Abstract
A kind of quick super capacitor automobile auxiliary actuator suitable for low temperature, is made of super capacitor group, dcdc converter, super capacitor electronic control unit ESU.The end the B+ of starter, B- is connect with the positive and negative anodes of battery pack respectively.The end S+ of starter connects with the end S+ of starter.Super capacitor automobile auxiliary actuator takes electricity to complete the charging to super capacitor from battery, and storage battery energy is transferred in supercapacitor by realization, on startup, instantaneous super-large current demand is provided only by super capacitor.System replacement battery uses super capacitor as across-the-line starting power supply as direct startup power supply.Since super capacitor internal resistance is small, calorific value is small after single starting, improves the utilization rate of the energy content of battery, ensure that the service life of battery.Applied to multiple, frequent, cold-starting occasion.
Description
Technical field
It assists completing automobile starting at low temp the utility model relates to a kind of starter, belongs to automobile technical field.
Background technique
With the development of new energy, battery occupies indispensable important function energy resource system.Automobile industry,
Crane, agricultural equipment in weapon armoured equipment, generally use battery as starter auxiliary power supply, so in energy resource system
And the method times so has the following problems and disadvantage: cannot achieve reliable high current starting, although the increase of current battery C number
It can be realized heavy-current discharge, but the impact of long-time transient current will seriously affect battery life, reduce the increase of its reliability
Maintenance.Battery still cannot achieve low temperature environment starting, and battery low-temperature characteristics is very poor, especially in the north or winter situation
Under, the starting frequency of failure increases.In certain occasions, starter frequent starting, such as portainer, Shock vehicle are needed
Deng battery is equally unable to satisfy the demand of frequent starting.
Summary of the invention
To solve the above problems, the utility model provides a kind of auxiliary actuator based on super capacitor, DCDC is used
By taking electricity from battery, it is stored in super capacitor, completes the starting to starter using super capacitor.Its object is to energy
Enough realize automobile low temperature, quickly, reliable, frequent starting demand, to make up the low integrity problem of start battery system.
Purpose of the utility model is realized as follows:
Super capacitor automobile auxiliary actuator is by super capacitor group, dcdc converter and super capacitor electronic control unit
Composition.Wherein it is electrically operated can to complete charge and discharge under low temperature (- 40 DEG C) for super capacitor, and DCDC, which is mainly realized, turns accumulator electric-quantity
It changes in super capacitor, realizes super capacitor fast charging.Super capacitor electronic control unit mainly fills super capacitor group completion
Electric strategy, balance policy, super capacitor Preservation tactics and cold-starting strategy are realized.Super capacitor starter access automobile opens
Electricity is taken from battery pack after dynamic system, and battery pack is replaced to power to starter, it is straight relative to traditional capacitance group and battery pack
For connecing parallel system, the utility model super capacitor and battery pack belong to fallback relationship, during startup, only by super
Grade capacitor provides instantaneous super-large current demand.So as to avoid in parallel system, while electricity is extracted from battery and capacitance group
The case where stream, allows battery pack to obtain more reliable protection.The intelligent control of combining super capacitor electronic control unit, real-time ensuring are super
Capacitance voltage platform and energy, enough starting next time demand.Calorific value is small after super capacitor internal resistance simultaneously is small, single starts,
To improve the utilization rate of electric energy, and multiple frequent starting can be completed.
Since the utility model independently replaces the topological structure mode of battery pack, capacitance group and battery using super capacitor group
Group directly carries out power conversion using DCDC.It is opposite topological with super capacitor group and the direct parallel system of battery pack, have higher
Reliability, can be realized low temperature, quickly, frequently start demand, and improve utilization rate of electrical.
