Abstract

A battery swap system for electric cars is disclosed. The battery swap system is based on two identical semi-cylindrical batteries which once attached to each other create solid rotatable cylinder along its axis. The battery swap system includes a battery housing for fast battery swap in electric cars or other electric vehicles. The battery housing serves to anchor one single semi-cylindrical battery. The housing has multiple rails along its perimeter. The battery has multiple grooves relating housing rails. The battery swap system enables smooth rotation movement with instant battery anchoring into the housing. The cylinder system moves about 180° along its axis for full battery swap.

Description

Battery swap system
FIELD OF THE INVENTION
The present invention relates to electric cars. More particularly, the present invention relates to the battery swap at designated swap station. Present invention offers fast and simple battery swap that makes an electric car more comfortable for the car user.
BACKGROUND OF THE INVENTION
Electric cars require specific power management. When the battery is expended, it must be either recharged or replaced. Charging process may introduce considerable delay for the car user, or can be uncomfortable because of charging point access on the street. Current battery swap stations operate in two stage process. Firstly the exhausted battery must be removed and secondly the fully charged battery must be installed. Battery swap systems require precise car alignment, adequate hoisting mechanism and random storage systems. Overall process of current battery swap is time demanding and require more mechanical systems in comparison with the present invention.
Swapping of batteries in case of electric cars provide considerable advantages against recharging the electric car from the electrical grid with plug. Battery swap is fast. Battery charging is controlled at the swap station. There is no risk of charging at low or high temperatures. Charging at the station intelligently use low rate power resulting in cheaper energy for the car user. Controlled charging of mass number of batteries for electric cars mitigates overloading of the grid.
SUMMARY OF THE INVENTION
The present invention is generally directed to a battery system in pure electric cars and similar vehicles. Battery system enables a car user to change exhausted battery with a fully charged one within 10-20 seconds. Therefore, a battery swap system described in this article represents easy and very fast one stage changing process. The invention describes the shape of removable battery, its housing which is tightly mounted in the lower part of an electric car, the process of the battery swap based on battery rotation along its axis about 180°. The shape of the battery is a semi-cylinder. Aligning of two batteries creates a full cylinder which can be easily rotated. Thus a rotation about 180° will remove the exhausted battery from the housing and simultaneously install the fully charged battery into the housing. The battery swap process require just one travel of battery carrier to the battery housing, which minimizes the time demand for battery swap. It also mitigates the need of mechanical equipment of the swap mechanism, which is a part of the swap station.

DETAILED DESCRIPTION OF THE DRAWINGS
Referring initially to FIGS. 1-9 of the drawings, an illustrative embodiment of the battery swap system is generally indicated by numbers.
As illustrated in FIG. 1, an electric car 1 has the integrated battery system 2 in the center of the vehicle. FIG. 2 shows an electric car 1 and position of the integrated battery system 2 viewed from the side.
As further illustrated in FIG. 3, a battery system consists of a battery housing 3 and battery 4. A battery housing is fixed to a car body while battery is removable. Referring next to FIGS. 4, 5, 6 key elements of the battery system will be described. A battery housing 3 consists of a shell 5 of semi-cylindrical shape. The housing shell 5 must be hardly fixed to the car body using anchoring blocks 6 with bolts. The housing shell includes anchoring rails 7 which correspond to anchoring groves 12 on the battery body 4. The shell 5 serves for electrical power transfer between the electric car 1 and the battery 4. For the power transfer there are two rods: plus rod 8 and minus rod 9 incorporated into the second anchoring rail 10. Rods are further connected to the electric car with cables (not shown). The second anchoring rail 10 includes a connection pin 11, which downloads and transfers the data between the battery and the electric car. Typical data summarize ID of the battery, current energy value, estimated range and error messages.
The battery 4 as illustrated has a semi-cylindrical shape. Battery 4 consists of rigid carrying cage 13 which holds the volume filled with battery cells 14. Surfaces between carrying cage elements are tightly sealed with plastic sheets 15. The carrying cage includes a mechanical system that enables the rotation of the battery, in front end and rear end 16 of the battery there is a negative semi-cogwheel 17. There is a center semi-pin 18 attached to both front and rear negative cogwheels. The profile of the negative cogwheel and center pin is slightly tapered outwards which serves for precise aligning of two identical semi-cylindrical batteries so it creates one rotatable cylinder. The carrying cage 13 provides anchoring of the battery 4 to the battery housing 3 with anchoring grooves 12 along the perimeter of the battery. The second anchoring groove 19 includes contactors with plus polarity 20 and minus polarity 21 for power transfer to plus rod 8 and minus rod 9 in the battery housing 3, and also a contractor pin 22 for data transfer via connection pin 11. Two leading cogwheels 28 are parts of the battery loader 27 and serves for connecting two batteries and for rotating batteries.
FIG. 7 refers to the battery swapping process. FIG. 7a shows an electric car 1 arriving at the swap station 23, stopping according to signalization at the swap station 23. The car is roughly aligned. In this stage the exhausted battery 24 in the battery housing 25 and fully loaded battery 26 ready in the battery loader 27 are almost above each other. For proper alignment of both battery packs the battery loader 27 must be equipped with micro adjustment for rear-front and left-right direction. Proper alignment is dedicated using sensors. Once both battery packs are aligned properly the swapping process can start. As shown on the FIG. 7b the battery loader 27 hoists the fully loaded battery 26 so it is attached to the exhausted battery 24 mounted in the battery housing 3 and together it creates a full cylinder rotatable object. FIG. 7c shows the rotation of connected batteries about 180° for one full battery swap. FIG. 7d shows the termination of the swapping process. Fully loaded battery is now fixed in the battery housing, the exhausted battery descents on the battery loader under the floor. The car is now ready to go out of the station. The exhausted battery is shifted further in the underground random storage 25 while other fully loaded battery is fitted onto the battery loader 27.
FIG. 8 refers to aligning of two batteries to create a rotatable cylinder according to the swapping process in the FIG 7b. FIG. 8a shows the battery loader 27 hoisting the fully loaded battery 26 so it aligns to the exhausted battery 24. Rear and front cogwheel 28 mounted on the battery loader 27 are still in open position. FIG. 8b shows rear and front cogwheel both pressing toward aligned batteries and entering into both negative cogwheels which are part of the battery. Tapering of the cogwheel and negative cogwheel enables smooth and precise aligning. The full rotatable cylinder composed by two semi-cylindrical batteries is ready to be rotated.
FIG. 9 shows the battery loader 27 hoisting the fully loaded battery 26 so it aligns to the exhausted battery 24.
