Considering the distance you cover every day, we would recommend you go for an EV from the proven players such as TVS, Bajaj, Hero (Vida) or Ather with a battery capacity of 5kWh or more, so you have a healthy buffer for errands and spontaneity.
Since TVS is the only one to offer an EV with a battery capacity suiting your needs in the form of its iQube ST 5.3, that is the option we would recommend. Not only has the iQube cemented its reputation for reliability and comfort, it has now been on sale for close to six years without any major problems reported by owners. It also falls well within your budget.
