Abstract
The utility model provides a battery-replaceable power supply device of an electric vehicle, which comprises a main battery electrically connected with a driving motor of the electric vehicle, and is characterized in that a switching switch is arranged on a connection circuit arranged between the driving motor and the main battery, the switching switch is connected with an auxiliary battery through wires, and a charging switch is connected through wires with a connection circuit arranged between the switching switch and the main battery and a connection circuit arranged between the switching switch and the auxiliary battery. Power can be supplied to the driving motor of the vehicle by the main battery or the auxiliary battery, and the auxiliary battery can be repeated replaced so as to provide power energy for the vehicle for long-distance travel. During short-distance travel, the auxiliary battery is taken off, and power is supplied only by the main battery, so that less space is occupied, and weight of the whole vehicle is reduced. The main battery and the auxiliary battery is charged through the charging switch when the grid reaches a trough, so that not only is the grid not affected at all, but also transportation cost of the vehicle is saved, and service life of the batteries is prolonged.
Description
Technical field
The utility model relates to a kind of supply unit, and especially a kind of used for electric vehicle supply unit belongs to power supply device of electric automobile design and manufacturing technology field.
Background technology
Along with tellurian oil resources reduce gradually, each state is all at the automobile that taps a new source of energy of going into overdrive, and electronlmobil is exactly wherein a kind of.Be installed at present on the electronlmobil rechargeable power supply---there is following point in battery pack: the one because Heavy Weight, the weight of battery pack is about 1/3 of tare, be reasonable counterweight, and safety, stability and the anti-theft of the use of guarantee battery pack, mostly battery pack is installed in the under-seat at vehicle middle part, thereby it is increased the difficulty of quick replacing battery, and extremely inconvenient.Therefore, be necessary prior art is improved.
Summary of the invention
For overcoming the battery altering difficulty that existing electric car power supply exists, use deficiencies such as inconvenience, the utility model provides a kind of electronlmobil to change electric formula supply unit.
The utility model provides a kind of like this electronlmobil and changes electric formula supply unit, comprise the main battery that is electrically connected with driving motor for electric automobile, it is characterized in that on the junction circuit between driving motor for electric automobile and the main battery, change-over swith is set, this change-over swith links to each other with boosting battery by lead, and, be connected with charge switch by lead on the junction circuit between change-over swith and the main battery and on the junction circuit between change-over swith and the boosting battery.So that behind the switch transition switch, power to automobile drive electric motor as required, charge to main battery and boosting battery by charge switch again by main battery or boosting battery.
Described main battery is installed in the below, seat at automobile middle part routinely, to keep the automobile counterweight balance.
Described boosting battery is movably arranged in the automobile boot as required, powers to automobile drive electric motor by main battery or boosting battery so that the back is installed, to satisfy the needed electric energy of long-distance running; After main battery and boosting battery electric weight exhaust, boosting battery is unloaded, change the emergency battery that is full of electricity, continue to provide electric energy to electronlmobil; When short distance is travelled, only by main battery power supply, alleviate complete vehicle weight after boosting battery can being unloaded, abdicate the automobile boot space, to adapt to the short distance needs that travel.
The utility model compared with prior art has following advantage and effect: adopt such scheme, promptly under the situation of conventional main battery power supply, set up the movable auxiliary power supply battery that is provided with, and the power supply of main battery and boosting battery is switched by change-over swith, provide enough electric energy with automobile to long-distance running, and can constantly change boosting battery, guaranteed the continuation of travelling; When running car is short distance, can take off boosting battery, only, do not take the automobile more space, alleviate complete vehicle weight by the main battery power supply, can charge to main battery and boosting battery in the electrical network low ebb time period by charge switch simultaneously, neither can have any impact to electrical network, it is preferential to enjoy the low ebb electricity price again, saves the automotive operation cost, also helping and prolong battery service life, is a desirable electric car power supply device.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
The electric car power supply device that the utility model provides, comprise the main battery 1 that is electrically connected with driving motor for electric automobile, on the junction circuit between automobile drive electric motor and the main battery 1, change-over swith 2 is set, this change-over swith 2 links to each other with boosting battery 6 by lead, and, be connected with charge switch 5 by lead on the junction circuit between change-over swith 2 and the main battery 1 and on the junction circuit between change-over swith 2 and the boosting battery 6; Described main battery 1 is installed in the below, seat at automobile middle part routinely, to keep the automobile counterweight balance; Described boosting battery 6 is movably arranged in the automobile boot as required, so that pass through main battery 1 or boosting battery 6 after installing to automobile drive electric motor feed drive power supply 3, to satisfy the needed electric energy of long-distance running, after main battery 1 and boosting battery 6 electric weight exhaust, boosting battery 6 is unloaded, change the emergency battery that is full of electricity, continue to provide driving power 3, guaranteed the continuation of travelling to automobile drive electric motor; When needing charging, electric network source 4 is charged to main battery 1 and boosting battery 6 simultaneously by charge switch 5, as Fig. 1.
