add: the Nissan leaf gen2 inv...

been to design a board that will mount on short standoffs over the original pcb and have very short jumpers going to the gate drives, current sensors, and bus voltage feedback. I use Honda ima + brain v3 OI inverters very widely. but I have not yet been able to find a point at which the native inve...

I've always put a brake line switch on the front wheel of my motorcycles. this made it possible to block the front and anneal the rubber by warming up the rear wheel. the simplest and most reasonable solution.

no, if the cruise is turned off, then the behavior of the motor is adequate and the reaction to the gas pedal and the brake pedal is correct. however, this is not exactly a Nissan leaf motor. this is the EM57 motor from Nissan note e-power. I tried to drive yesterday and very often got overcurrent, ...

as for the new changes for the purpose of cruise safety, my personal opinion is that they are redundant. as my experience has shown, it is enough that pressing the brake or turning on the neutral cancels the cruise even if it is pressed with a lock, and it is restarted only after the cruise button i...

I remind you, the purpose of this experience was to check if the cruise button initially stuck in the pressed state at the topikstarter?? that's why I closed my button and performed all the tests, including the controller with the cruise button pressed in advance.

unfortunately I forgot to save them. I'll do it tomorrow

https://youtu.be/_GiqKen3qzY today I conducted an interesting experiment with the 5.27 foc firmware. I submitted a cruise +12 to the entrance and kept it there until the motor started rotating. The behavior of the controller was very interesting! firstly, as soon as I pressed pot1, the motor started...

When transistioning to strong regen at speed field weakening would collapse and cause really strong regen. Does catch itself but still not good. I simply increased vlimmargin from 2000 to 4000 and that fixes it. still, an adequate description of all these parameters would not hurt, then the users (...

did I understand correctly, the controller running the version 3 board was in charging mode and when updating in this state, something went wrong?

I forget to ask if the description of the parameters has been updated? after all, a lot has been added, some have been renamed, and some have disappeared. or maybe it is in some new place?

thank you. now I will sit down to read these topics. yes, that's why I wanted to see the settings file and the connection from one person so that it would work right away.

I mean, there is someone who has already installed this motor in the car and drives driving not a can bus, but an OpenInverter brain.

There is some video of me running outlander rear motor and open inverter Inductance 230uH resistance 180mOhm miscellaneous wiggle range: 90 deg wiggle rate: 180 Hz this is very cool. but that doesn't answer my question. are there people here who drive this motor using any controller controlled by t...

there are so many topics on Mitsubishi, but it turns out to be very difficult to find the information I need. Does anyone use this motor with an open inverter board? share the configuration file if you have it. thank you.
