Description
Technical field
The utility model relates to the energy supply battery of EMB braking motor in a kind of automobile EMB braking system.
Background technology
The EMB braking system is the brake system of car future thrust, and this system is different from existing air-pressure brake and brake fluid system.The EMB braking system is to adopt electric braking fully, and when vehicle was implemented service brake, the motor on the EMB braking clamp body was accepted instruction, and implementation promotes friction plate and brake disc friction, thereby finishes braking.Mainly there are moving, several forms such as braking and slow application soon of braking, recasting in car brakeing, the EMB braking motor needs to implement action according to above-mentioned different situations, and consume different energy, this energy is provided by on-vehicle battery, general super capacitor or the lithium battery of adopting singlely, but it has following pluses and minuses separately:
Super capacitor: super capacitor is a kind of energy-storage travelling wave tube between battery and electrostatic condenser, has very high power density, is suitable as short time power output source.Have big, the advantages such as an energy storage is many, long working life of specific power height, specific energy; Its shortcoming is for can only discharge and recharge the short time.
Lithium battery: with respect to super capacitor, its major advantage is energy storage for a long time, discharges and recharges rapidly; Its shortcoming is mainly and costs an arm and a leg, and the electric current of increasing income is little, and useful life is relatively low.
The utility model content
The purpose of this utility model is to provide a kind of automobile EMB use for brake system composite battery group, can effectively solve existing this composite battery group for car brakeing provides required electric energy, is different from the electrokinetic cell on electric motor car, the hybrid vehicle, does not do power supply.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of automobile EMB use for brake system composite battery group, it is characterized in that: comprise energy supply control module, super capacitor and energy-storage battery, energy supply control module all connects and controls super capacitor and energy-storage battery discharges and recharges, super capacitor connects and driving EMB braking motor, energy-storage battery connects the EMB braking motor, and at the super capacitor electric weight not enough or process auxiliary drive EMB braking motor when losing efficacy, energy-storage battery connects super capacitor and super capacitor is charged.
Preferably, energy-storage battery adopts lithium battery.
Preferably, energy-storage battery adopts lead-acid battery, Ni-MH battery, fuel cell.
The utility model is owing to adopted technique scheme, the combining super capacitor characteristics, bring into play its fast charging and discharging, and characteristic such as specific energy, specific power be big, preferred supply unit as the EMB braking motor, thereby effectively protect energy-storage battery, wherein energy-storage battery is preferably lithium battery, prolongs its useful life, super capacitor low price, long working life can effectively reduce use cost; This composite battery group can be the EMB braking motor according to different needs such as a braking, moving, the fast braking of recasting, slow application and energy supply, when energy-storage battery or super capacitor inefficacy, both all can independently implement braking, guarantee vehicle driving safety, improve braking reliability and vehicle safety coefficient.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the block diagram of a kind of automobile EMB of the utility model use for brake system composite battery group.
Embodiment
As shown in Figure 1, be a kind of automobile EMB of the utility model use for brake system composite battery group, comprise energy supply control module, super capacitor and energy-storage battery, energy supply control module all connects and controls super capacitor and energy-storage battery discharges and recharges, super capacitor connects and driving EMB braking motor 1, energy-storage battery connects EMB braking motor 1, and at the super capacitor electric weight not enough or process auxiliary drive EMB braking motor 1 when losing efficacy, energy-storage battery connects super capacitor and super capacitor is charged, energy-storage battery is charged by mobile generator, energy-storage battery preferably adopts lithium battery, can certainly adopt lead-acid battery, Ni-MH battery, fuel cell.Connect as Fig. 1, EMB braking motor 1 provides actuating force for the EMB brake; Super capacitor is a short time power output source, is preferably 1 power supply of EMB braking motor, the protection energy-storage battery; Energy-storage battery is the super capacitor charging, is the braking motor energy supply in emergency circumstances, also can accept the generator electric energy simultaneously and charge once more.
When 1) vehicle was implemented braking, promptly the composite battery group was implemented discharge, and its discharge process is as follows:
When vehicle is implemented some braking and slow application, EMB braking motor 1 less energy intensive, the super capacitor energy stored is enough to provide motor to implement the some braking, and super capacitor is the required electric weight of supply under energy supply control module control, and this moment, energy-storage battery was not worked.
When vehicle implemented to remake moving and fast braking, EMB braking motor 1 consumed energy big, and demand is urgent, and its short time power output source characteristics are brought into play in the rapid discharge in full under energy supply control module control of super capacitor this moment; When super capacitor internal memory electric weight is not enough,, guaranteed the required energy consumption of braking motor by energy-storage battery cooperation power supply.
2) during the vehicle brake off, promptly the composite battery group need be implemented charging, and its charging process is as follows:
Because of vehicle may be implemented braking at any time,, super capacitor keep electric weight fully loaded so taking to carve.After the enforcement braking was finished, the super capacitor self-energy consumed, and is that super capacitor replenishes by energy-storage battery; It is that energy-storage battery charges that mobile generator is arranged in the vehicle ' process.Both all can independently implement braking, and when energy-storage battery or the single inefficacy of super capacitor, another still can independently implement braking, guarantees vehicle driving safety.
