Automobile-used startup power supply

  

Technical field

The present invention relates to a kind of automobile-used startup power supply.

Background technology

Automobile generally enters into each family, and how the environmental pollution also having brought in the quality of life that has improved people reduces toxic emission and the large problem of saving the energy and just become today.

Generally do startup power supply with lead acid accumulator at present, under heavy-current discharge, change in voltage is large, and while causing starting, oil consumption is high; Lead acid accumulator can not normally start at lower than-20 ℃ of temperature; When existing startup Power Management Design, lead acid accumulator does not have Cross prevention function, spends the night and electric weight is given out light when car light does not close, and automobile need to start by external power source.

Ultracapacitor and superbattery have large current discharging capability under fabulous High-current output ability, especially low temperature, are suitable for automobile starting power supply, but its storage power is few, can not meet the requirement of vehicle power consumption.

Automobile starting power supply is lead acid accumulator substantially at present, and service life of lead accumulator is short, needs to change in 1, two year, producing and using in lead acid accumulator, environment is had to pollution simultaneously; Lead acid accumulator High-current output ability, change in voltage is large, causes starting oil consumption higher, automotive electronics circuit stability is had to impact simultaneously; Lead acid accumulator poor performance at low temperatures can not normally start below-20 ℃; Existing startup lead acid accumulator, does not have Cross prevention, and after forgetting that closing car light spends the night, lead acid accumulator was prone to be put, and damage battery life needs to borrow external power source could again start automobile simultaneously.

The technological deficiency existing: in the time that batteries electric weight is finished, cannot automatically realize normal restarting.

Summary of the invention

Cannot realize restarting, deficiency that reliability is lower for what overcome existing automobile-used startup power supply, the invention provides a kind of restarting, good automobile-used startup power supply of reliability effectively realized.

The technical solution adopted for the present invention to solve the technical problems is:

A kind of automobile-used startup power supply, comprise the first power supply and batteries, described the first power supply is the power supply with large current discharging capability, the positive pole of described the first power supply is connected with the positive pole of described batteries, the negative pole of described the first power supply is connected with the negative pole of described batteries, described batteries is connected with residual capacity measurement module, described batteries and current-limiting circuit, controlled switch series connection, described controlled switch with in order to turn-off described controlled switch and be connected when the restarting control module of receiving closed described controlled switch after vehicle launch signal in the time that dump energy be less than setting threshold.

In the present invention, turn-off described controlled switch in the time that dump energy is less than setting threshold, batteries stops output current, and when receiving closed described controlled switch after vehicle launch signal, the action of restarting control module, Xu electricity Chi Zu Give the first power source charges, realizes restarting.

Further, described batteries is capacity type or power-type lead-acid battery group.

Or: described batteries is capacity type or power lithium battery group.

Further, described the first power supply is super capacitor module or superbattery group; Certainly, also can there is for other power lithium battery group of large current density power.

In described the first power module, each ultracapacitor or superbattery monomer are in parallel with voltage balance circuit.

Described batteries 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 are integrated on charge-discharge protection circuit plate.

Technical conceive of the present invention is: a ultracapacitor or superbattery storage battery in parallel, and wherein ultracapacitor or superbattery all have High-current output ability, and starting current is provided, and storage battery provides vehicle power consumption.Storage battery can be capacity type or power lithium battery and lead-acid battery.

Storage battery is with discharge protection circuit, and in the time that battery tension reaches protection value, protective circuit is cut off battery discharging loop; When lock reopens, protective circuit is recovered, and the remaining capacity of storage battery, to super capacitor module or superbattery group momentary charge, is realized restarting.

Super capacitor module or superbattery group have individual electric voltage equalization protective circuit.

Beneficial effect of the present invention is mainly manifested in: realize fast restarting, promoted startup unfailing performance.

Accompanying drawing explanation
