Abstract
The utility model relates to a battery-battery mixed power source used by an electric automobile, which combines two lithium ion power batteries with different performances and a current limiting element into a whole and can be used for a power system of a clean energy automobile. A lithium ion battery pack can meet the requirements of rapid discharge of large current and speed enhancement of an automobile when a mixed power automobile starts and accelerates, and braking energy can be quickly recovered and fed back during braking and declivity and is stored in the lithium ion battery pack.
Description
Technical field
The utility model belongs to the clean energy resource automobile technical field, belongs to a kind of new-energy automobile propulsion source, particularly a kind of used for electric vehicle hybrid power system.
Background technology
At present, energy-saving and emission-reduction are major issues of the international people's livelihood of relation, people are at the novel alternative energy of attempting to use beyond the oil, thereby auto trade various new-energy automobiles just occurred as substitute fuel automobile or electronlmobil.Electronlmobil is because characteristics such as its environmental protection, energy-conservation, efficient height receive increasingly extensive concern.And one of critical component of battery-driven car is exactly an electrokinetic cell.
The advantage of pure electric automobile is the zero-emission of travelling, but travelled distance falls short of, thus only use on fixed lines such as public transport, postal service, road-cleaning now, and require high to Infrastructure such as charging websites, disposable having high input, developing and promoting the use of also needs a process.
Though hybrid vehicle is not zero-emission, can be by adding the battery pack of a constant volume, the lithium ion battery group will satisfy the hybrid vehicle startup, big electric current discharges rapidly when quickening, promote the requirement of car speed, when drag, descending, also can reclaim the regenerative braking energy fast, be stored in the lithium ion battery group.Can reduce engine power like this, make it to be operated in efficient district simultaneously, reach purpose energy-conservation and that reduce discharging.
Summary of the invention
The purpose of this utility model is just in order to overcome above-mentioned prior art weak point, and provide a kind of electric powered motor source, this propulsion source comprises: a high power type lithium ion power battery pack and a high-energy type lithium-ion-power cell group, and the adding current limiting element, such propulsion source has had both the performance of high power type lithium ion power battery pack and high-energy type lithium-ion-power cell group.
The purpose of this utility model realizes by following technical proposal:
Propulsion source, it mainly is made of high-energy type lithium-ion-power cell group (1), high power type lithium ion power battery pack (2), current limiting element (3), IGBT switching valve (4).Can stablize permanent power and good acceleration capability for battery-driven car provides, and can reclaim braking energy, Zero-discharge non-pollution fast.
It is characterized in that: the high power type lithium ion power battery pack in the described propulsion source is can meet battery-driven car to starting the high-specific-power battery of power requirement, and it allows transient large current discharge and charging, and does not influence its other performances.
Described high-energy type lithium-ion-power cell group has high-energy-density, and the electric energy of lasting stability can be provided for battery-driven car.
Described current limiting element is one can suppress the coil that big electric current passes through, and high energy battery is carried out electric current suppress protective effect.
The beneficial effects of the utility model are, have solved the pure electric vehicle acceleration capability and have reclaimed the problem of braking energy fast, realize real " zero pollute, zero-emission ".
Description of drawings
Further specify below in conjunction with accompanying drawing with to the utility model.
Fig. 1 is the propulsion source structural representation
Fig. 2 is energy output and recovery scheme drawing
The specific embodiment
In Fig. 1, (1) is the battery pack that many high-energy type lithium-ion-power cell connection in series-parallel are formed, and (2) are the battery pack that many high power type lithium ion electrokinetic cells are formed.Be be pre-assembled, lithium-ion-power cell group that conformability is good.High-energy type lithium-ion-power cell group (1) is in parallel with high power type lithium ion power battery pack (2), and at middle current limiting element (3), the switching valve (4) of connecting again of adding in parallel.
When automobile starting, use the energy that provides by (2) to make the motor start-up vehicle starting, does not at this moment work (1).Enter at the beginning of vehicle start in the low speed driving process, (2) are in the fuller state of electric weight, and its energy output can be satisfied the requirement of vehicle launch, and (1) does not need work; When automobile progressively enters steadily and the process of giving it the gun, at this moment when (2) total voltage be lower than primary voltage 80% the time, battery management system (BMS) detects this signal, make the IGBT conducting, make and be (1) output electric energy (2) charging, and work as vehicle and quicken, when big, provide energy for electrical motor for energy requirement simultaneously; Work as car retardation, less for energy requirement, and when having dump energy to reclaim, motor is with dump energy input (2), and (2) are because its high-specific-power performance can the fast Absorption braking energy, can also pass through (3) when it has dump energy simultaneously, big electric current be controlled the back carry out the electric energy feedback for (1).
Claims (2)
1. battery for electric automobile-cell hybrid power source, it mainly is made of the battery pack and the current limiting element of two groups of different performance characteristics, it is characterized in that: the battery pack of described two groups of different performance characteristics wherein one group be the high power type lithium ion power battery pack, another group is for high-energy type lithium-ion-power cell group.
2. battery according to claim 1-cell hybrid power source, the wherein battery pack parallel connection of two groups of different performance characteristics, and at the middle current limiting element that adds in parallel.
