Current battery don't love heat to. In hot climate you must cool batteries. However, electric cars is not bad idea per se, but THEY push these shit although technology are not ready to carry all real world demands. Add to this that electric cars are all but no ecology friendly. Batteries have very limited life time. Manufacturing is one of most envirnoment harmful process. Also recycling is limited, also very harmful for envirnoment .... and most manufacturer ( including shitty Tesla ), don't allow owners to change only cells which are die... no, no, you must buy complete battery pack and waste pack which have sometime only one dead cell.
