A management server is configured to perform a process including: setting a basic fee of a first monthly fee when a utilization manner is battery lease; setting discount rates based on the weight, capacity, manufacturer, degree of initial deterioration, amount of power consumption, number of times of performing quick electric charging, utilization region, and utilization period of the battery; determining the first monthly fee; setting a basic fee of a second monthly fee when the utilization manner is vehicle lease; setting discount rates based on the weight of the battery, a utilization region of the vehicle, and a utilization period; determining the second monthly fee; and determining a total monthly fee.

Rental fee setting apparatus, rental fee setting method and rental fee setting system

A management server performs a process including: when there is a request to partially replace a battery, obtaining a usage history of the battery; obtaining each cell's full charge capacity; determining a cell having a smallest full charge capacity as a cell to be replaced; calculating an average value of the full charge capacities of the plurality of cells excluding the cell to be replaced; extracting a selectable cell from inventory information; selecting a replacement cell; setting a replacement fee corresponding to partial replacement; and when entire replacement is requested, setting a replacement fee corresponding to entire replacement.

Replacement fee setting apparatus, method and system

A management server is configured to perform a process including: a step of obtaining a utilization history of each user in the previous month when a condition for performing a dividing ratio setting process is satisfied; a step of updating a utilization record evaluation; a step of calculating a first dividing ratio; a step of updating a driving record evaluation; a step of calculating a second dividing ratio; and a step of setting a dividing ratio.

Information processing device, information processing method, and information processing system

A management server is configured to perform a process including: obtaining, when an electric vehicle is returned, returning date and time, a returning location, and a use history of a vehicle; setting a fee-returning rate in accordance with a SOC at the time of renting, a SOC at the time of returning, the number of times of performing behaviors contributing to deterioration of a battery, and a leaving time in a state contributing to the deterioration of the battery; setting a correction coefficient in accordance with a cause of a behavior contributing to the deterioration; setting the fee-returning rate in accordance with the returning location and the returning time; determining the fee-returning rate; and performing a process for providing points corresponding to the fee-returning amount.

A management server performs a process including: when an electric vehicle is returned, obtaining a usage history of the vehicle; calculating a ratio of a non-traveling period of time of the vehicle; setting a discount rate based on the ratio of the non-traveling period of time; setting a discount rate based on how many times the vehicle is rapidly accelerated; setting a discount rate based on how many times the vehicle is rapidly decelerated; setting a discount rate based on environmental temperature; setting a discount rate based on a parking environment; setting a discount rate based on an SOC history; and setting a rental fee.

Rental fee setting apparatus, method and system

A motor drive device includes a stator, a rotor, a first output shaft being provided in the rotor shaft and integrally rotating with a first drive gear, a second output shaft being provided in the first output shaft and integrally rotating with a second drive gear, a first one-way clutch being provided between an inner periphery of the rotor shaft and an outer periphery of the first output shaft, the first one-way clutch transmitting only a driving force that operates in a first direction, a second one-way clutch being provided between the inner periphery of the rotor shaft and an outer periphery of the second output shaft, the second one-way clutch transmitting only a driving force that operates in a second direction that is opposite to the first direction, and a decelerator.

Motor drive device

A control system for a vehicle drive motor includes a motor torque obtaining portion, a current distributing state obtaining portion obtaining a state of current distribution to coils of respective phases of a stator of the motor, a temperature sensor detecting temperature of a specific phase coil, a motor torque control portion updating other phase estimated temperatures by using the coil sensor temperature and an added-up value of a temperature rise per unit time of each of other phase coils at each time point, the motor torque control portion controlling the motor torque by using the other phase estimated temperatures, wherein the temperature rise per unit time of each of the other phase coils at each time point is determined by the motor torque control portion in accordance with a combination of the motor torque and the state of current distribution at each time point.
