If there's one thing the typical electric car drivers desires, it's awareness. They want to know what to expect, and they want certainty about it. They want to be sure that if they plug their car in at night, the battery will be fully charged the next morning. They want to be sure that if they're going on a long trip, they'll have enough charge to handle the journey. Sometimes this doesn't happen. This is the case, for example, with the BMW i5: when plugged in at home, charging can sometimes be interrupted randomly. This happens randomly, without warning. Yesterday, charging at home was completed normally, but today it stopped. Why? There are several possible causes. This could be due to problems with the charger, the charging station, or it could be due to problems with the car's charging capacity (which will tend to decrease over time). Low temperatures can also significantly slow down charging. Before drawing conclusions, it's best to proceed by trial and error to avoid hasty and misleading diagnoses. While it may be a cause, a new cable is unlikely to solve the problem. On the contrary, the charger deserves a more thorough analysis, as this "intermittent" charging could indicate a fault with the charger. It would also be advisable to consider the weather conditions: in cold temperatures, charging is more difficult, and it's not surprising if it stops. The home's electrical system also affects the battery charging process. Obviously, a modern and up-to-date infrastructure limits dispersion, manages the current better, and is less likely to shut down the power supply, as happens with an older home electrical system. What appear to be random interruptions, therefore, could make sense.
