Ev mode audible sound, how to stop the beep.

Hi all,

I have got a plug in supply phev kit, and I live in the uk. As the software on the kit is written for the American market, I'm assuming our speeds are alittle different, ie, the phev kit always wants to enter ev mode automatically below or at 30mph, and the kit does do this, but our 30 mph speed must be different to the usa, as the kit tries to enter ev mode when I'm doing speeds of over 30mph even up to 35 mph, the the cars software stops this from happening and the audible alarm sounds, 4 beeps, and words on the led state ev mode not allowed because we are of course going too fast.
This is of course quite annoying sometimes when the kit is constantly trying to get into ev mode and alarms are frequent at speeds between 30 and 35 mph, over this speed the kit stops trying to go into ev mode.
The kit is working really well to be honest, and I am very pleased with the way it works.

One thing I would like to do is to try to stop the audible alarm when the ev mode is not allowed, is there a way of disabling the cannot enter ev mode chime / beep alarm with software, I do own a techstream light.

I wish the PIS program and software was open source, I could alter the parameter myself then.

Been as I am asking for advice may as well ask another question,
One more slight thing that could be addressed is sometimes, but not very often, when I am driving in mixed or blended mode, the oem hybrid battery gets too full of charge and the engine starts to burn off the Excess charge in the battery, again if the PIS program was open source, I could adjust the point at which the kit battery adds into the oem battery, I would drop that parameter a volt or 2 to stop the oem battery going into excess and burn off process.

I must say though, apart from these 2 slight annoyances, the kit is awesome.

Any help greatly appreciated.

 

Don't know to be honest......

Not sure if your miles measurement is different, can't see it though

Or,

The prius ev mode set for the U.S. market must be set higher than the uk market.

In the uk, we cannot enter ev mode at speeds higher than 30 mph...
Out of interest, what is the max speed allowable in ev mode in the states?

Or the software on the PIS control board is programmed to ask for ev mode as speeds up to 35 mph, can't see that either as the " unable to enter ev mode at this time" bleep is really annoying when it's occuring every few seconds as the kit is requesting ev mode when I am travelling to fast for the cars ecu to allow it.

Any ideas.... Thanks

Just for your information some small performance figures from the kit that were done recently

Kit comprises of 76 33ah cells, each cell is made up of 11 26650 ev batteries in parallel, I have a few weak cells that are not that far from the rest so haven't bothered to change these yet, but I am monitoring them. I do have spare cells.

Batteries are charged to 3.45v and discharged to 2.8v

The kit has a range in full electric mode of approximately 20 miles in moderate climate and I live in quite a hilly area.

The pack takes approx 5.5 kwh in electric charge measured with a kilowatt type meter.

About 90% of my driving is all local driving on urban roads where speeds don't exceed 40mph and are generally 30mph

In the uk fuel is approx £6 per gallon or $10 per gallon.

My last £20 of fuel (3.3 gallons) I managed to travel 890 miles, which is awesome, that's why I am very pleased with the kit and the way the car works, it's not perfect, but it will fill the gap until a true ev becomes much more affordable here in the uk.

Hi john,

It sounds as if you have already tried the things I am trying to achieve without success, damn shame that.

I can travel faster of course in oog mode, and I do quite regularly, as most of my mileage is local, low speed, and well within my ev range, but when in blended the bleep is annoying from the kit trying to enter ev when too fast is annoying.

John, is there anyone out there that has the knowledge for us to try to alter some setting in our prius ecu to maybe up the ev speed limit like the usa speed settin, that would be very useful indeed.

 

Hi bisco,

The car ecu in the uk stops ev mode if green bars all full ( which don't make sense to me that we can't use electric energy when the battery is full)
Also the car ecu stops ev mode if travelling faster than 31 mph as britprius has also confirmed.

I haven't spoken to,robb about this particular query, I have found him very helpful, but I did ask him before abouth the program and it is not available to customers to modify themselves.
I maybe could return it to the States and ask him to do a bespoke setting for us in the uk, maybe it's something I could consider, but would not be comfortable sending my pcb across the pond and risk it getting lost or damaged. I have to weigh up the risks and balance thing out.

I may fire an email off to him anyway and see what he suggests.

Thanks for the replies guys.
Anthony

 

Totally agree John, it's not worth the risk of damaging our ecu,s to do that, the risks far outweigh the benefit,

The alarm in question, where is it located and has it other functions, can it be got at easily...

can the alarm be physically disconnected... If it's only the ev alarm, I wouldn't mind just unplugging it, if it could be done of course.

 

I suppose nothing is ever simple these days when working on cars, mores the pity

 

Hi john, tried that link the video no longer exists buddy, checked all the videos on YouTube by luscious garage but couldn't find it, did see another video showing the cm module, but not how it gets fitted with dash removal, looks potchy though

 

Thanks John got it now, cheers

 

Hi mj,

I haven't got a scan gauge but have got paid torque app, plus i also have a techstream.

I have read a few threads which relate to the monitoring of spoofed and real soc, could you please try to explain in detail how I could monitor both of those readings when using the torque app.

I am sure what I monitor at the moment is the spoofed soc so I think I should get the real soc readings displaying alongside the spoofed soc.....

Many thanks, anthony.
