Hi all sorry if this is a silly question will hopefully be receiving my Hyundai Tucson next month and will hopefully be charging it from home. I was wondering how much electricity would it use? How do I work it out?

here is how I have worked out and hope I am right

 

so the battery size is 13.8kwh. If I am paying 0.37p per kw does that mean it will use 13.8 and I will pay £5.10p 0% to 100% (0.37 x 13.8)

 

or am I wrong on the above calculation

Thanks for any help and sorry for the possible silly question lol

Charging to 100% is always an issue much cheaper to go to 85% but what you need to calculate is the mileage for that cost is it beneficial

I am the carer / driver for my wife who cannot drive due to disability

If your on economy 7 tariff then charge at night for 18p per kwh if key Meter of 13p if direct debut.

I didn’t think their was any price difference between 85% and 100%, I thought it was only a time difference ie the charging curve flattens off hence more time.

SOUNDS RIGHT.. IT DOES TAKE A BIT LONGER GOING TO 100 BUT IF YOUR NOT IN A PARTICULAR HURRY THEN THATS THE WAY TO GO AS YOULL GET FURTHER AND BATTERY WILL BE LOOKED AFTER.

Current Car: Hyundai Kona Premium EV...2 way 40kg hoist
Last Car: Toyota C-HR Excel Hybrid...4 way 80kg hoist

Not that simple. I’m afraid.  Is the battery capacity you quote the total capacity or the usable capacity?  It’s the usable capacity that you use and replace, so that’s what you use to calculate.. Also the charging process is only 85 to 90 efficient. There are heat losses in the voltage conversions involved.  There are more expert people than me here who may be along to go into it deeper.

To charge your battery will normally require 9.6 kWh taking into account any losses, 30% of the capacity is kept in reserve to protect the battery, occasion the battery go as low as  20% however that is very rare (I occasionally use this function to clean and rebalance the battery cells, that a different subject).

You will find the vehicles battery is most efficient at 25 degrees C above and below that temperature the battery efficiency degrade 1% per degree C, i.e. 25% less efficient at 0 degrees C, but to be honest with vehicles regenerative recovery system you will hardly notice it.

Expect around 28/32 miles in the summer and 18/20 miles in the winter, 6000 miles per year expect to use 1300 kWh.

Hope this helps

Unfortunately I have suffered a brain injury and occasionally say the wrong thing.
