Thanks. How did you get the numbers?

I had to buy 10 of each, only want 2, so if anybody else wants some, happy to share

Thanks Cas and Richard. I did indeed rewire the charging plug, (which is wired in permanently to the bike under the seat), swapping L1 and L2. Hey presto, charging striaght to110% off a 13A plug.

Of course this just proves that the first 3kW charger is on the way out, I wonder if I can get a second hand one?

fully charged now

Not clear which charging options you have?

I in the UK and I have an SRF with the EU mennekes type 2 charge socket, and I have the charge tank, so I have three chargers on the bike: 3kW, 3kW and 6kW. These are on each of the three phases of the socket (L1, L2, L3). If I have a three phase charge point I get 12kW.  However, if the charge point is only single phase (chargers rated at 7 or 11kW, typically household chargers) only L1 is connected, and I get 3kW.

However if you rewire the charge lead to swap L1 and L3, which is what I have done, and of course if you have the 6kW charger, and you have a 32 amp supply (you say your BYD takes 7kW, so yes) and your cable is rated at 32A ( set by a resistor between PP and earth pins in side the cable) you will get the 6kW. OK 5.8kW, were talking rounded figures here.

Do you have the 6kW charger?  if not this info isnt much use, sorry.

Thanks guys, appreciate the confirmation. Useful to think about not charging at high %, thanks Dom.

Just got this back from Davant:

I have reviewed the logs attached and it all seems normal with no signs of faults.
 
Reasons for battery charging difference-
The BCB is made up with different cells with different chemistry than the original HM battery, the BCB is also a larger battery with a difference from 14.4kw to a 15.6kw output which obviously give more cell output and greater power but will increase the charge time slightly.
 
The BCB charges at a different rate and in a different way to the HM battery and a drop in Kw is normal, the temp of the battery also has a great affect on the charger output and the closer the battery gets to full the charge rate will drop.
The ideal battery temp to get the full optimal charge is 30-45% but obviously this is not easily done here in the UK (specially at the moment) so maybe worth advising to charge directly after a long ride if this is what the customer is after. The BCB will charge from 0 to 95% in 1.15 hours in an ideal temp range.
 
Please advise the customer that this is normal operation of the charging cycle and that Zero are currently working on new software to improve the charge rate.

EDIT: i think he means 30-45 degrees C, not %

Sounds very familiar.  I had this, single charger down to 1.3 kW.  Long charge time! Weirdly it started charging went to 2.3kW, then immediately dropped back to 1.2/1.3kW.  Note this behavior was immediate upon a software update which said it offered better battery management...

I took it in for a new battery ( separate story) and the dealer (DAVANT, Uk), looked at it and said that the fans on the chargers weren't working. They blew compressed air through the stationary chargers and got a lot of muck out (!) and the charger fan then started (I knew a noise was missing, could not work out what it was..)  it took them a while to get it up to 2.2/2.3 kW.

Sadly, I have to say that I have the new battery, but the charging rate now starts at 11.6 kW (Premium and charge tank), but then drops fast. at 61% I'm only charging at 6kW, by 80% im only doing 4kW, etc etc.  On the bright side the SOC seems better prediction  and I dont have magic charging anymore.

I thought this behavior would disappear with the new battery, Hoping it was a simple software issue, and I'm not that impressed with the cleaning by compressed air injection, My first guess is a charger gone or on its way out.

I would really like to monitor the charge rates over time, ideally to see each phase contribution, which should ID any poor charger. Anybody any idea how to do this?

So, does yours ramp up to 3/2.4kW and then straight down?  Can you hear the fan(s) start up at the beginning? worth  a look.

PS haven't fixed mine yet, in the email ether to Zero...

Charged the battery on a 22kW 3 phase ev charger and it said 11.7 kW, which means all 3 chargers are working fine. Phew.
However, even when left on overnight from 80% it never made it to 100%, stuck at 97/98% last two times. Does 100% still reset trip A? in which case its a nuisance.

parking thing brilliant, starting to use it all the time even on the level.

Did the fuse, for the cellular,  but no change. Did I have it all keyed off? Yes defo.  No ideas what to try next.  Bloody electronics.

Brilliant bike :-)

Its great to have the new battery installed, and I picked up the new dash and parking too.

Sadly, as always, A few issues:
1 The cellular has stopped working and theres no switch to re energize in in the latest software.
2 The charge rates have gone down from 2.3 kW to 1.7 Kw (at 81%). Is this the new battery charging, or is my charger on the way out?
3 The parking is great, but no instructions. I'm toggling between reverse and forward by hitting the engine on off switch. Is there an easier way?
4 I see the charge is limited by default to 90%, but the setting seems to have disappeared. How do I get 100%?

I was told the battery was new and unlocked, not so sure what that means.
Maybe I should read the 2023 SRF manual - does this have stuff about these issues in it?

Thanks all. pete.
