Accompanying drawing explanation
Fig. 1 shows the electric car charger circuit diagram of a kind of embodiment of the present utility model.
Embodiment
Below by specific embodiment, also by reference to the accompanying drawings the utility model is described in further detail.
The electric car charger that the utility model embodiment provides, as shown in Figure 1, comprising: timer 101, bridge rectifier 102, output interface 103 and electric capacity 104;
Wherein, electric capacity 104 is electrically connected between an ac input end (AC) of bridge rectifier 102 and an output of timer 101;
Another ac input end (AC) of bridge rectifier 102 is connected with another output of timer 101;
Between the cathode output end (+) of bridge rectifier 102 and cathode output end (-), be connected output interface 103.
Above-mentioned electric car charger makes charger in overtension or short circuit by the electric capacity of a plurality of parallel connections, regulation voltage voluntarily, and capacitor circuit can not burn, thereby has reduced the potential safety hazard of electric car charger.
Preferably, electric capacity 104 is one.
Preferably, electric capacity 104 is a plurality of, and a plurality of Capacitance parallel connections are between ac input end and an output of timer of bridge rectifier.
Preferably, electric capacity 104 is 2-8.
Electric capacity quantity can be selected according to capacitance, and when capacitance is larger, electric capacity quantity can be less, when capacity hour, electric capacity quantity is more.
Output interface 103 and electric capacity 104 are one group of charging port, and electric car charger can comprise many group charging ports, thereby can be a plurality of electric motor car chargings simultaneously.
Wherein, the timing of timer 101 is any, and preferably, timer 101 can comprise 30 minutes, 60 minutes, 120 minutes 3 timings, makes user that the charging interval of charger can be set as required flexibly.
When being input as 220V, coordinate electric capacity 104(can comprise 1～8 or a plurality of electric capacity 104), can export the needed charging voltage of various electric vehicle accumulators, the direct current that output current is 150mA-300mA, can adapt to the demand of most of electric motor cars.
When having charging terminal charging, charging terminal will become an electric capacity, can comprise 1～8 or a plurality of electric capacity 104 with electric capacity 104() in parallel, electric capacity 104(can comprise 1～8 or a plurality of electric capacity 104) can automatically be adjusted to the needed voltage of electric motor car, can automatically be adjusted to according to electric motor car charging voltage the Voltage-output of 12-144V, electric current remains 150MA～300MA, thereby can be the electric motor car charging of different voltage requirements, when voltage surpasses 144V, have the problem of fail safe.When without any electric motor car, when charger itself forms loop (short-circuit condition), electric capacity 104 can regulate automatically, and charger can not burnt.
This charger is to the not restriction of the quantity of electric motor car, for not restriction of voltage, when quantity surpasses some, when voltage has surpassed 144V, can increase quantity and the voltage that can hold electric motor car by increasing quantity or the capacity of electric capacity in parallel 104.It is unit that electric capacity increase can be take 1～8 electric capacity in parallel, and the electric capacity that also can expand to a plurality of parallel connections is unit.
