In General use with a Hyundai Ioniq EV - advice on prolonging the life of the battery over its lifetime
Expert:  Robert replied 3 months ago.

Hi..there..

There is alot of things you can do to help prolong life time of the battery..of course during routine service/checks the elected garage qualified to work on EV's can diagnostically scan the car and its battery health...a few things you can do yourself..ie:- speed - meaning if you floor it suddenly then this can bring battery state down quicker then it would moderatly driving,progresive take off - 2nd is weight - unessesary weight means more effort on the motor meaning more from the battery.. 3rd is always charging upto 100% and running at a discharged rate of below 10/20% alot of manufacturers recommend you charge upto 80-90% this means room for regenerative braking,they also recommend that you try to avoid discharging to below 20% so planning is essentail to find charging points on long journeys... 4th is heat alot of ev's use thermal management to stop battery overheating which take power from the battery..so summer time if the cars sitting in an area that subject to continuos sun/heat then it might be best to find a shaded area... hope this helps

Expert:  Robert replied 3 months ago.

Well i stated that above...

Always charging upto 100% and running at a discharged rate of below 10/20% alot of manufacturers recommend you charge upto 80-90% this means room for regenerative braking,they also recommend that you try to avoid discharging to below 20% so planning is essential to find charging points on long journeys..any further questions?
