Display unit: show charging delay duration and charged state.
Relay; After time-delay finished, charger was started working, and after charger is finished charging, turn-offed power supply, realized that unattended operation cuts off.
Switching Converter Topologies: press pwm signal, control charger output state.
Sampling unit: output current and voltage to charger are sampled, and sampled data is sent into central processing unit;
Central processing unit: receive the delay time setting of input unit input, the line delay of going forward side by side control, time-delay finishes starting relay; Produce pwm signal, the operating state of control switch converter circuit; Read output current and magnitude of voltage that sampling unit is sent into, charged state is judged, setting the floating charge time is 1-5 hour (according to the battery types setting), and the floating charge stage is sent signal to relay after finishing, and cuts off power supply.
The annexation of above-mentioned parts is as follows.
The connection of central processing unit control relay with close; Central processing unit sends the operating state of Signal-controlled switch converter circuit; Input unit is to central processing unit input charging delay time; Delay time and charged state that display unit reads in the central processing unit show; Sampling unit is gathered electric current and the voltage data in the output circuit, and data are sent into central processing unit.
Be provided with in the described central processing unit: the PWM module, described PWM module produces the operating state of pwm control signal control switch converter circuit.
Be provided with in the described central processing unit: the contrast unit, behind electric current in the sampling unit collection output circuit and the voltage data input central processing unit, through the contrast of contrast unit, judgement charger state of living in; If charger is in charged state, central processing unit control PWM module operate as normal, in case the charger charging finishes, central processing unit sends signal to relay, and relay turn-offs power supply, and charger quits work.
Be provided with in the described central processing unit: timing unit, delay time and floating charge time are carried out timing control, the delay time timing finishes, and starts or the shutoff relay.
Beneficial effect: intelligent charger of the present invention compared with prior art has following advantage:
Intelligent charger of the present invention can be set the charge initiation time according to customer requirements, and after being full of, battery electric quantity can cut off the electricity supply automatically, prolong battery useful life, saved the energy, reduced the user power utilization expense, can also respond country and call, utilance when improving electrical network paddy reduces carbon emission.
Description of drawings
Fig. 1 is the construction module schematic diagram of intelligent charger of the present invention.
Embodiment
Below in conjunction with specific embodiment, further illustrate the present invention, should understand these embodiment only is used to the present invention is described and is not used in and limit the scope of the invention, after having read the present invention, those skilled in the art all fall within the application's claims to the modification of the various equivalent form of values of the present invention and limit.
Embodiment
A kind of intelligent charger, it comprises: input unit, display unit, relay, Switching Converter Topologies, sampling unit and central processing unit.
Be provided with timing unit, contrast unit, PWM control module in the central processing unit; Contrast is set current critical value, floating charge flow valuve and charge threshold level (critical value of electric current is meant that the upper limit of charging current, floating current are meant the current value when battery electric quantity is full of substantially, and the critical value of voltage is meant the upper limit of charging voltage) in the unit.
