Abstract
The invention discloses electrical equipment matched with a battery pack. By means of designing a rated operational voltage range of the electrical equipment into integral multiples of that of a simple battery of the matched battery pack, DC-DC (direct current-direct current) converters in a battery pack system are omitted. The electrical equipment matched with the battery pack has the advantages that electric energy loss of the DC-DC converters during operation is avoided, endurance of the battery pack can be enhanced, the size and the weight of the battery pack system can be decreased and cost is reduced.
Description
Technical field
The present invention relates to low voltage electrical equipment, especially relate to the low voltage electrical equipment supporting with battery pack.
Background technology
In the system taking battery pack as power supply, especially with output voltage higher than in the mesohigh battery pack of the 36V system that is power supply, generally there is high voltage electric equipment and low voltage equipment simultaneously; Supplying power for outside output conversion apparatus as energy-storage system is high-tension apparatus, and the controller etc. of energy-storage system belongs to low-voltage equipment; Motor as electric automobile is high-tension apparatus, and instrument/headlight/direction indicator lamp/loudspeaker/VCU/ power windows/skylight/rain brush/power assistance pump for steering/ABS/ air bag etc. belong to low-voltage equipment; Therefore battery pack system is all equipped with dc-dc the High voltage output of battery pack is changed into low pressure to make these low voltage electrical equipment work.For another example Vehicular solar battery, the generating equipment such as damping capacity recovery system and brake energy recovering system of electric motor car, need the output of generating equipment to change into high pressure by dc-dc, carry out serial connection charge to battery pack.
Application publication number is that the Chinese patent literature of CN105186630A discloses a kind of electric energy bussing technique, can realize utilizing a certain piece of battery that dump energy is the highest in battery pack to be powered to electrical load by electric energy bus, if the operating voltage of electrical load is not mated with the output voltage of this cell, then need to access a dc-dc in electrical load front end, normally work to make this electrical load.
Because dc-dc operationally all exists operating efficiency problem, the use of dc-dc is equivalent to the electric energy wasting valuable battery pack, reduces the flying power of battery pack; Dc-dc also occupies the volume and weight of system simultaneously, and adds the cost of system.
Summary of the invention
The technical scheme of the electric equipment supporting with battery pack disclosed by the invention, by the rated operational voltage scope of described electric equipment is designed to the N of cell rated operational voltage scope of supporting battery pack doubly (N is integer, N=1,2,3 ...) mode, reach the object of the dc-dc saved in battery pack system.
Further, the output voltage of described battery pack is not less than 36V.
Further, described electric equipment does not contain rated operational voltage is the electric equipment of 12V and 24V.
Further, the rated operational voltage of described electric equipment lower than battery pack output voltage and not higher than 36V, namely within the scope of human safety voltage.
Further, described electric equipment comprise can with the various generating equipment of battery pack auxiliary work and electrical load.
Further, generating equipment comprises the equipment that power conversion other forms of except electric energy can be become electric energy, as solar power plant, wind energy generating plant, hydro-electric power generating equipment, generating equipment of internal-combustion engine, thermal generating equipment, mechanical energy generating equipment etc.
Further, electrical load comprises the part, parts, equipment or the electronic devices and components that need external power source just can normally work, controller as various in VCU, BMS etc., instrument/headlight/direction indicator lamp/loudspeaker/power windows/skylight/rain brush/power assistance pump for steering/oil pump/fan/ABS/ air bag/sound equipment/camera/wait various part, parts and equipment, relay, contactor and various sensor electronic component.
Further, the rated operational voltage of generating equipment refers to the output voltage of generating equipment, and the rated operational voltage of electrical load refers to the input voltage of electrical load.
Further, described battery pack need be equipped with electricity transfer bus or electric energy bus or the system such as power distribution bus or some battery pack balancing subsystem, and namely whole battery pack system has the function that the battery be connected in series continuously of more than 1 or 1 in battery pack or cell parallel module can be connected with electric equipment separately.
The invention discloses the electric equipment supporting with battery pack, beneficial effect is the dc-dc can saved in battery pack system, avoid electric energy loss during dc-dc work on the one hand, the flying power of battery pack can be increased, the volume and weight of battery pack system can be reduced and reduce costs on the other hand.
Fig. 1 is the electric equipment application schematic block diagram supporting with battery pack.
Embodiment
Below with reference to the accompanying drawings and specific embodiment the invention will be further described.Should be understood that these drawings and Examples only for the purpose of illustrating the invention, and be not used for limiting the scope of the invention.Those skilled in the art can according to principle of the present invention and by suitable conversion and substitute realize more function or expand range of application of the present invention.
With reference to figure 1, describe the application schematic block diagram of electric equipment of the present invention, the supporting electric equipment of battery pack 101 comprises generating equipment 102 and electrical load 103, and wherein the rated operational voltage of electrical load 103 is designed to identical with the rated output voltage of cell (i.e. the relation of 1 times).Battery pack 101 is composed in series by 96 battery modules, wherein each battery module is composed in parallel by some cells, therefore the rated output voltage of each battery module is identical with the rated output voltage of cell, 96 battery modules, generating equipment 102, electrical loads 103 are connected with electric energy bus 104 by switch, and the break-make of all switches is all by the control of electric energy bus control unit 105.Suppose the dump energy of now 1# battery module 106 the highest and now electrical load 103 need work, electric energy bus control unit 105 control switch 107 and switch 108 are connected, now 1# battery module 106 passes through switch 107, electric energy bus 104, switch 108, is finally connected with electrical load 103, because the rated operational voltage of electrical load 103 is identical with the rated voltage of cell, now 1# battery module 106 is powered directly to electrical load 103, without the need to getting final product work through any dc-dc, save dc-dc.
The corollary equipment that electric equipment disclosed by the invention can be used as battery pack is applied in any environment having battery pack, includes but not limited to following industry or product: the fields such as the backup battery group of the battery energy storage system of electric bicycle, electric automobile, electronic engineering truck, naval vessel submarine, train, the backup power system of machine room, communication power supply, the battery pack of field movable communication base station, the various battery energy storage systems comprising photovoltaic generation and wind power generation, the battery pack system of aerospace vehicle, the battery pack system of naval vessel submarine.
