1. A vehicle comprising:
- a climate control system;
a motor configured to provide drive torque;
a battery for supplying power to the climate control system and the motor; and
a controller configured to;
receive input indicative of a battery state of charge (BSOC) and a state of charge (SOC) recalibration request, anddisable the climate control system, override the request and reduce the power available to the motor, when the BSOC is less than a discharge limit.

Abstract
A vehicle is provided with a climate control system and a battery that is connected to the climate control system for supplying power. The vehicle also includes at least one controller that is configured to receive input indicative of a battery power limit and a battery state of charge (BSOC). The at least one controller is also configured to disable the climate control system and reduce the battery power limit to an intermediate power limit, when the BSOC is less than a discharge limit.

13. A method for limiting operation of an electric vehicle, the method comprising:
-
supplying battery power to a motor for vehicle propulsion; receiving input indicative of a battery state of charge (BSOC), a state of charge (SOC) recalibration request and a defrost status; reducing the battery power available to the motor and overriding the request when the BSOC is less than a discharge limit; and disabling a climate control system when the BSOC is less than the discharge limit and the defrost status is inactive. - View Dependent Claims (14, 15, 16, 17, 18)
