Description
Technical field
The utility model relates to a kind of battery combination technology, relates in particular to a kind of battery modules.
Background technology
Current, battery modules is extensive use.For example, just adopted battery modules on the hybrid vehicle, its battery modules combines with motor and can reach the purpose that reduces environmental pollution and reduce oil consumption.
See also Fig. 4, traditional battery modules 1` comprises some series connected battery groups, and each battery pack comprises the battery 10` of some parallel connections.
Yet above-mentioned battery modules 1` is because of the battery parallel connection in the battery pack, so unless the battery in the battery pack occur simultaneously unusually, thereby otherwise having battery to occur being difficult in time find to make troubles when unusual to maintenance.
The utility model content
Main purpose of the present utility model is to provide a kind of at the defective that the above-mentioned background technology exists to have battery to occur can be convenient to when unusual the battery modules of in time finding.
For achieving the above object, the battery modules that provides of the utility model comprises a self-contained battery device, some battery pack and at least one battery protecting circuit module.The self-contained battery device comprises a positive conductive plate and a negative conductive plate.Each battery pack has some series connected battery, and described some battery pack are connected in parallel between positive conductive plate and the negative conductive plate.The battery protecting circuit module has some signal connection ends, and the positive and negative electrode of described each battery electrically connects with a signal connection end of this battery protecting circuit module respectively.
As mentioned above; the utility model battery modules forms battery pack by the battery series connection; some battery pack are in parallel again and be arranged between positive conductive plate and the negative conductive plate; the positive and negative electrode of each battery electrically connects with a signal connection end of battery protecting circuit module respectively; thereby when there being battery to take place when unusual in the battery pack; the battery protecting circuit module can in time detect unusual battery according to the variation of electric current and voltage, thus convenient for maintaining.

Embodiment
For describing technology contents of the present utility model, structural feature, the purpose of being reached and effect in detail, below exemplify embodiment now and conjunction with figs. is described in detail.
See also Fig. 1, Fig. 2 and Fig. 3, the utility model battery modules 1 comprises a self-contained battery device 10, some battery pack 20 and some battery protecting circuit modules 30.Self-contained battery device 10 comprises by the uniform nickel sheet metal of material to be made and roughly is a rectangular tabular positive conductive plate 11 and a negative conductive plate 12.Positive conductive plate 11 is parallel with negative conductive plate 12, one end of positive conductive plate 11 protrudes out one and is used for the columniform anodal joint pin 13 that is connected with the external circuit (not shown), and an end of negative conductive plate 12 protrudes out one and is used for the columniform negative pole joint pin 14 that is connected with the external circuit (not shown).The end that positive conductive plate 11 is provided with anodal joint pin 13 is relative with the end that negative conductive plate 12 is provided with negative joint pin 14.Anodal joint pin 13 is that a symmetry discharges and recharges a little in order to increase the efficiency for charge-discharge of self-contained battery device 10 with negative pole joint pin 14.
The positive and negative electrode butt of the adjacent cell 21 of described some battery pack 20 (formation series relationship) and each battery 21 linearly formula are arranged, and each battery pack 20 is connected between positive conductive plate 11 and the negative conductive plate 12 in parallel to each other.The resistance that positive conductive plate 11 and negative conductive plate 12 are distributed on each battery pack 20 equates that the electric current that flows through on each battery pack 20 equates, the charging interval is consistent thereby make easily.Battery 21 in the described battery pack 20 can be lithium battery.
Described some battery protecting circuit modules 30 respectively with a battery pack 20 corresponding settings, each battery protecting circuit module 30 all has some signal connection ends.The positive and negative electrode of each battery 21 of battery pack 20 is electrically connected to a signal connection end of battery protecting circuit module 30 respectively; thereby battery protecting circuit module 30 can detect the electric current and the voltage of each battery 21; when having battery 21 generations unusual in the battery pack 20, battery protecting circuit module 30 can in time detect unusual battery 21 according to the variation of electric current and voltage.
In sum; the utility model battery modules 1 forms battery pack 20 by battery 21 series connection; some battery pack 20 are in parallel again and be arranged between positive conductive plate 11 and the negative conductive plate 12; the positive and negative electrode of each battery 21 electrically connects with a signal connection end of battery protecting circuit module 30 respectively; thereby when having battery 21 generations unusual in the battery pack 20; battery protecting circuit module 30 can in time detect unusual battery 21 according to the variation of electric current and voltage, thus convenient for maintaining.
