The Controllers will be sold via our retailers. Please PM if you were to look for your closest retailer.
So I send them a PM one week ago, they did not read it.

Re: Mobipus Controllers

Mobipus is still a new company and for more than a year they didn't answer to anybody, even their distributors. This could happen again or they can go out of business in a few years, and that's why repairability outside from the manufacturer is important. Even if their controllers are better than th...

Re: Mobipus Controllers

Here are the differnet parameters for each level, from the documentation I took from SamD website a few months ago. In the files there was also a TeamViewer installer, why do they want to take remote control of the PC running the software ? access_level.PNG The asterisk is not defined in the spec bu...

Re: ATV conversion (mostly done)

No idea about wildlife, there isn't much around here (or I don't see them), but the MTB riders/hikers appreciate it !

The power above 10km/h is great but not under, it is difficult or even sometimes impossible to start uphill, I don't know why.
There must be some parameters to change but which ?

Re: ATV conversion (mostly done)

Sorry for the very very late answer, it costed about 4000€ It is now almost finished, I still have to tweak the controller to have more power at startup but that's all. Maybe create different drive profiles as I have a switch wired but is is not really necessary. The issue I had with the regen not w...

Re: ATV conversion (mostly done)

Thanks !

Yes I expected that for LiFePO4, but it's fine I won't use it a lot and almost never in winter because I will also be cold !

I have no idea for the range but 50km would be nice to have, I expect it to vary a lot depending on the terrain.

Re: ATV conversion (mostly done)

The things to finish are mostly around the Sevcon programming: - figure out how to have regen on throttle release - add a brake lever for variable regen, I will use an hydraulic one with a pressure sensor - eventually setup the 3 different profiles with different power / regen levels - find how to l...

If you don't already have a tool to sniff the CAN communications here is one I used. It is cheap, open source and works really well (tested on a car): http://www.fischl.de/usbtin I don't know much about CANOpen but here are some informations https://stackoverflow.com/questions/1232624/how-to-program...

They are not perfectly waterproof, the Peugeot E-Vivacity scooters (they use size 2) have issues when used/parked under rain: http://www.vehiculeselectriques.fr/post222721.html#p222721 (in french) But they made a bad design choice, some water goes directly on the connectors. http://fs5.directupload....

Re: Adventures in programming a Sevcon Gen4 Size4

Hi, I am highly interested because I also have to program almost the same motor (ME1115 with regular hall sensor instead of the stock sin/cos), I will start in about 2 weeks. I already made a few tests on a bench a long time ago, got the motor running with no load but the amperage was much higher (m...

Re: Mobipus Controllers

Thanks for your answers Shenta.

Is the PowerLock pin used to pre charge the capacitors before to close the contactor ?
The AUX output can't provide power to the contactor but what is its voltage level ?

What motor characteristics do we have to enter ?

Re: Mobipus Controllers

What is the continuous and peak power capability of the 72200, and what is the phase current limit ? If 200A is the battery current it means 72V*200A = 14kW, but for how long with a good cooling ? EDIT: from http://www.mobipus.com/mc-p4.html it seems that it is 100A continuous and 200A peak Is it po...

Re: Sevcon GEN4 72-80v 350A : 400$

Because the DVT software from Sevcon is implemented to use a specific model that provides software APIs.

It is of course possible to communicate with any CAN interface, but then you will have to program the hundreds of registers by hand... good luck !

Re: Sevcon GEN4 72-80v 350A : 400$

I have also bought him a controller but have a motor with sin/cos sensor, I think it is the same as in the Zero: ME1114.

I am in contact with motenergy and I am pretty sure he will find a solution to put an UVW sensor... well hopefully !

What do you mean by half HD resolution ? What is the minimum android version ?

I could test it but only in a bench for now (until april I think), so I don't know if it can be usefull for you.

Re: foundingpower programmable bms

There is an Allegro sensor on the PCB for the charge measurment and an unknown brand that goes around the battery cable.
This one can be replaced by any model that have a 5v supply and and 2.5v output at 0A. LEM makes very good sensors up to 20000A, for example this one for your need.
