Description

Multi-loop charging system and its split battery pack

The invention provides a charging system for a multi-core battery pack, in particular, for each of the combined charging and discharging battery cells, which can be charged in an independent circuit to avoid potential problems of unbalance and overcharging.

It can be used for charging and discharging batteries from the early lead-acid batteries. Due to the development of various elements, there are many kinds of metal elements, such as lithium, antimony, chromium, aluminum and other composite elements. The single-cell battery, which is based on the existing elements, has a limited load pressure. Therefore, the operating voltage is between 2 and 3.7 volts. In order to increase the operating energy of the battery pack, most of the singles will be used. The core battery is combined in series to increase the output voltage. The multi-cell battery pack 1 shown in Fig. 1 is a combination of a plurality of charging and discharging batteries 10, and the single charging and discharging battery 10 is 3.7 volts. The working voltage, four series connected to the power output of 14.8 volts, and the charging must use a charging host 11 with a higher output voltage of 16V, after the voltage is converted by the AC power source 100, the multi-cell battery pack 1 The charging circuit is formed, and each charging and discharging battery 10 arranged in series is connected in series before and after the current path for synchronous charging, and the power state of the positive and negative poles of the multi-core battery pack 1 can be sensed by the detecting unit 12 in the system. After the full charge detecting unit 12 instructs the host computer 11 stops the charging.

However, most of the charging and discharging batteries 10 are used to form a multi-core battery pack 1. Since each of the charging and discharging batteries 10 is produced, its elemental composition cannot be absolutely equal or equal, which is a congenital problem of the charging and discharging battery 10. In the charging process, each charging and discharging battery 10 has different working reactions due to different composition and composition of the elements. When charging, the multi-core battery pack 1 is higher than the whole through a charging host 11 The charging voltage is 16 volts. Although the charging energy is divided equally between each charging and discharging battery 10 in series, the storage efficiency is different due to the uneven composition and quantity of each charging and discharging battery 10. The electrical reaction occurring in the charging and discharging battery 10 is also different, so that a part of the series of charging and discharging batteries 10 can obtain a higher voltage, and the charging current is unbalanced, and the charging and discharging efficiency of the part of the charging and discharging battery 10 is Relatively reduced or unable to quickly charge the power, the time course of charging is extended, causing the charging circuit to cause an unbalanced state, and the charging and discharging battery 10 full of electric energy is first, waiting for other insufficient charging and discharging batteries 10, the final result First full charge When the battery 10 is discharged, the overcharge is damaged. Therefore, in the charging process of the conventional multi-core battery pack 1, there is a common imbalance and overcharge phenomenon, which affects the life of the multi-core battery pack 1 as a whole, and the charging efficiency is slow.

The invention provides a charging system capable of independent loop charging, which mainly solves the problem of congenital potential power imbalance and overcharge of a conventional multi-core battery pack. The system is composed of a plurality of charging cells and combined into a multi-loop charging system. The output of a charging unit is composed of a positive circuit and a negative circuit to form a sorting contact. The positive circuit and the negative circuit in the sorting are collinear, and the adjacent collinear lines in the sorting can be respectively The independent circuit to which the charging unit belongs is the main purpose of forming multiple circuits for independent charging of multiple charging and discharging battery cells.

The second object of the present invention is to sort the positive electrode circuit and the negative electrode circuit, and form a sorting contact at the output end, and the sorting contact can be combined with an output connector via a cable to facilitate the charging operation.

A third object of the present invention is to provide a split-distribution battery pack in which each of the internal charge and discharge battery cells is independently charged and charged as an overall output split-range operation battery pack during charging.

The fourth object of the present invention is that the split-disc battery pack is composed of a plurality of charge and discharge battery cells before and after the positive and negative poles are connected in series, and is led out through the power wires at each series of contact points, and the power wires are combined for one meeting and meet. The electrical discharge constitutes a socket, which is a row of sockets such as serial terminals.
