A charging and discharging system includes: a rotary electric machine being able to output a driving force for traveling; a drive circuit unit for supplying electric power of a main battery to drive the rotary electric machine, and charging the main battery through regeneration of the rotary electric machine; and a control unit for controlling the drive circuit unit. The charging and discharging system is configured not to charge a backup battery connectable to the drive circuit unit through regeneration of the rotary electric machine.

Methods for managing charge status of an electric vehicle (EV) at a charge unit (CU) and systems that use cloud processing, are provided. One method includes detecting connection of a charging connector of the charge unit to a vehicle charge port of the EV. The method also includes receiving charge status of the EV while the charging connector is connected to the CU and activating a visual indicator at the CU. The visual indicator is set indicative of the charge status of the EV. The method includes changing the visual indicator as the charge status of the EV changes. The method enables a user device to receive notifications of charge status and communicate with cloud processing to request changing of the visual indicator of the CU to a non-full state even when the EV is at a full state of charging.

A system and method include receiving a temperature signal from a temperature sensor, controlling operation of an air conditioner condenser, and controlling an electric vehicle charger to operate to charge an electric vehicle battery only when the air conditioner condenser is not running.

A vehicle includes a traction battery subject to alternating cycling and storage modes and a controller. The controller is programmed to calculate an accumulated degradation for the traction battery based on a degradation profile for the traction battery. The degradation profile defines degradation accumulated over time and may differ based on the mode and temperature. The initial degradation value includes the accumulated degradation for the present mode and at least a portion of the accumulated degradation for the other mode. Degradation is then accumulated according to the degradation profile starting from the initial degradation value. The amount of accumulated degradation from the other mode that is included may vary based on the mode and the accumulated degradation.

A DC-to-DC converter may be disposed in a vehicle for converting a high voltage from a power source to a low voltage. The DC-to-DC converter may include a primary converter, a secondary converter, and a DC-to-DC module. The DC-to-DC module may control the operation of the secondary converter based on a set-point threshold and a power output of the primary converter, where the set-point threshold may be variably set.

Methods, systems, charge units, computer readable media, and combinations thereof are provided, to enable color coding of charging units (CUs), to provide a visual indication to users of when a CU is available, unavailable, in progress, out of service, etc. The method also include logic for finding charge units and identifying discounts are the identified charge units. The discounts can, in some examples, be provided by merchants that may be proximate or local to a charge unit. The discount can be in the form of a discount for the charge purchased or obtained at the charge unit or discounts for goods or services offered a location of the merchant. The method executed by a processor at a charge unit or by a cloud processing logic, or by a server or servers or over the Internet, or combinations thereof.
