Electric vehicles that use replaceable and exchangeable batteries and systems are provided. A system includes a battery carrier for holding a plurality of batteries. The battery carrier is connectable to a power source and the plurality of batteries are rechargeable and replaceable into and out of the battery carrier. The battery carrier includes slots for receiving the plurality of batteries and control systems for communicating over a network. The control systems are configured for identifying presence of batteries in the slots of the battery carrier and charge level of batteries present in the slots. The system further includes a server that communicates over the network with the control systems of the battery carrier. The server is part of a cloud system that manages access to user accounts. The user accounts are accessible via applications executed on user devices.

Disclosed are a battery swapping station and a control method therefor. The battery swapping station comprises: a first battery swapping platform being arranged between a first charging compartment and a second charging compartment; a first shuttle travels between the first battery charging compartment and the first battery swapping platform, a second shuttle travels between the second battery charging compartment and the first battery swapping platform; a control unit being electrically connected to the first shuttle and to the second shuttle, used for the following operation: when operating a same vehicle on the first battery swapping platform, if the first shuttle is executing either operation of battery unmounting or battery mounting, the second shuttle executes the other operation. Through the battery swapping station and the control method therefor, the waiting time for vehicles when swapping batteries can be reduced, thus increasing the battery swapping efficiency of the battery swapping station.

An electric vehicle battery replacement system having an ESS according to an embodiment of the present invention comprises: a battery containment facility for containing a discharged battery of an electric vehicle, and charging and storing the discharged battery; a battery transfer facility for transferring a pair of trays, in which a fully-charged battery that is fully charged by the battery containment facility is received, to a battery replacement place for the electric vehicle, and transferring the pair of trays, in which the discharged battery removed from the electric vehicle is received, into the battery containment facility; a power supply for supplying a driving power for each of the facilities; and a replacement facility operating terminal for providing a facility operating signal for each of the facilities, wherein the power supply receives, from a grid, a first power corresponding to a capacity price and a system marginal price set by the replacement facility operating terminal to use the received first power as a charging power for the discharged battery stored in the battery containment facility.

The vehicle battery pack exchange system herein described charges renters for the time use interval, the energy needed to recharge the battery pack, and the battery wear their use has caused. Data on battery wear accelerating stress parameters such as current, voltage, temperature, and state of charge is collected for battery packs rented to vehicle users. Wear rates are estimated from the collected data. Then either users are charged for the wear they cause or wear is limited to some predetermined wear rate and users are charged a predetermined battery wear fee. In either embodiment drivers are displayed information to adapt their driving to battery wear rates. Renters are charged for battery pack usage time, energy supplied by the rental station, and battery wear providing battery owners a secure return on their investment. This system accommodates both short term and sustained long term rentals. Long term rental of a single battery pack for local use gives convenience and low costs while short term rentals provide unlimited range via swapping exhausted packs for recharged units during extended travel.

One or more switchable magnetic systems is located near a battery attachment surface of an electric vehicle, where the battery attachment surface is configured to accept and electronically connect to a battery pack. The electric vehicle also includes a control system that operates the one or more switchable magnetic system switching from a first to a second state. In the first state the magnetic field of the switchable magnetic system secures the battery pack to the battery attachment surface so that the battery pack is electronically coupled to an electric motor of the electric vehicle. When the control system receives a message corresponding to removal of the battery pack, the control system switches the switchable magnetic system to the second state such that the battery pack is removable from the battery attachment surface.
