Description

A kind of cell charge protection plate circuit of timing metering

Technical field

The utility model relates to battery protecting plate technical field more particularly to a kind of cell charge protection plates of timing metering Circuit.

Background technique

Currently, as new-energy automobile, electric vehicle lithium battery are constantly widely applied on the market, especially many electric vehicles User can mention battery to charge in high-rise house.When the electronics failure or burn-up in charger cause to charge it is too strong, Battery-heating deformation, in fact it could happen that battery explosion and life and property loss, it is therefore desirable to a capacity timing and can metering fill Electric protection plate.

Summary of the invention

The purpose of this utility model is to provide a kind of cell charge protection plate circuits of timing metering.

The technical solution adopted in the utility model is:

A kind of cell charge protection plate circuit of timing metering comprising charging head and protection board, charging head have and fill The positive terminal and negative pole end of electric appliance docking, the output end of protection board are connect with battery, and charging head passes sequentially through a charging metering device With the input terminal of timer access protection board, charging metering device includes relay and counter, the positive terminal difference of charging head One end of the control coil of relay and the anode of timer input terminal are connected, the negative pole end of charging head is separately connected relay The other end of control coil and the cathode of timer input terminal, counter have an inductive connector, inductive connector be correspondingly arranged at after One end of the control coil iron core of electric appliance, inductive connector is sucked in relay when relay power, relay pine when relay powers off Inductive connector is opened, once electrification and power-down-counters complete primary count；The output end of timer anode and cathode respectively with The corresponding terminal connection of protection board input terminal, timer disconnect charge circuit when reaching setting time.

Further, the positive terminal of the charging head connects the one of the control coil of relay by a protection diode End, the positive terminal of charging head connect the anode of timer input terminal by another protection diode.

Further, preferably, relay is Miniature counter, and relay and counter can be sealed integrally Dress.

Further, the counter is ac-5j counter.

It further, further include battery capacity detection circuit, battery capacity detection circuit is the detection of existing normal capacity Circuit, battery capacity detection circuit both ends are respectively connected to the corresponding terminal of protection board input terminal, battery capacity detection circuit detection The residual capacity of the preceding battery of charging simultaneously shows remaining battery capacity by a battery capacity display screen.

Further, the timer is timer when can set, what user can be detected based on battery capacity detection circuit Battery remaining power adjusts the charging time, avoids overcharging to control charging duration.

Further, the timer is cn101a timer.

The utility model uses above technical scheme, provides battery capacity detection, is based on surveyed capacity convenient for user and passes through The timer setting charging time prevents from overcharging to battery, while counter is arranged and counts to the charging times of battery totality Number, the battery effectively controlled add up charging times, and control battery using state effectively avoids the generation of risk.

Detailed description of the invention

The utility model is described in further details below in conjunction with the drawings and specific embodiments；

Fig. 1 is a kind of circuit theory schematic diagram of the cell charge protection plate circuit of timing metering of the utility model.

Specific embodiment

As shown in Figure 1, the utility model discloses a kind of cell charge protection plate circuits of timing metering comprising charging Head and protection board, charging head have the positive terminal and negative pole end docked with charger, and the output end of protection board connect with battery, fills Dateline pass sequentially through a charging metering device and a timer access protection board input terminal, charging metering device include relay K1 and Counter T1, the positive terminal of charging head are separately connected one end of the control coil of relay K1 and the anode of timer input terminal, The negative pole end of charging head is separately connected the other end of the control coil of relay K1 and the cathode of timer input terminal, counter T1 With an inductive connector, inductive connector is correspondingly arranged at one end of the control coil iron core of relay K1, when relay K1 is powered after Inductive connector is sucked in electric appliance K1, and relay K1 unclamps inductive connector, once electrification and power-down-counters T1 when relay K1 is powered off Complete primary count；The terminal connection corresponding with protection board input terminal respectively of the anode and cathode of the output end of timer, timing Device disconnects charge circuit when reaching setting time.

Further, the positive terminal of the charging head passes through the control coil of a protection diode D2 connection relay K1 One end, the anode that the positive terminal of charging head passes through another protection diode D1 connection timer input terminal.

Further, preferably, relay K1 is that Miniature counter T1, relay K1 and counter T1 can Integral packaging.

Further, the counter T1 is ac-5j counter T1.

Further, the timer is cn101a timer.

The utility model uses above technical scheme, and setting counter T1 counts the charging times of battery totality, The battery effectively controlled adds up charging times, and control battery using state effectively avoids the generation of risk.In addition, also providing Battery capacity detection, be based on surveyed capacity convenient for user prevents from overcharging to battery by the timer setting charging time.
