[V1.0 Beta 6]Charge larger battery
Hi!
I'd like the ability to trick my mower into fully charging a 2500mAh battery.
As it is now, it's only charged to about 1200mAh.

Re: Charge larger battery
Hi Iarsan,
you don't need a trick to full Charge your battery. Bu you need a trick to empty the battery complete (see below)
a - During charging the batterie voltage is being measured. Charging is stopped when the charge end voltage ist reached (about 21V)
b -The battery capacitiy then is explizitely set to 1200mAh.
c - In mode auto now the consumption of mAh is measured an integrated over time and then substracted from 1200mAh.
d - When the batterie capacity reaches 300 mAh the mover goes home for recharging.
To take advantage from your higher capacitiy you can do the following steps (without leaving your home):
1. Start the mower in mode auto
2. When the mower begins mowing switch it over to manuell.
3. When the battery voltage reaches 17.5V Switch it over to home
Now your battery is empty but has still enough capacity for the mower to go home.
17.5 V is a conservative discharge voltage to prevent damage to your battery .
If you forget to set the mower to home (3.) nevertheless the mower will stop at a lower discharge voltage than 17.5 V.
I use FHEM in kombination with the api do that all automatically. My Husqvarna 305 now mowes for more than 2 hours before recharge is necessary
Kind regards
Bernd

Re: Charge larger battery
Thank you Bernd.
May I ask which battery you are using?
Also, how often does one need to do that auto/manual/home-procedure?

Re: Charge larger battery
If your question is inspired by battery maintenance, then the answer is: Not at all.
A lithium battery is completely different from a NiMh-battery. It lasts best if it is only used with a shallow carging-profile: Never fully deplete, and never fully charge the battery. The voltages in the firmware are designed not to reach either the full- nor the empty-state, this way the battery lasts longer than when it is fully cycled.
You should only use the described trick if your time-window for mowing needs longer drives.
Best,
Detlev

Re: Charge larger battery
It is inspired by battery maintenance, and run time.
My idea was to use a 2500mAh battery instead of a 1600mAh one, to prolong run time, and decrease the number of charges needed per day.

Re: Charge larger battery
Hi Larsan,
you have to do that procedure which I described anytime you start the mower.
The only advantage of the procedure i described is, that you can do it from your living room and have not to go outside, by only using the the start in manuell mode.
That is the reason for my recommendation to do that automatically. The only way I see is to do that by FHEM unless admin integrates my proposal as a new mode into his SW.
The HX module has all information to to that already available. The procedure - I name it "extended" - is trivial. Perhaps you should make a feature request for that.
@top-gun
Using my procedure :
a
The full Status of the battery is furthermore managed by the firmware of the Roboter.
b The empty Status of the battery will be recognized by the firmware of the Roboter at a Level which ist lower then the 17.5V I propose. Thus care for the battery is furthermore guaranteed.
Kind regards

How do you do this automatically with the API? Do you have a howto?duese51 hat geschrieben: ↑So 23. Apr 2017, 17:28 Hi Iarsan,

Re: Charge larger battery
I will implement the method of duese51 directly into the Robonect Firmware, if he has no copyrights on it.

Re: Charge larger battery
It sounds brilliant, a little hard to constantly change from auto to manual and then to auto again before mower is going home. If you click on the auto just before the mover goes home, the times come up in robonect.

Re: Charge larger battery
That would indeed be awesome. What's the time frame for that? If it's too long, I'll whip up a script to poll and change statuses accordingly.
