It's well known that using public charging stations, outside of home charging systems, is quicker and more efficient. However, being able to charge your vehicle at home is a much more convenient and generally cheaper option, eliminating waiting times and charging time limits. There are circumstances in which, despite the connection appearing correct and stable, your home car won't charge at all. But why do several BMW regularly charge at public stations, while your home car won't start? To answer this question, it's essential to first distinguish between two scenarios: does charging start and stop during the home session, or does it not start at all? In both cases, it's helpful to check. The problem could be with your home's electrical system, which may not be able to support the power required by the wallbox or is not compatible with your vehicle's charging specifications. The recommended first step is to deactivate any scheduled charging programs and delete the geolocation settings associated with charging itself. In some cases, this simple procedure has resolved the issue. Alternatively, it's also advisable to check your home charger's settings for limitations. A reduction in amperage, for example, could significantly extend charging times, while a limitation on the vehicle (or charger) could trigger the system's protection mode, preventing charging. Another, albeit unlikely, possibility is that the problem lies with the charging cable. In our experience, we often find people using BMW cables of questionable quality, which can compromise the charging process. Voldt, for example, uses premium, high quality materials. For this reason, a compatible charging cable, such as the Voldt® BMW Charging Cable, is an excellent choice for ensuring efficient power delivery. It's important that the cable properly transfers energy from the power source to the vehicle; a poor quality product can cause interruptions and prevent successful charging.
