Can you charge your electric car at Tesco for free?
In fact, tesco decided to implement a fee for customers using all tesco car chargers, regardless of the kw rating. Unfortunately, this means that in 2026, tesco electric car charging is no longer free, with costs starting from 44p per kwh, up to 69p per kwh. Fully charging a car with 100kwh capacity, for example, could cost around £27. Tariffs can vary, and some electricity providers might include variable tariffs, such as cheaper charging at less busy times of the day.
How much charge do electric cars lose when parked?
Whilst lithium ion batteries do lose charge when the car is parked for an extended period, the good news is that this is usually a very minimal amount of the overall charge. Most electric cars can expect to lose only lose a few percent of their charge a month if sitting idle. So is it bad to charge an ev to 100? No, if you are doing it once a week with lfp, or keeping it even more rare with nmc batteries. Evidence suggests that charging ev battery to 100 percent more often than that would lead to possible higher degradation.Generally, most EVs can sit for months without charging, providing they are stored at an 80% charge in a temperature-controlled environment. But be warned — if your EV battery drops to 0% and sits there, it can damage cells and permanently lower your high-voltage battery’s capacity.The 80/20 rule To prolong battery life, it is recommended to charge your EV up to 80% and avoid letting the battery drop below 20%. This should be perfectly feasible for daily usage, but if you’re going on a long journey, its important to check your battery level matches the required distance.
