Description
Technical field
The utility model relates to the auto parts and components field, specifically is a kind of automobile auxiliary starting device.
Background technique
The starting of motor car engine at present all is the start mode (abbreviation starter motor) that adopts starting motor basically, and starter motor is by the lead-acid battery powered operation, and can lead-acid battery working properlyly be one of key point of car engine start.
The main cause of engine start difficulty has:
1) lubricating oil viscosity increases, and mobile variation makes fuel feeding deficiency between each rubbing surface to form semi-dry friction or dry friction, has increased the resistance to motion between rubbing surface, makes the starting resistance square increase.
2) viscosity of fuel oil and density all increase, mobile variation, atomization badness, prolonged ignition delay period, the air temperature that enters cylinder simultaneously is low, and parts such as cooling liquid, cylinder liner, piston will absorb more heat at work, have increased thermal loss, the temperature of engine mixed gas is reduced, and combustion condition is abominable.
3) the internal resistance increase of battery liquid and viscosity increase, and descend to the pole plate penetrating power, and pole plate internal layer active substance can not make full use of during discharge, and output capability reduces greatly, causes the unable motor that drags of starter motor to reach minimum starting speed.
Automobile cold start is original just to need bigger starting power, but storage battery output capability at low temperatures significantly reduces.In order to guarantee the automobile normal starting, require automobile power system can provide enough energy, make motor reach minimum starting speed, the mode that is parallel with super capacitor is also arranged at present, but all fundamentally do not address this problem, the method that has is also wanted the energy of battery consumption on the contrary.
Summary of the invention
The purpose of this utility model is in order to continue the motor of start-uping a car at low temperature and other rugged environment, to propose a kind of automobile auxiliary starting device.
The technical solution of the utility model is for this reason: the automobile auxiliary starting device, comprise in the starting arrangement loop and be parallel with super capacitor C1 and cranking-motor relay RL2 by storage battery E1, it is characterized in that: in the loop of starting arrangement, be provided with the control module ECU that boosts, the ECU input end be connected with control switch K4 to battery main switch K3 to storage battery E1 positive pole, ECU control output signal end is in series with output relay switch RL1 to super capacitor C1 positive pole; On the key operation ON shelves that the charging control signal of ECU is received by charge switch K2, ECU working state control signal by ignition switch K1 to storage battery E1 positive pole.
Improvement to such scheme is: wherein control switch K4, charge switch K2 and output relay switch RL1 are mechanical switch or electronic switch.
Beneficial effect:
A kind of new vehicle starting power solution that the utility model proposes; On the basis of original storage battery, increase a kind of novel energy-storing device super capacitor, in the loop of starting arrangement, be provided with control module ECU; By control module ECU, make super capacitor carry out boost charge to storage battery, after process to be charged finishes, carry out auxiliary starter according to default control logic again.
In order to give full play to the energy storage effect of super capacitor, not simply super capacitor to be connected in parallel on the storage battery two ends.In order to increase the electric capacity energy stored, improve the charging voltage of electric capacity.Under the condition of electric capacity constancy of volume, to adopt to include the ECU control module, control is boosted (comprising the DC/DC booster circuit) when the terminal voltage of electric capacity is brought up to 36V by 24V, because P=CU
2/ 2, so the energy storage capacity of electric capacity has improved 2.25 times, the capacitor discharge ability obviously strengthens.
Used after this device, because the equivalent internal resistance of super capacitor is far below the internal resistance of storage battery, especially after having used control and boost module, the energy of super capacitor storage is increased greatly, when automobile is in state of starting operating, according to logic of propositions in the suitable moment, super capacitor will power supply as starter motor in parallel with storage battery, both satisfied the enough big electric current and the voltage of starter motor needs, enough effective starting powers also be provided, make pilot engine easier; Simultaneously because under general user mode, super capacitor can be directly parallel in the two ends of storage battery, therefore can effectively improve the big electric current instant response characteristic of automobile power system (motor+storage battery+super capacitor), effectively absorb surge simultaneously, improve the electrical environment of car load greatly, reduce the damage of vehicle electronics electrical products, improve the working life of storage battery.
The starting effect that the storage battery that the utility model can make the storage battery of littler ampere-hour number cooperate the auxiliary starting device of assembling suitable capacity super capacitor to reach must to use big ampere-hour originally just can reach, thereby the user is increased under the little situation at cost, better one push start performance is provided, and owing to effectively raise the starting output current of automobile power system (storage battery+electric capacity), the working life of having improved storage battery greatly.
