There is provided a method and apparatus for requesting a battery to be unlocked from an e-vehicle using an application for authorising a user to unlock the battery. A request is received at a cloud-based server, to unlock the battery from the micro mobility vehicle. Authorisation data is provided, by the cloud-based server, if the user making the request is permitted to unlock the battery at the e-vehicle. Further, methods and apparatus for controlling a self-serviced battery swap station by a cloud-based server are described. Battery data may be obtained from a cloud-connected battery swap station, the obtained battery data may be used to generate battery charging control data. The battery charging control data may be sent to the battery swap station.

The invention relates to a method for deterring theft of a vehicle having a three-phase electric motor without a freewheel (10), comprising the steps of using the motor in a generator mode to power a motor control circuit (14) in an initial phase of rotating the motor through motion of the vehicle; and, when the power supply level of the control circuit reaches a first threshold (Vmin), connecting by the control circuit first and second phases (b, c) of the three-phase motor continuously to a first power supply line (Vss), whereby the first and second phases are short-circuited and cause an increased braking force of the motor. During this time, the third phase of the motor may be connected to continue to supply energy to the control circuit.

An activity tracker includes a device that includes a sensor component, a radio, and a mounting member. The sensor component is configured to obtain bicycle route information based on information from one or more sensors. The sensor component detects pedal proximity and calculates a pedal rotation speed based on data provided by an integrated pedal cadence sensor. The radio is configured to wirelessly communicate the bicycle route information to a remote computing device. The mounting members are for mounting the device to a bicycle frame.

Among others, the present invention provides electric scooters each including a vertical tube, a handle bar element, a platform configured to support a rider, at least one front wheel and at least one rear wheel, an electric motor configured to provide a mechanical power to at least one of the front and rear wheels, and a battery housing configured to removably receive and hold one or more battery packs. The one or more battery packs are configured to power the electric scooter, and at least one battery pack is capable of being used as a power supply of an electric power or gardening tool.

The present utility model discloses a two wheel electric motorized cycle frame incorporating a case-free battery, including a frame main body with a battery containment framework disposed on the frame main body. The battery is contained by the battery containment framework. At least one side of the framework is removable to facilitate replacing the battery, and partition boards are inserted in the framework to separate out a protective cavity for electrical connections. According to the present utility model, the battery is placed in the battery containment framework, so that a battery case is omitted. The battery is safely fixed in the framework, and one side of the framework is removable to facilitate replacing the battery. Furthermore, the partition boards are disposed in the framework to separate out the protective cavity for electrical connections of battery cables, thereby solving the problem that the battery cables are exposed to the outside and cannot be effectively accommodated due to replacement of an enclosed battery case with an open framework.

Techniques are disclosed for systems and methods to provide a configurable electric micro-mobility vehicle that can be configured with modular accessories. The micro-mobility vehicle is configurable by including a structure that is adapted to receive and secure one or more of the modular accessories within a short amount of time. The micro-mobility vehicle may include a battery compartment for receiving a modular battery pack and securing the battery pack to an electrical connector of the micro-mobility vehicle. The battery compartment may be physically coupled to a seat tube of the micro-mobility vehicle. The battery compartment may include an opening at one end of the battery compartment for inserting and removing a battery pack.

A retaining element provided for two-stage fastening to an accumulator or which is part of an accumulator, safeguards against removal from a retaining device. The retaining device is oriented toward the retaining element and is fastened in an interior of tubes of a bicycle frame of an electrically driven bicycle.

A device includes a battery case (42) that stores a battery (62A or 62B), a lock mechanism (133) that is capable of fixing and holding the stored battery (62A or 62B) in the battery case (42), and an operation member (44) that is capable of performing switching operation of the lock mechanism (133) between a battery-fixed state and a non-battery-fixed state. The lock mechanism (133) includes a movable block (160) which is supported by the battery case (42) in a displaceable manner. The movable block (160) has a battery restriction portion (160b or 160c) which restricts displacement of the battery (62A or 62B) in a separation direction in a state of being displaced to a battery fixing position, and a holding force receiving portion (160d) which receives a holding force for maintaining the movable block (160) at the battery fixing position from the operation member (44) in a state where the operation member (44) is operated within a predetermined positional range.
