Electric vehicle

EV_CHARGE_SWITCH

What it is

Start or stop charging the EV battery

The setting that the user wants. Setting this property to true starts the battery charging and setting to false stops charging.

This property is defined as VehiclePropertyAccess.READ_WRITE, but OEMs have the option to implement it as VehiclePropertyAccess.READ only.

How the ID is built

A property ID is a 32-bit value packing four fields. Reading 0x11200f42 apart:

Field	Mask	Value	Means
Group	0xf0000000	0x10000000	SYSTEM
Area	0x0f000000	0x01000000	GLOBAL
Type	0x00ff0000	0x00200000	BOOLEAN
Ordinal	0x0000ffff	0x00000f42	0xf42

Reading it from an app

CarPropertyManager mgr = (CarPropertyManager)
        car.getCarManager(Car.PROPERTY_SERVICE);

boolean value =
        mgr.getBooleanProperty(VehiclePropertyIds.EV_CHARGE_SWITCH, 0);

This property can be read and written, though an OEM may implement it as read-only. It fires a callback whenever the value changes.
