Things that can be run on the normal battery?

[Gazz7]

Morning all,

I managed to track down a Trophy SR on Sunday which I pick up tomorrow, realised pretty quickly I wasn't going to come across the LR before August, so being an impulse buyer I plunged straight in.

I know I have a lot of reading through the forum to be able to get the best enjoyment and practicality from the car, but I was wondering does anyone have a list of things that can be safely run from the normal battery so I don't start off on the wrong foot and drain the car before I actually get out on a decent run?

The only thing I know of for definite are the heated seats.

I was beginning to question whether I had made the right decision on the SR, thinking that what's the point of running the car at 60% (between 20% to 80% charge), that was until I read a post on here explaining the difference in batteries between the SR & LR, and that the SR will charge to 100%.

So any help is greatly appreciated, I have a million questions flying round inside my head, but I am hoping most of them will become clear once I see the owners manual.

In very simple childlike terms (because I am a simple childlike person), the BIG battery makes the car move. The LITTLE battery powers everything else exactly the same as an ICE car.
You can safely do everything in an EV with the little battery that you would do in an ICE car, and in exactly the same way the little battery will run down unless it is charged. (in an ICE by the engine, EV by the big battery).

Except the heater is run off the HV.

There's a heater !

A serious omission, but in my defence the question was what can be run on the little battery, to which the answer is the same as in an ICE car including not the heater.

Two pennies worth !.
Power to supply the cabin heater element, does come from the HV side.
The heater blower / fan motor however, is powered by the 12 volt battery.
In this picture ( taken from a Tesla M3 ) the orange high voltage cables can be clearly seen running along side the heater box.
These power the heater element inside of the heater unit.

Hi Gazz, which post did you read about charging the SR to 100%? I'm new to EVs and thought it was best to keep it between 20 and 80% day to day and only put 100% in if you're going for a long journey.
Thanks,
Rob.

Thanks,

SR are LFP battery chemistry which are not known to degrade a lot when compared to NMC chemistry of LR and so you can never set custom SOC levels for SR cars in the iSmart app and the entertainment console of the car. It will always be set to 100%. Where as you can set custom SOC on LR. It is advisible to charge to 80% for normal commutes and only 100% for a long trip on LRs to help keep the batteries in a good state over time.

Rob, If you search for a thread called Home Charging, the answer from Mihir is there along with a few others.

The big battery is way bigger than what I presume you mean the "normal" battery which is a hangover from the combustion engine but also charged from the bigger battery. The irony is that the "normal" battery wakes up the bigger battery and if the "normal" battery gets too low then you end up with a dead car until you can "jump" start it, so pretty similar to a combustion engine! Just use the car "normally", worrying about what runs off the "normal" battery is not a good place to go.

@Gazz7 ,@Robt : I learnt it myself from here - Thread 'Setting target battery level issue' Setting target battery level issue

Just goes to show how wonderful our community and members are.

My suggestion to all the new members and new EV owners like me would be to go through threads and posts on this forum. There are so many experienced people and EV owners here who share so much of knowledge and information about the car and things in general and are very helpful and kind. I have greatly benefitted by it and learn every single day.
