Power Adapters that are Safe to UseĪll of these power adapters will have a smaller, lower amperage plug (male blades) on one end, and a larger/higher-amperage receptacle (female terminals). If a plug goes in with little resistance, the receptacle probably needs replaced. A loose connection can easily generate enough heat to melt your plug or start a fire without tripping a breaker. Note that in any of these situations, and even when plugging your RV directly into a pedestal, a receptacle in poor condition is still a hazard. If there was a problem with the appliance, or its cord, you could easily melt it before the breaker is overloaded enough to trip.

If you have convenient access to workplace charging, that may also impact how often you choose to charge your electric BMW overnight.Just about every RVer has a few power adapters, often referred to as “dogbones,” to make sure that they can connect to whatever power is available to them–this post will go over which power adapter types are safe to use, and which ones you might want to carry. Keep in mind that how often and how long you should charge your electric BMW depends in part on what kind of home charging option you have and your daily driving needs. Use DC and high-power DC chargers as often as you need, in order to extend the mileage of your electric BMW in a short period of time. While it takes longer, it is less stressful on the high-voltage battery and also a more cost-efficient way to get your range topped up. When not driving your electric BMW for a longer period of time, leave the battery between 20% and 80% charged. However, it is not recommended to charge up to 100% every day – as this can harm the battery in the long run. You can charge the battery up to 100% when you have to rely on the entire driving range of your vehicle (for a longer trip), as occasional charging to 100% doesn’t harm the battery. Staying between 20% to 80% battery capacity should leave you with enough driving miles – and you can use iDrive or your My BMW App to set a target state of charge. The amount of miles you drive daily will determine how much charging you will need. Similar to your cell phone, charging up your electric BMW before a day’s use is simple.
