Automotive electrical system of the present utility model does not influence the normal operation of other electricity consumption devices in the car when engine starting; Can guarantee the service life of storage battery, improve the reliability of battery component; Can also realize more engine starting-shutdown number of times, reduce oil consumption to a greater extent.
In addition; after using of the present utility model pair of battery electrics electric system; except basic automatic engine stop-autostart function; electric system can also provide braking energy to reclaim and slight assist function; so just may reclaim the waste of power of the glancing impact that disappears; save more fuel oil, under urban traffic situation, can improve fuel economy about 10%.
Description of drawings
Describe automotive electrical system of the present utility model in detail below in conjunction with accompanying drawing, wherein:
Fig. 1 is the scheme drawing of the automotive electrical system of the utility model use.
The specific embodiment
As shown in Figure 1, automotive electrical system of the present utility model comprises other electricity consumption devices 17 in starter motor 10, starting type accumulators 12, electric system controller 14, electrical generator 16, power supply type storage battery 18 and the automobile.
Composing in parallel with described starter motor 10 of described starting type accumulators 12 starts the loop; Described power supply type storage battery 18, electrical generator 16 compose in parallel the current supply circuit similar to general-utility car to other electricity consumption devices 17; Described electric system controller 14 is connected between described startup loop and the described current supply circuit.
Preferably, automotive electrical system of the present utility model also comprises DC/DC DC converter 15, this DC/DC DC converter 15 and described electric system controller 14 are connected between described startup loop and the current supply circuit, thereby so that filter the quality of the ripple raising auto electric network in the electric system.
Preferably, described starting type accumulators 12 is made by super capacitor (perhaps being called electrochemical double layer electric capacity).Super capacitor itself is the power-type device, even frequent high current charge-discharge, its service life and reliability also can meet design requirement.Starting type accumulators 12 only is used for to starter motor 10 power supplies in the utility model, when driving engine started automatically, starting type accumulators 12 discharged big current drives starter motor 10 at short notice, after starter motor 10 takes driving engine to certain rotating speed, the vehicle launch process is finished in driving engine oil spout igniting.When car brakeing, reclaim by control energy, give starting type accumulators 12 electric energy supplement, the driving engine that is used for next time starts automatically.It will be understood by those skilled in the art that the functional unit that control energy reclaims is not the place of improvement of the present utility model, therefore do not do here and give unnecessary details.The utility model also can use vehicle-borne electrical generator 16 to be described starting type accumulators 12 electric energy supplement.
