Abstract
The utility model relates to a standby battery device for electric vehicles, which is structurally characterized in that a power battery is connected with a motor, a standby battery is connected with the power battery in parallel, a double-throw switch is arranged between the standby battery and the power battery, or two ends of the power battery are connected to a detection circuit, an output of the detection circuit is connected with a relay, and a normally closed contact of the relay is arranged on a circuit of the power battery while a normally open contact of the relay is arranged on a circuit of the standby battery. The standby battery device can serve as a power battery to supply power for the motor within a short time when the original power battery is incapable of driving the motor, though the power supplied by the standby battery remains for a short time, the problem of failure of powering the vehicle vehicles at places without power charging stations can be solved. In addition, compared with the power battery, the standby battery device has the advantages of small volume, light weight, lower cost and capability of being ready for use at any time.
Description
Technical field
The utility model relates to battery, particularly a kind of used for electric vehicle emergency battery device.
Background technology
Before the present utility model, all common batteries of gasoline automobile are to be used for air conditioning for automobiles, fan, illumination and other electrical equipment etc., and electronlmobil has just been Duoed an electrokinetic cell than gasoline automobile, and electrokinetic cell is exactly mainly to provide power supply to motor.The electrokinetic cell of electronlmobil in a single day can not drive motor, then electronlmobil just can not have been walked, but because battery technology is limit now, the electrokinetic cell volume is big, cost is high, Heavy Weight, an electrokinetic cell may be equipped with on the electronlmobil, just have only charging,, then just cast anchor if it is far to leave battery-charging station, can only ask trailer company to come trailer, delay very much thing.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned defective, develops a kind of used for electric vehicle emergency battery device.
The technical solution of the utility model is:
Used for electric vehicle emergency battery device, electrokinetic cell connects motor, it is characterized in that emergency battery also connects motor, and emergency battery and electrokinetic cell are connected in parallel, and between the two double-throw switch are set.
The utility model further technical scheme is:
The electrokinetic cell two ends are connected to testing circuit, and electrical equipment is succeeded in testing circuit output, and the relay normally closed interlock is on the electrokinetic cell circuit, and relay normally open contact is on the emergency battery circuit.
Advantage of the present utility model and effect are in time to serve as electrokinetic cell and give motor with power when electrokinetic cell is not enough to drive motor, though the time is very short, before being enough to solve not behind the village not the situation in shop.Specific volume is little, in light weight mutually, cost is also extremely low and the utility model is with electrokinetic cell, in case of need.
Other advantage of the present utility model and effect will go on to say below.
Description of drawings
Fig. 1---the utility model structural principle scheme drawing.
Fig. 2---the utility model structural development scheme drawing.
The specific embodiment
Embodiment 1:
As shown in Figure 1:
Electrokinetic cell 1 circuit connects motor 2, and motor 2 connects emergency battery 3 circuits again, but double-throw switch 4 connects electrokinetic cell 1 and emergency battery 3.
During application:
When electrokinetic cell 1 provided power for motor 2, voltage was 400 volts usually, and electronlmobil just can drive; In case electrokinetic cell 1 voltage is low, when being not enough to drive motor 2, when usually electrokinetic cell 1 voltage was lower than 310 volts, then electrokinetic cell 1 just can't drive motor 2; At this moment, double-throw switch 4 can be left behind, then electrokinetic cell 1 is cut off with the circuit of motor 2, and the circuit of while emergency battery 3 and motor 2 is switched on, electronlmobil can drive again, though can not open farly, opens back or goes to charge still enough to battery-charging station.
But, for fear of manual double-throw switch 4 just when electrokinetic cell 1 can also drive motor 2, making to be less than when using emergency battery 3 and just use in advance, the utility model improves.
Embodiment 2:
As shown in Figure 2:
When electrokinetic cell 1 two ends connect motor 2, also be introduced in test circuit 5, shaping circuit 6 is received in test circuit 5 outputs, shaping circuit 6 outputs are connected to relay 7 coils, the normally closed interlock JB of relay 7 is arranged in electrokinetic cell 1, motor 2 circuits, and the normally open contact JK of relay 7 is arranged in emergency battery 3, motor 2 circuits.
During application:
When test circuit 5 is tested electrokinetic cell 1 both end voltage when being lower than 310 volts, the output high level, and be delivered to shaping circuit 6 and carry out shaping, high level is added on relay 7 coils then, make relay 7 work, normally closed interlock JB is disconnected, electrokinetic cell 1 is cut off with motor 2 circuits, and relay 7 normally open contact JK are closed simultaneously, and the emergency battery 3 and the circuit of motor 2 are switched on, thereby make motor 2 continue and can drive, then electronlmobil just can move ahead again.Like this, avoided people's interference, accomplished that really precautions averts perils.But, because emergency battery 2 finite capacities, can only satisfy usually electronlmobil opened to battery-charging station or home, James and go charging.
Among Fig. 2, test circuit 5, shaping circuit 6 and relay 7 have replaced the double-throw switch 4 among Fig. 1.
