The first magnet is embedded in a slot of the main body via the press block. The main body includes a screw thread on the top of the main body. The battery cover is connected to the main body. The control board is mounted on the main body. The first silicon sleeve is sleeved on the power button, and the second silicon sleeve is sleeved on the regulation button.

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.

A battery management system and method that allows a battery bank to be composed of battery modules that can be heterogeneous with respect to each other. A battery bank composed of modules that support the battery management system allows for any subset of modules to be easily replaced with modules of different electrochemical characteristics. Each of the modules may also have a controller that manages cells of the module. The bank level controller and module level controller may operate to virtualize the hardware under their management to reduce or eliminate the heterogeneous features of the underlying cells and modules.

The present invention discloses an arc-shaped battery box structure for light-fixture, comprising an arc-shaped box body provided with a battery compartment and a battery cover covering the battery compartment in a matching and sealing manner, wherein, the battery cover and the battery compartment are in the shape of an elongated arc and matched with each other; an end portion of the battery cover is inclined and bent towards the battery compartment, or an open end portion of the battery compartment is inclined and bent towards the battery cover, or the end portion of the battery cover and the open end portion of the battery compartment are inclined and bent towards each other; and the battery cover and the battery compartment are quickly interlocked at an arc-shaped side wall.

A method for housing a battery used on a light-weight, motor powered watercraft includes the step of: providing a battery case having: a pod sized to house a marine battery, the pod having a cavity for the marine battery and an open top; a lid for at least water-resistant closure of the open top of the pod, the lid having a cavity and an open bottom, the lid is releasably attachable to the pod; and a floor releasably attached to the lid adjacent the open bottom, the floor adapted to hold controls for the light-weight, motor powered watercraft.

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.

A modular battery system provides propulsive power to the rotor system of an aircraft. The modular battery system includes an array of battery modules arranged in at least one stack. Each battery module includes a plurality of battery cells, a first side having positive and negative receptacles and a second side, that is opposite of the first side, having positive and negative plugs. The receptacles and plugs are configured such that adjacent battery modules in a side-by-side relationship are electrically coupled together via plug and receptacle connections and such that the battery modules are electrically coupled together in parallel. An interconnection electrically couples each stack of battery modules together via plug and receptacle connections with one of the battery modules in each stack such that the stacks of battery modules are electrically coupled together in parallel.

Described are mechanically robust, thermally managed battery module constructions including a battery case, a reinforcing divider in the case, and battery cells housed by the reinforcing divider. The reinforcing divider defines a plurality of thermal transfer elements externalized of the battery case. A shock dampening material can be provided between the reinforcing divider and the battery case to facilitate a mechanical, shock-dampened, reinforcing integration of the divider and case.

A riding lawn mower comprising, a pair of rear drive wheels, a pair of front wheels, a deck positioned between the pair of front wheels and the pair of rear drive wheels, a rotatable cutting blade, and multiple battery packs removably coupled to the riding lawn mower and structured to provide power to the riding lawn mower, each battery pack graspable and removable by a user, wherein the multiple battery packs sequentially provide power to the riding lawn mower.

A battery-powered motor may include an electric motor, a controller, and a housing. The electric motor may be wound to enable the battery-powered motor to achieve a non-limited motor maximum motor revolutions per minute (RPM) for at least one specified battery. The controlling current may include limiting current to the electric motor at lower RPMs, and limiting the current to prevent the RPM of the electric motor from exceeding a limited maximum motor RPM which is lower than the non-limited motor maximum RPM. The housing may enclose the electric motor and the controller and the specified battery. The housing may have a form factor to engage with a machine that engages with an internal combustion engine that has a maximum engine RPM that is approximately the same as the limited maximum motor RPM.
