A motor control unit, a control system, and a storage medium. The method of the present invention is applied to the motor control unit and comprises: when a vehicle is in a high-voltage power-on state, obtaining a plurality of effective temperature values for the same motor system; determining a corresponding initial temperature value according to each effective temperature value; determining the minimum value among all calculated initial temperature values as an initial environment temperature; when the vehicle is in a driving state and each initial temperature value is less than or equal to respective corresponding threshold, and the current temperature of a motor no longer rises, calculating differences between the current temperature of the motor and the corresponding initial temperature value and between the current temperature of a cooling liquid and the corresponding initial temperature value; calculating a temperature calibrate amount for the environment temperature according to the calculated differences.

A charging device wiredly transmits identification information to a power storage pack after the power storage pack is mounted. The power storage pack transmits via near-field communication a signal including the identification information received from the charging device. The charging device collates whether or not the identification information included in the received signal matches the identification information wiredly transmitted.

A first power storage pack wiredly transmits identification information retained in the first power storage pack to a charging device when the first power storage pack is detached from an electric movable body. The charging device wiredly transmits the identification information received from the first power storage pack to a second power storage pack. The controller of the second power storage pack transmits via near-field communication a signal including the identification information received from the charging device. The electric movable body collates whether or not the identification information included in the received signal matches the identification information retained in the first power storage pack.

The liquid coolant is an ionizable coolant, wherein a deionizing unit is provided and fluidly connected to the flow path for deionizing the liquid coolant to decrease its conductivity.

A method for propelling of a vehicle comprising a power train with an electric motor connected to a location in the vehicle intended for mounting of an energy supply unit intended for driving of the electric motor during normal operating conditions of the vehicle is described. The method comprises the steps of: connecting an electric power source to a power connection element mounted on the vehicle and being connected to the electric motor and to the location, disconnecting the location in order to accomplish a direct connection between the power connection element and the electric motor and propelling the vehicle by means of the electric motor powered by electricity from the electric power source. A method for manufacturing of a vehicle comprising a power train with an electric motor and a vehicle comprising a power train with an electric motor are also described herein.

Provided is a bootstrap method for registering a charging station (CS), which was in an offline state, to an electric vehicle charging station management system (CSMS) and operating same. The bootstrap method comprises the steps of: storing at least partial bootstrap information in a CS so as to configure bootstrap information; connecting the CS to a CSMS by setting a security channel between the CS and the CSMS for maintaining registration information about the CS; and registering the CS to the CSMS.

The present disclosure provides a system and method for selecting a battery pack that is used to pre-charge a high-voltage DC bus of an electric vehicle.
