Provided are a method and device for estimating the utility of replacement of a battery pack for an electric vehicle, and a charging management method and system based on the method and device. The method comprises the following steps: acquiring state data associated with a first battery pack and a second battery pack, the state data comprising usage history of the first battery pack and performance parameters of the first battery pack and the second battery pack; and determining a utility value according to the state data, wherein the utility value is used to characterize a degree of impact of an operation of replacing the first battery pack with the second battery pack on the service efficiency and service life of a battery pack set to which the first battery pack and the second battery pack belong. The method facilitates improving the service efficiency of a managed battery in a battery swap mode and extending the overall service life thereof.

Method and device for determining utility of replacement of battery pack for electric vehicle

Provided are an electric drive system for a motor vehicle and a motor vehicle using the electric drive system. The electric drive system for a motor vehicle comprises: an inverter unit () configured to convert externally-supplied DC power to AC power; an electric motor unit () configured to convert the power from the inverter unit () into mechanical rotation and output the mechanical rotation from an output shaft (); and a gearbox unit () configured to decelerate the rotation transmitted from an input shaft () and output the decelerated rotation. The electric motor unit (), the gearbox unit () and the inverter unit () have respective independent enclosures. The electric motor unit (), the gearbox unit () and the inverter unit () are detachably and mutually connected in an axial direction along the input shaft () of the gearbox unit () with the gearbox unit () positioned in between. The enclosure of the inverter unit () has the minimum thickness in the axial direction.

Electric drive system for motor vehicle and motor vehicle using same

A system and method for monitoring the health of smart battery packs in an electric vehicle and determining when one or more of the smart battery packs needs to be replaced. In addition, the system and method locate optimal smart battery packs to exchange with the one or more battery packs that need to be replaced.

System and method for tracking and storing battery data, and utilizing the data to appropriately match batteries upon swapping

A battery for a vehicle having a fixed battery pack and a replaceable battery pack. The replaceable battery pack has electronic or mechanical locks to semi-temporarily hold the replaceable battery pack in place. The fixed battery pack is held in place via permanent or semi-permanent fasteners such as bolts. A battery controller controls the replaceable battery pack to power motors of the vehicle before controlling the fixed battery pack to power motors of the vehicle.
