Detailed Description

In order to better explain the present invention, the detailed description of the invention is made below with reference to the accompanying drawings and specific embodiments.

The specific embodiment is as follows: see fig. 1-3.

This embodiment, a group battery that is used for new forms of energy car to arrange formula in parallel to charge, includes a plurality of battery module that set up side by side, as shown in fig. 1, 2, 3, be two modules of battery module A and battery module B in the broken line frame respectively, and every battery module divide into a plurality of charging modules, and in the figure, A, B has contained four charging modules respectively, A promptly₁、A₂、A₃、A₄And B₁、B₂、B₃、B₄. Each charging module A₁、A₂、A₃、A₄、B₁、B₂、B₃、B₄Comprises a battery pack formed by connecting a plurality of batteries in series and/or in parallel, and the battery packs are integratedThe module structure shown in the figure leads out the charged cable and the charging interface from the positive and negative poles of the battery pack in each battery module.

The surface of the battery module is distributed with discharging contacts, and the discharging circuit and the charging circuit are separately arranged.

Fig. 2 is a circuit diagram of the battery pack of fig. 1. In FIG. 2A₁、A₄、B₂、B₃Each form an independent charging circuit from the positive electrode and the negative electrode of the battery pack through an external cable, and A₂B₁、A₃B₄After the connection, the positive pole and the negative pole of the battery pack after the connection form independent charging circuits through external cables. The charging group of the embodiment forms six parallel cables in total, and can be connected with six charging devices simultaneously.

Fig. 3 is a circuit diagram of a charging cable and a charging interface, wherein six parallel cables are respectively connected with a metal rod and a bottomless metal barrel-shaped structure, and are wrapped and isolated by an insulating material, the charging interface is designed into a column shape, the external material of the charging interface is an insulator, and three rows of charging metal rods are wrapped inside the charging interface. The upper and lower rows are respectively A₁、A₄、B₂、B₃The charging interfaces are respectively connected with 5KW charging connectors, and one row in the middle is A₂B₁、A₃B₄The charging connectors of (1) are respectively connected with 10KW charging connectors, and the total power of the used matched total external charging connectors is 40 KW.

The charging electric wire circuits are used for a column type or row type charging interface, two column type or row type charging interfaces are formed by two identical charging electric wire circuits, and the charging electric wire circuits are used for safer and faster charging. The method and the process for charging the new energy vehicle by adopting the parallel row type charging group of the new energy vehicle in the embodiment are as follows:

the new energy vehicle is provided with a plurality of groups of charging interfaces, and each charging interface is matched with the external charging connector.

The charging mode is divided into a common charging mode and a quick charging mode, the common charging mode is to charge the new energy vehicle by using one column type or row type charging interface, and the quick charging mode is to quickly charge the new energy vehicle by simultaneously inserting three column type or row type charging interfaces.

Because a column charge head or a row of the head that charges is followed by six parallel cables, the power requirement of the charging device that every charging cable allies oneself with is less than or equal to 10 KW.

If a column type or row type charging interface is used, the design rather divides the single-path charging into six paths of parallel row type charging, and the charging device is connected at the same time, so that the power requirement on a charging circuit connected with a single-path charging cable (single gun) is reduced, and the charging safety is facilitated.

If three column type or row type charging interfaces are used, the design rather divides single row charging into three rows of parallel charging, and the charging device is connected at the same time, so that the power requirement on a charging circuit connected with a single row charging cable (single gun) is reduced, and the quick charging safety is facilitated.

A new energy vehicle battery pack is provided, wherein the battery capacity of each battery module is 16 KW.h, the total battery capacity of the double battery modules is 32 KW.h, for example, the battery pack is based on the electricity charged to 80 percent (the charging amount of a lithium battery is in direct proportion to the charging time before the lithium battery is charged to 80 percent), after 80 percent, the charging amount of the lithium battery is not in proportion to the charging time and is in a trickle maintenance stage, namely, the charging amount is the condition 1), the charging amount of 80 percent is 25.6 KW.h, for example, the distance of the new energy vehicle driving to 7 kilometers per KW.h is the condition 2, a parallel row type charging method is adopted, a row of parallel charging interfaces or a cylindrical charging interface is adopted, the external charging power is 40KW, the time required for estimating the electricity charged to 80 percent is about T ═ 25.6 ÷ 40 × 60 ═ 38.4min, and the battery pack can continue driving for about 25.6 × 7 ═.

The battery capacity of each battery module is 16 KW.h, the total battery capacity of the double battery modules is 32 KW.h, the battery is charged to 80% of electricity as a standard (before the lithium battery is charged to 80% of electricity, the charging amount of the lithium battery is in direct proportion to the charging time, after 80%, the charging amount of the lithium battery is not in proportional relation to the charging time, the situation after the lithium battery is charged to 80% is not considered), the charging amount of 80% is 25.6 KW.h, the new energy vehicle existing in the market can travel 7 kilometers per KW.h of electricity, three rows of parallel charging interfaces or three cylindrical charging interfaces are adopted, the external charging power is 40KW, externally matched 3 cylindrical cable type row type charging connectors or 3 cable type charging connectors are used, the time required for charging to 80% of electricity is T ═ 25.6 ÷ 40 ÷ 3 × 60 ÷ 12.8min, and the new energy vehicle can travel about 180 kilometers.

The method and the process for charging the new energy vehicle by adopting the battery pack for charging the new energy vehicle in parallel rows are as follows:

the charging mode is divided into a common single charging mode and a parallel charging mode, the common single charging mode is to charge the new energy vehicle by adopting a single charging head, and the parallel charging mode is to charge the new energy vehicle in parallel by adopting a row-type charging head.

The external charging connector is matched with a male and female type of an on-vehicle charging interface. During charging, a parallel charging mode is selected on the human-computer interaction interface to charge the new energy vehicle, and the rest processes are the same as or similar to those of a single charging mode.

In summary, according to the charging method for the parallel-row type battery pack of the new energy vehicle, charging current, voltage and power are suppressed by charging the battery pack in different regions and in parallel rows, and the charging risk of high current, high voltage and high power is solved.

By increasing the number of the battery modules, the charging efficiency can be possibly improved, scientists and engineers in the field can enable the number of the battery modules of the new energy vehicle in the future, and the curve of the charging efficiency and the time to accord with the moore law (because of the size relation, the charging efficiency is not a computer chip) and is similar to the phenomenon of a transistor of a central processing unit of a computer.

The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and it will be apparent to those skilled in the art that various changes and modifications can be made, or other related technical fields can be applied, without departing from the spirit of the present invention, and all such changes and modifications are encompassed in the scope of the present invention.
