Further illustrate as the present invention, described charging output is provided with the adjustable resistance that can change the charging current of charging output, charging current, according to the output of the detection Data Control charging output of detection module, controls in certain scope, ensures safety utilization of electric power by described control module.
Further, the civilian power safety charging device of described electric motor car is also provided with the setup unit of the upper loading limit for inputting Domestic distribution circuit.
Further, the civilian power safety charging device of described electric motor car is also provided with the display screen showing to come the data such as wiring load power and charging current in real time.
Further, described detection module comprises current sensor and power transformation resistance.
Advantage of the present invention:
The civilian power safety charging device of electric motor car of the present invention is provided with detection module for detecting the load of electric wire, according to the load capacity of Domestic distribution circuit, automatic adjustment charging output current, charging current is made to remain in certain scope, ensure safety utilization of electric power, avoid the overload causing Domestic distribution circuit to generate heat, decrease the use electrification because electric motor car charging causes; Exist in charging process, the civilian power safety charging device monitoring of electric motor car carrys out the load variations of electric wire, and the load carrying out electric wire increases, then reduce charging current, the load carrying out electric wire reduces, then then can add charging current, namely under the prerequisite ensureing safe charging, ensures charge efficiency; Running parameter can set, and set different running parameters according to different Domestic distribution line load abilities, applicability is wide; Be provided with display screen display monitoring data directly perceived.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Reference numeral: power input 1, detection module 2, control module 3, charging output 4.
Embodiment
Embodiment:
The civilian power safety charging device of a kind of electric motor car, comprises power input 1, detection module 2, control module 3 and charging output 4, power input 1 connects Domestic distribution circuit, for providing charge power supply, detection module 2 is serially connected with between power input 1 and control module 3, can detect the electric current of electric wire, for monitoring the load variations of electric wire, control module 3 input is connected with detection module 2, output is connected with charging output 4, charging output 4 is provided with an adjustable resistance, the charging current of charging output 4 can be changed, control module 3 is according to the output of the detection Data Control charging output 4 of detection module 2, charging current is controlled in certain scope, ensure safety utilization of electric power.Preferably, device can arrange a display screen, and display in real time carrys out the data such as wiring load power and charging current, can arrange a setup unit further, for inputting the upper loading limit of Domestic distribution circuit.
The present embodiment course of work is: the civilian power safety charging device of electric motor car sets a upper loading limit value, when electric motor car access Domestic distribution line charging, detection module 2 meeting Real-Time Monitoring carrys out the electric current of electric wire, control module 3 automatically calculates the load of electric wire, and charges to electric motor car with the above-mentioned upper loading limit value charging current that output 4 exports a safety that controls more afterwards to charge; The load variations of electric wire monitored by the civilian power safety charging device of electric motor car in charging process, changes charging current in real time.Such as, the upper loading limit of a Domestic distribution circuit is 10 kilowatts, during electric motor car civilian power safety charging device access charging, the actual loading that control module 3 calculates electric wire by the detection data of detection module is 9 kilowatts, then control module 3 controls the charging current of charging output 4, makes the power of the civilian power safety charging device of electric motor car be less than 1 kilowatt; Exist in charging process, the civilian power safety charging device monitoring of electric motor car carrys out the load variations of electric wire, and the load carrying out electric wire increases, then reduce charging current, the load carrying out electric wire reduces, then then can add charging current, namely under the prerequisite ensureing safe charging, ensures charge efficiency.
