Detachable battery case with casters for ultra-compact EVs (detachable from the side)

Abstract

Ultra-compact EVs are charged directly to the vehicle body using a dedicated cord, but in apartment buildings and other multi-unit housing, it is difficult to install extension cords in public corridors and on the walls of buildings.We provide a battery case for ultra-compact EVs that allows charging even in apartment buildings and other multi-unit housing. [Solution] This is an ultra-compact battery case 1 for EVs that allows the battery to be charged via an external charger from an outlet (100V and 200V (single-phase three-wire)) inside the home.It is a horizontally placed cube with five sides except the top surrounded by steel plates, casters 6 attached to the underside of the bottom, and an extendable handle 5 attached to the front.

Description

[Technical Field]

[0001] This invention developed a detachable battery case with casters that supplies power to the drive system and attached power system. [Background technology]

[0002] By creating and attaching a detachable battery case with casters that contains a built-in battery, it is possible to detach the entire battery case. Summary of the Invention [Problem to be solved by the invention]

[0003] Currently, ultra-compact EVs are charged using a dedicated cord that is directly connected to the vehicle itself, making it difficult to install extension cords in public corridors and on the walls of buildings in apartment complexes and other multi-unit housing, making charging impossible. [Means for solving the problem]

[0004] A removable battery case with casters and a built-in battery was created and installed. [Effects of the Invention]

[0005] By creating and installing a removable battery case with casters that contains a built-in battery, it is now possible to charge the battery in apartment buildings and other multi-unit housing by connecting it to an external charger from a 100V or 200V (single-phase three-wire) outlet for home use. [Brief explanation of the drawings]

[0006] [Figure 1] 1 is a representative diagram showing one embodiment of a detachable battery case with casters (detachable from the side) for a micro EV according to the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0007] The detachable battery case with casters for ultra-compact EVs (detachable from the side) forms a battery case that stores the battery inside and protects it with fixing belts and metal fittings. Casters are attached to the bottom of the battery case and a cart handle is attached to the right side. [Example]

[0008] An embodiment will be described below with reference to the accompanying drawings. 1 is a battery case made of steel, 2 is a metal fitting for fixing the battery, 3 is a belt fastener for fixing the battery, 4 is a belt for fixing the battery, 5 is a battery case handle, and 6 is a battery case caster.

Claims

[Claim 1] Currently, ultra-compact EVs are charged directly to the vehicle body using a dedicated cord, but in apartment buildings and other multi-unit housing, it is difficult to install extension cords in public corridors or on the walls of buildings, making charging impossible.However, by creating and installing a movable battery case (with casters) with a built-in battery inside the battery cover, it has become possible to attach and detach the battery case itself. Currently, the battery is located inside a battery cover under the driver's seat, and removal requires removing the driver's seat, the battery cover, and the battery fixing hardware before it can be attached or detached. However, with this invention, the detached battery can be directly charged in a movable battery case (with casters) that contains the built-in battery, and by connecting it to an external charger from a household 100V or 200V (single-phase three-wire) outlet, it can be charged even in apartment buildings and other multi-unit dwellings.
