The automaker says owners of battery-powered vehicles might wonder how much charge they should keep in their batteries and whether their batteries will become depleted if their vehicle is not used and recharged regularly.
In a press release, Ford calls upon battery expert Bob Taenaka, senior technical leader, Battery and Cell System Development, to share some tips on how to keep an electrified vehicle in top condition while self-isolating.
Tips To Keep Your Battery In Good ShapeFirst, Taenaka says the most important thing is to make sure your 12-volt battery stays charged and that your high-voltage battery has adequate charge - 10 percent or more. This will prevent it from potentially draining to zero percent. If you have driven and/or had your vehicle on plug for a total of at least 8 hours within the past month, the 12-volt battery should be adequately charged. For longer periods of time between driving, you should also take additional steps. Ford says you should always consult your owner's manual for specific instructions on Vehicle Storage for longer than 30 days.
If you're storing your battery electric vehicle without plugging it in, Taenaka recommends keeping it at a state of charge between 10 percent and 80 percent. (Ford says its hybrid and plug-in hybrid vehicles are designed to stay above a 10 percent state of charge during normal operation.)
A high-voltage battery above 10 percent state of charge can go for more than six months without charging, but the 12-volt battery will drain much faster, especially when connected to the vehicle. If you do not plan to drive your electrified vehicle for longer than 30 days, Taenaka recommends following these steps for the sake of your 12-volt battery:
"If you are storing your vehicle for longer than 30 days without use, we recommend disconnecting the negative terminal of your 12-volt battery," says Taenaka. "This avoids depletion and potential damage to the battery, which runs the internal systems such as heating -- without the need for monthly maintenance."
Disconnecting the BatteryIf disconnecting the 12-volt battery, follows these additional tips:
Warm Temps And BatteriesWarm temps can also have an impact. Electric vehicle batteries are designed to handle long-term storage outside in direct sunlight. Taenaka says that if you are experiencing extreme hot weather and the vehicle needs to be stored for more than 30 days, if practical for you, store your vehicle in a garage or in the shade to preserve battery capacity and extend its life span.
Note: Always refer to your owner's manual for important details about storing your vehicle and removing it from storage.
