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.

A vehicle electricity storage system includes a control device including: a calculation unit configured to calculate an internal resistance value of the battery based on the voltage value and the current value; a derivation unit configured to derive an estimated internal resistance value, which is an estimated value of the current internal resistance of the battery, based on the calculated internal resistance value calculated and the current voltage value; and a setting unit configured to set a charging electricity upper limit value, which is an upper limit value of charging electricity for charging the battery, based on the derived estimated internal resistance value, the current voltage value, and a current value at present. The derivation unit is configured to derive a greater value as the estimated internal resistance value, as a difference between an upper limit voltage value of the battery and the current voltage value becomes smaller.

A control device of a powertrain system executes a control input determination processing and a system control processing. The control input determination processing includes a co-state variable determination processing to update a co-state variable p of an optimization problem for each time step and a control input calculation processing. The co-state variable determination processing includes an initial value determination processing that determines, as an initial value of the co-state variable p, the sum of a base value of the initial value and an external charge/discharge correction value. The base value is a final value or an average value of the co-state variable p during the last control time period. The external charge/discharge correction value is determined based on an external charge/discharge amount obtained by subtracting a SOC at the end of the last control time period from the SOC at the start of the current control time period.

A hybrid powertrain system and method includes a prime mover driving a generator/motor to produce an AC power output. The AC power output is applied to a rectifier which is controlled to transform the applied AC power to DC power to supply a DC Power bus at a selected voltage and current. An energy storage device is also connected to the DC power bus and the current flow between the energy storage device and the DC power bus is monitored and compared to preselected values and the results of that comparison are used to alter the operation of the rectifier to increase or decrease, as needed, the current provided to the DC power bus as electrical loads on the DC power bus change.
