As further scheme of the present utility model, described sensor comprises detection filter submodule, computing module, communication module and data memory module.Described detection filter submodule is connected with Amplifier Temperature A/D converter, voltage A/D converter, electric current A/D converter respectively.Described computing module is connected with described detection filter submodule, and described communication module is connected with described computing module, and described detection filter submodule, computing module and communication module are all connected with storer.
Compared with prior art, good effect of the present utility model is:
The utility model has function and concentrates, cost is low, the variation of signal output form, the advantage of function modoularization, battery condition can be predicted accurately and carry out failure self-diagnosis, protection accumulator, prevent over-discharge can, for the instrument that user vehicle provides a kind of warning in advance internal storage battery to damage, the probability that the vehicle that reduction automobile causes due to battery damage casts anchor, for car load factory provides a kind of car load power consumption control mode of the strategy that prestores, and a kind of method controlling generator is provided, thus realize car load energy management, reach the object reducing complete-vehicle oil consumption.
Accompanying drawing explanation
Fig. 1 is utility model works schematic diagram.
Embodiment
The utility model provides a kind of accumulator property detecting sensor, for making the purpose of this utility model, technical scheme and effect better clear, clear and definite, further describes the utility model referring to accompanying drawing.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and need not with restriction the utility model.
As shown in Figure 1, a kind of storage battery sensor, this storage battery sensor is arranged on automobile storage battery negative terminal, and the input end of storage battery sensor is connected with the negative pole wire harness of automobile, and the output terminal of storage battery sensor is connected with battery terminal negative.The signal output part of storage battery sensor is connected with demand controller.
