ChargingThe Big PictureAt home think: mobile phoneFor short trips: theres nothing more to think about!On the road think: planningprioritized charging sourcessuperchargerspublic chargers (e.g., J1772)private outlets (friends, relatives)

Continuing our discussion of tips and trick for the Model S, lets consider charging.For those who have never owned an EV, and that means the majority of all Model S owners, charging is the biggest question mark. But its really pretty simple.>> At home think: mobile phone; that is, you plug in your car every night, just like you do with your smart phone and in the morning it full.>> For short trips: theres nothing more to think about! The existing range of the Model S can easily accommodate them.>> On the road think: planning.If youre taking a long trip, it is necessary to plan in advance, so that youll have access to charging facilities where and when you need them.>> In order of priority, these are the charging sources youll need:>> Tesla superchargers that provide rapid charging on the go>> public chargers (e.g., J1772 chargers) that provide about 30 - 50 miles of range per charging hour,and when you reach your destination,>> private electric outlets of friends or relatives, if thats necessary.

Universal Mobile ConnectorThe Universal Mobile Connector (UMC) can be used with any electrical outlet for which you have an adapter110V is very, very slowavoid it except in emergencies!extensions for the UMC can be acquired in the aftermarketbe certain they have been designed specifically for EV chargingthe J1772 plug is the most common for level 2 public charging. A J1772 adapter is provided with the Model S

With the exception of superchargers that have their own heavy duty charging cable, >> youll need the The Universal Mobile Connector (UMC) to charge from any other electrical outlet for which you have an adapter>> charging from a 110V outlet is very, very slowavoid it except in emergencies!>> if you need more cable length, extension cables for the UMC can be acquired in the aftermarketbe certain they have been designed specifically for EV charging>> the J1772 plug is the most common for level 2 public charging. A J1772 adapter is provided with the Model S.

Charging Adapters and PortIMost people keep their charging adapters in the trunk, but there is a special space in the back of the glove box for a J1772 charging adapterEVannex also provides a charger adapter storage solutionThe easiest way to open the charging port is to hold the UMC sightly above and to the left of it and press the button on the top of the UMC connector (@NickHowe)

Most Model S owners do the majority of the charging at home. But there are times when youll need to charge on the road, and thats when you'll need the set of charging adapters that come with the car.

>> Most people keep their charging adapters in the trunk, but there is a special space in the back of the glove box for a J1772 charging adapter.>> In addition, EVannex also provides a charger adapter storage solution, called A.S.L.K., that is illustrated in the lower photo on your screen and provides convenient storage for all of your adapters in the trunk near the charge port.

>>When you do have to charge, either at home or on the road, the easiest way to open the charging port is to hold the UMC sightly above and to the left of it, and press the button on the top of the UMC connector. The door will pop open.

Charging Adapters and PortIIIf the charge port is stuck closed it can be pried open using a small plastic tool while pushing firmly on the bottom right corner (@NickHowe)closure is magnetic so nothing will break

Charging Adapters and PortIIIIf there is a power outage, your UMC connector may not releaseTap the touchscreen charge port button (even though it shows the door is open) and the UMC connector will releasedouble clicking on the key fob will also release the connector (@NigelM and @Mario Kadastik)

>> If there is a power outage while youre charging, your UMC connector may not release.To remedy this, >> Tap the touchscreen charge port button (even though it shows the door is open) and the UMC connector will release>> double clicking on the top of the key fob will also release the connector

Charging SettingsThe amperage setting for charging is GPS awarethe Model S will remember the appropriate amperage setting based on GPS location and will use default if the location is unrecognized (@DaveVA)If you charge at the range setting, that setting will not revert to standard the next time you charge. You must reset to standard manually (@JoshG)

>> The amperage setting for charging is GPS aware,>> the Model S will remember the appropriate amperage setting based on GPS location and will use a default setting if the location is unrecognized

>> If you charge at the range setting, that setting will not revert to standard the next time you charge. You must reset to standard manually using the small while slider indicator below the green range bar.

The Model S will warn you that repeated charging at the range setting is not recommended, so be sure to reset to standard at that time.

Charging TimingEach 10 percent of battery charge will take about an hour. Battery charge indicator has markings every 10%, so if you are at 60 percent of full charge, it will take about three hours to get to 90% of full charge (@MNGreen)If you have a HPWC, each 10 percent of battery charge will take about half an hour. (@MNGreen)

Each 10 percent of battery capacity will take about an hour. Although the length of charging time isnt particularly important when you charge at home overnight, it is important when youre on the road.>> The battery charge indicator has markings every 10%, so if you are at 60 percent of full charge, it will take about three hours to get to 90% of full charge >> If you have a HPWC, each 10 percent of battery charge will take about half an hour.

Charging Timing110V 10 - 20 amp provides 3 - 5 miles of range per hour of charging240V 30 amp (level 2)provides 18 - 22 miles of range per hour of charging240V 40 amp (NEMA 14-50)provides approximately 26 - 30 miles of range per hour of chargingHPWCprovides approximately 55 - 60 miles of range per hour of chargingTesla Superchargerprovides 150 - 170 miles of range in 20 minutes

When you fill an ICE vehicle, the flow of gasoline from the pump is predictable and rapid. With an EV, the Model S included, things are a bit different. The voltage and amperage of the charging circuit can have a significant impact on the time it takes to fully charge your battery.>> 110V 10 - 20 amp provides 3 - 5 miles of range per hour of charginga painfully slow rate of charge>> 240V 30 amp (level 2)provides 18 - 22 miles of range per hour of charging>> 240V 40 amp (NEMA 14-50)provides approximately 26 - 30 miles of range per hour of charging>> a high power wall charger, the HPWCprovides approximately 55 - 60 miles of range per hour of charging>> Tesla Superchargerprovides 150 - 170 miles of range in 20 minutes
