Technical field
The present invention relates to a kind of automobile-used startup power supply。
Background technology
Automobile generally enters into each family, the environmental pollution also brought while the quality of life that improve people, how to reduce toxic emission and has just become the big problem of today with the saving energy。
General lead-acid accumulator does startup power supply at present, and under heavy-current discharge, change in voltage is big, and when causing starting, oil consumption is high;Lead-acid accumulator can not normally start at lower than-20 DEG C of temperature;During existing startup Power Management Design, lead-acid accumulator does not have Cross prevention function, overnight and by electricity gives out light when car light does not close, and automobile needs to start by external power source。
Ultracapacitor and superbattery have fabulous High-current output ability, especially large current discharging capability under low temperature, be suitable for automobile starting power supply, but it stores little energy, it is impossible to meet the requirement of vehicle power consumption。
Current automobile starting power supply is substantially lead-acid accumulator, and service life of lead accumulator is short, needs to change in 1, two year, simultaneously producing and using in lead-acid accumulator, environment is had pollution；Lead-acid accumulator High-current output ability, change in voltage is big, causes starting oil consumption higher, electrical automotive circuits stability is had impact simultaneously；Lead-acid accumulator poor performance at low temperatures, can not normally start below-20 DEG C；Existing startup lead-acid accumulator, it does not have Cross prevention, after forgetting that pass car light is overnight, putting easily occurred in lead-acid accumulator, and damaged battery life, simultaneously need to borrow external power source just can be again started up automobile。
The technological deficiency existed: when accumulator battery electricity is finished, it is impossible to be automatically obtained normal restarting。
Summary of the invention
Cannot realize, in order to what overcome existing automobile-used startup power supply, the deficiency that restarting, reliability are relatively low, the invention provides and a kind of effectively realize the automobile-used startup power supply that restarting, reliability are good。
The technical solution adopted for the present invention to solve the technical problems is:

In the present invention, when dump energy turns off described controlled switch less than when setting threshold value, accumulator battery stops output electric current, and after receiving vehicle launch signal, close described controlled switch, restarting controls module action, accumulator battery the first power source charges, it is achieved restarting。
Further, described accumulator battery is capacity type or power-type lead-acid battery group。
Or: described accumulator battery is capacity type or power lithium battery group。
Further, described first power supply is super capacitor module or superbattery group；It is of course also possible to there is the power lithium battery group of large current density power for other。
In described first power module, each ultracapacitor or superbattery monomer are in parallel with voltage balance circuit。
Described accumulator battery is connected with charge and discharge protecting module。
Preferably, described residual capacity measurement module, restarting control module and charge and discharge protecting module are integrated on charge-discharge protection circuit plate。
Or: described residual capacity measurement module, restarting control module, voltage balance circuit and charge and discharge protecting module and are integrated on charge-discharge protection circuit plate。
The technology of the present invention is contemplated that: ultracapacitor or a superbattery accumulator in parallel, wherein ultracapacitor or superbattery are respectively provided with High-current output ability, it is provided that starting current, and accumulator provides vehicle power consumption。Accumulator can be capacity type or power lithium battery and lead-acid battery。
Accumulator is with discharge protection circuit, when battery tension reaches protection value, protects circuitry cuts battery discharging loop;When lock reopens, protection circuit recovers, and the remaining capacity of accumulator is to super capacitor module or superbattery group momentary charge, it is achieved restarting。
Super capacitor module or superbattery group have individual electric voltage equalization protection circuit。
Beneficial effects of the present invention is mainly manifested in: quickly realize restarting, improves startup unfailing performance。
