T7 Ocean PHEV electrics

[AdamS]

Hi everyone,

Picked up a 25 reg Ocean PHEV last weekend, I have a few questions regarding electrics that I have found conflicting info on from various sources (the salesman wasn't really up to speed on the PHEV version).

• Pressing the 'max power/max charge' button on the dashboard, I've read that this should activate the inverter and charge the leisure battery from the PHEV traction battery. Does this only work when the vehicle is moving? I've only tried it while stationary on my drive but according to the control panel in the back of the van nothing was happening.
• The leisure battery went from 100% on Saturday, to 68% on Thursday, to 50% on the following Saturday, yesterday. In the course of the week, I unlocked and locked the vehicle three times and opened the powered sliding doors twice, nothing else running such as the fridge or AC/heating. That's it. Is this leisure battery drain normal, or is it possible it hasn't had the update/recall?

Thanks in advance.

The Max power function only works when the vehicle is being driven as it uses power generated by the drivetrain alternator/generator to charge the engine 12v battery and lithium leisure batteries and overcomes the standard 80% maximum charge boosting it to 100% charge.
The PHEV battery does NOT charge the Leisure Batteries.

I would get the Dealership to check that ALL available updates have been installed for the leisure electronics.

Let me please correct you to avoid confusions but it’s possible to charge the leisure batteries without driving. In fact I’m doing it periodically when my van is parked in my car park and it works very well

And how do you charge them.? By plugging into EHU mains, NOT PHEV charging.

and in answer to a question on this in comment for that video it was ...

"Engine doesn’t need to be running. Press brake, press start, it’s now charging."

As in, the leisure batteries are now charging with the max charge button from the Phev high voltage battery.

You need the "engine running" to use the fast charge button - so you can do it on the drive or at a campsite without a hook up - just having the ignition on wont work. California Chris did a video on this...

As for battery loss in the drive - I've left mine for a couple of weeks while away and while the leisure batteries have gone down a bit they very quickly charge up as soon as I'm on the road. I've turned off keyless entry as I've read this can cause power drain issiues in some circumstances - but you also need to make sure the software is up to date.

This is the case and how it works for me without turning on the engine

Thanks all, it was the pressing the brake that I wasn't doing. 'max power' is now charging the vehicle battery and then the leisure battery in that order. Dabbling in HMI design in my day job, I'm confused as to why the 'max power' function button lights up when you press it regardless, rather than only illuminating when it's operating.

I'll check the recall status and try turning off keyless entry.

Ive used this case to top up the leisure batteries from the HV PHEV battery when off grid. I reserve some HV charge for this reason and it works well. Just turn on the ignition ( ot the engine) and it used the HV battery to charge the leisures…

Sorry typo… not the engine as @Sanacar says!

For absolute clarity - you must have your foot on the brake as if you were 'starting the engine - just not the petrol engine'. If you just turn on the igntion by pushing the start button without your foot on the brake it wont charge the leisure batteries although it will look like it is. The way to be sure its working is via the control panel in the back.

I reserve EV battery charge and use this when camping without a hook up - works a treat. The only thing I have to remember is to use the Set Manually button every time I start the van. All too easy to pull up for a break or fuel etc and forget!

As I said in my previous post @Wannabecamperman the Drive train has to be activated to use the Max Charge facility, not necessarily moving .The EV battery doesn't charge the leisure batteries when parked and Drive train switched off.

I think most people take 'driven' as actually moving, WG. However I see that you have corrected yourself, so we're all on the same page as to the T7 PHEV's unique ability to charge the LFP leisure batteries when not actually being driven. Along a road. : - )
