[WIP] Citroen Saxo Electrique

Bought a Saxo electrique december of 2018 with a burned collector on the dc motor. 20191020_175321.jpg Original: Motor: Leroy-somer SA-13 11kW (20kW max) separately excited dc motor Batteries: SAFT STM 5-100 nickel-cadmium 20x6V 120V nominal Controler: 200A dc with 11A for excitation Charger: 3kW (i...

Re: Volvo V60 ERAD motor

After reading some more on the forum about tuning motor parameters. So i decided to measure the motor parameters: Rs = Resistance of the stator winding flux linkage = BEMF Constant Ld = d-axis inductance of the stator winding Lq = q-axis inductance of the stator winding First Rs this is the simple o...

Re: Temperature sensor

Have looked through the code for the temperature sensors. I think the NTCK45 and the PT1000 are "labeled" wrong in the "static const TEMP_SENSOR sensors[]" The "coeff" for the NTCK45 is NTC. This seems logical but this is wrong in my opinion. with the other sensors if t...

Contactor economizer

Have seen a couple of different solutions to make a contactor coil economizer. The simplest one is the resistor and capacitor in line. For my contactors the resistors will dissipate 6.5W so they need to be big. On the forum I have see someone using a resistor and capacitor in combination with a dcdc...

Re: XC90 inverter teardown and reverse engineering

IT RUN'S !!! 8-) Got the motor running on a 30V 5A power supply. I have the syncofs roughly set. Changed R46 from 10k to 8k2 to lower the excitation signal. When I put the scope on the sin or cos lines the signal oscillated between -0.5V and 3.5V. I don't think that will be great for the FOC softwar...

Re: XC90 inverter teardown and reverse engineering

Yes it drives the power stage. On the power stage board there is a isolated DC-DC converter with multiple outputs to power the IGBT drivers. From memory it outputs +15V en -5V not a 100% sure. I need to take the unit apart to reseal it. when i do i will take a picture of the power stage. The only ph...

Wiki link to Melexis MLX91204 is dead

The link is dead and so is the chip. When i searched for the MLX91204 I got this as a result.

The MLX91204 is no longer available and replaced by the MLX90380

MLX90380 is better as far as I can see. and it works at 3v3

Re: XC90 inverter teardown and reverse engineering

Got the DCDC converter working today :D The DCDC gets a voltage signal from the inverter power board and sends the value on the canbus. the signal is 8.5mV/V and this needs to be above 200V equivalent so 1.7V. The PSRP_WAKEUP signal needs to be 12V. On the canbus you need to send on ID 0x101 with 8 ...

Re: Volvo V60 battery pack

hi,

the 0x16h and 0x1Ah are new to me. will add it to the code. and see if it helps.

i am sending the 0x17, 0x1B, 0x1F and the 0x1C

the 0x1F message two bytes 0xFF and a counter.

the 0x16h and 0x1Ah are not in the log i made from the other complete pack I have.

thanks
