A method for controlling a lower limit of a state-of-charge state of a power battery, and a vehicle are provided, the method includes: detecting, by a detection unit, a minimum ambient temperature and a minimum power battery temperature in at least one time period; evaluating, by an evaluation unit, a minimum power battery temperature in a preset time period after the at least one time period according to the minimum ambient temperature and the minimum power battery temperature in the at least one time period; determining, by a processing unit, a minimum state-of-charge value that meets a start-up power requirement of a vehicle engine at the minimum power battery temperature in the preset time period, and adjusting a lower limit value of the state-of-charge according to the minimum state-of-charge value, in order that the vehicle can be powered-up by a state-of-charge value of the power battery at low temperature environment.

A vehicle includes a refrigerant system having a chiller and a coolant system having a chiller loop and a radiator loop. The chiller loop is arranged to circulate coolant through the chiller, and the radiator loop is arranged to circulate coolant through a battery, a radiator, and a bypass valve connected to a bypass conduit. A controller is configured to, in response to an ambient-air temperature exceeding a battery-coolant temperature, actuate the valve to circulate coolant to the bypass conduit to skip the radiator.

A control device is provided, which includes: a destination determining unit configured to determine a destination of a hybrid vehicle that includes an engine, a motor and a battery and is able to supply waste heat from the engine to the battery; a arrival judging unit configured to judge whether the hybrid vehicle can arrive at the destination with a remaining capacity of the battery based on the remaining capacity and a temperature of the battery; and a vehicle control unit configured to control the hybrid vehicle to start the engine and supply the waste heat from the engine to the battery when the arrival judging unit judges that the hybrid vehicle cannot arrive at the destination.

The present disclosure provides a battery pack control method, a system, and a vehicle which are applied to a vehicle having a vehicle-mounted communication terminal, and relates to the technical field of automobiles. Wherein the vehicle includes a heating module and a cooling module; when the vehicle is in a powered-off state, and when a trigger condition of the predetermined timing task is reached, the vehicle is waken up by the vehicle-mounted communication terminal, and then the temperature of the battery pack is controlled so that the temperature of the battery pack is maintained within the preset range, so as to restart and use the vehicle; thus to solve the problems in the prior art that after the vehicle is in a powered-off state, the temperature of the battery pack cannot be controlled using a heat management system, and the temperature of the battery pack is easily too low or too high due to a lower or a higher ambient temperature.

An operating strategy optimized for dynamic requirements for 48V drive systems of MHEV.

A vehicular breaking force control system that includes a control device including a processor that acquires a plurality of longitudinal accelerations from a driving assistance system, and calculates a driving/braking request when the vehicle is in a coasting state in which an acceleration operation or a deceleration operation are not performed during running of the vehicle. The processor further acquires a driving force lower limit set for a powertrain actuator having a set gear ratio, and distributes the driving/braking request to at least one of (i) a powertrain system including the powertrain actuator and (ii) a brake system including a brake actuator. The driving/braking request is distributed to the at least one of the powertrain system and the brake system based on the acquired driving force lower limit.

A method for controlling heating of a hybrid vehicle is provided. The vehicle includes a duct flowing air into the indoor of the hybrid vehicle from the outside, a heater core for circulating the coolant heated from an engine inside the duct, a PTC heater heated by the power supplied from a high-voltage battery of the hybrid vehicle inside the duct, and a controller. The controller operates the engine and the PTC heater and heats the air flowing into the indoor of the hybrid vehicle through the duct. The voltage supplied to the PTC heater from a low voltage DC-DC converter (LDC) is changed based on the state of the engine and an auxiliary battery for supplying power to an electric component of the vehicle to apply power to the PTC heater.

A system for mitigating thermal runaway in a battery-powered electric vehicle (EV). The system includes a gas sensor configured to measure a level of at least one type of gas in a vicinity of a battery of the EV, a thermal event detector configured to determine, based on the measured level of the at least one type of gas, that the battery is experiencing out-gassing, and a communications interface configured to transmit an alert to a fleet management system regarding the out-gassing of the battery. The fleet management system alters an assignment of the EV in response to the out-gassing of the battery.

There is provided a hybrid vehicle that enables user to be more appropriately notified of a control effect by performing a drive support control. A hybrid vehicle includes an engine; a motor; a battery; map information; and a control device programmed to set a drive route from a current location to a destination, to create a drive support plan that assigns one of drive modes including a CD mode and a CS mode to each of drive sections of the drive route, and to perform drive support control that causes the hybrid vehicle to be driven along the drive support plan. The control device accumulates control effect obtained by performing the drive support control and notifies the control effect when the hybrid vehicle reaches the destination. The control device deletes the control effect when the predetermined deletion condition is satisfied.
