Abstract
The utility model relates to a multi-functional automotive starting power supply unit, belonging to the technical field of automotive electrical equipment. The multi-functional automotive starting power supply unit comprises an original automotive starting assembly M and a generator G and has the function of capacitance energy storage. In the utility model, a high-capacity capacitor C is charged by an MCU (microprogrammed control unit) and a DC (direct-current)/DC conversion module. Furthermore, the charging voltage of the DC/DC conversion module is controlled according to a temperature sensor, and voltage signals of E1 and E2 ends of a storage battery, which are calculated by the MCU, so as to charge to a reasonable starting power. In the utility model, a dry battery emergency starting device is arranged. By adopting the multi-functional automotive starting power supply unit, the automotive starting property is improved, the discharging current of the storage battery is reduced, the service life of the automotive storage battery is prolonged, and the rationing capacity of the automotive storage battery is reduced by more than 3 times.
Description
Technical field
The utility model relates to multi-purpose vehicle(MPV) and starts electric supply installation, particularly a kind of automobile starting electric supply installation and method with capacitance energy storage.The utility model can improve the automobile starting performance, prolong automobile storage battery useful life, reduce the dispensing capacity of automobile storage battery.
Background technology
At present, automobile storage battery is used for a long time in the car electrics field.It is seriously polluted, volume is heavy, short-lived be well-known.Automobile storage battery can be with the delay of its service time, and performance index such as its capacity, internal resistance constantly descend.Its basic reason is to use due to the inclement condition, and heavy-current discharge, environment for use temperature effect etc. is changed once its average 2-3 in the automobile use.Storage battery becomes attrition component.
Different automobiles needs the transient current of 100-500 ampere starting moment.Will be equipped with the big electric current that jumbo storage battery provides startup to automobile starting with lead acid accumulator.Even be equipped with jumbo storage battery, but because the existence of accumulator internal resistance, voltage can drop to 8-10V when therefore causing startup.Influenced starting power output.According to the automobile operation principle, storage battery will change charged state into by power supply behind the automobile starting.It is equipped with jumbo purpose and just is used for starting.Can be equipped with the usefulness of low capacity storage battery so in start-up course, reduce the battery-operated electric current as automobile.Thereby save the lead ore resource and reduce the pollution of waste and old lead acid accumulator environment.
Current along with the development in science and technology of electronic component and the progress of manufacturing process.Large value capacitor is little with its volume, the life-span is long, discharging current is big and excellent properties such as environmental protection, and it is required just to be fit to automobile starting, utilizes its heavy-current discharge to reduce the heavy-current discharge of storage battery.Thereby can reduce battery capacity (storage battery can reduce 3-5 doubly) and reach to improve the automobile starting performance, prolong the automobile storage battery purpose in useful life.
The utility model content
The purpose of this utility model has been to overcome the deficiency of existing automobile lead acid accumulator, and a kind of raising automobile starting performance is provided, and the multi-purpose vehicle(MPV) that reduces automobile storage battery dispensing capacity and take into account emergency starting starts electric supply installation.
The alleged problem of the utility model realizes with following technical proposals:
A kind of multi-purpose vehicle(MPV) starts electric supply installation, be to constitute by control unit MCU (1), high capacity capacitor C (2), current-limiting resistance R (3), DC conversion modules DC/DC (4), temperature sensor T (5), storage battery E1 (6), dry cell box E2 (7), indicating device LED (8), alternator assembly G (9), starter motor assembly M (10) and K switch parts (11), the work of this device is controlled by MCU in its inside, and can be according to Monitoring Data by calculation control charging, discharge and unusual LED indication.
The utility model is to utilize large value capacitor to provide the startup electric energy for automobile starter assembly M.Utilize the heavy-current discharge output characteristic of high capacity capacitor C, effectively raise the automobile starting electric current, increased automobile starting power.Reduce the rush of current of big electric current, prolonged storage battery useful life storage battery.

Fig. 1 is that system's connection layout, Fig. 2 are control unit figure.
Embodiment
The utility model charges to high capacity capacitor C by control unit MCU and DC conversion modules CD/CD.And can calculate the charging voltage that DC conversion modules CD/CD is controlled in the back through MCU according to the voltage signal of temperature sensor T temperature, circuit 1,2,4 ends, to reach rational starting power.MCU controls the DC conversion modules CD/CD reduction charging current prolongation charging interval at this moment when storage battery E1 voltage is lower than its rated voltage U1, and E1 protects to storage battery.MCU controls DC conversion modules CD/CD at this moment and stops using storage battery E1 as charge power supply when storage battery E1 voltage is lower than its limiting voltage U2, and by circuit 8 output actuation indicator LED flicker alarms, prompting uses standby dry cell box E2 as charge power supply.Annotate: the technical indicator that U1, U2 provide for the battery manufacturer man.The utility model is by behind the automobile starting, and alternator assembly G charges to storage battery.
Claims (2)
1. a multi-purpose vehicle(MPV) starts electric supply installation, it is characterized in that, it is made of control unit MCU, high capacity capacitor C, current-limiting resistance R, DC conversion modules DC/DC, temperature sensor T, storage battery E1, dry cell box E2, indicating device LED, engine assembly G, starter motor assembly M and starting switch K parts, the work of this device is controlled by MCU in its inside, and can be according to Monitoring Data by calculation control charging, discharge and unusual LED indication.
