Embodiment
Below in conjunction with accompanying drawing, function of the present utility model is described.
Described solar panel input way is 1-6 road, is used for as the charging of lead acid accumulator monomer.Solar panel is connected charging-discharging controller through diode D1 with switching element T 1, and charging-discharging controller connects batteries, connects load after batteries parallel diode D2 through switching element T 2.The diode D1 that solar panel connects; due to the unilateral conduction of diode; D1 can prevent overcast and rainy or cause batteries to carry out reverse charge to solar panel because sunlight is inadequate night, and D2 prevents accumulator polarity from connecing instead, plays the effect of circuit protection.
Described charging-discharging controller, its have prevent batteries overcharge and overdischarge effect.
Specific embodiments of the present utility model is illustrated below in conjunction with accompanying drawing 1, as shown in Figure 1: in charging process of storage battery set, loop breaker in middle device T1 closes, when battery charging voltage is greater than " overvoltage reference voltage ", T1 disconnects, no longer batteries is charged, thus ensure that batteries there will not be overcharge, play additives for overcharge protection effect; In charge circuit, diode D1 prevents the batteries when night or rainy weather from, to solar panel reverse charging, playing anti-reverse charge protection effect.
Switching element T 2 is batteries discharge switch, and in batteries discharge process, when the discharge voltage of storage battery is less than " under-voltage reference voltage ", T2 disconnects, and carries out over.
The effect of D2 diode is when batteries reverse polarity connection, and D2 conducting makes batteries by D2 short circuit dischange, produces very big current and is blown by fuse FUSE fast.
Charging-discharging controller detects accumulator battery voltage at any time, when accumulator battery voltage is greater than " overvoltage reference voltage ", T1 is disconnected, carries out additives for overcharge protection to batteries; Make when accumulator battery voltage is less than " under-voltage reference voltage " T2 turn off and carry out over.
Charge-discharge controller circuit figure and operation principle is illustrated below in conjunction with Fig. 2.
Charge-discharge controller circuit comprises overvoltage detection control and under-voltage detection control two parts.
Detection control circuit is made up of operational amplifier.A1 is overvoltage detection control circuit, the reference voltage that the in-phase input end of A1 provides corresponding overvoltage to cut off by K1, and the tested batteries of anti-phase input termination, when battery tension is greater than " overvoltage reference voltage ", A1 output G1 is low level, shutdown switch device T1, cuts off charge circuit, plays overvoltage protection effect; When batteries is by load discharge, accumulator battery voltage starts again to decline, and when the reverse inter-input-ing voltage of A1 is less than homophase input voltage, then its output G1 is by low transition to high level, and switching element T 1 becomes conducting by disconnection, recloses charge circuit." overvoltage reference voltage " coordinates adjustment by K1 and R1.
A2 is under-voltage detection control circuit; " under-voltage reference voltage " that its anti-phase termination is provided by K2; homophase termination battery tension (contrary with overvoltage detection control circuit); when battery tension is less than " under-voltage reference voltage "; A2 output G2 is low level; switching element T 2 disconnects, the output loop of cutting-off controlling device, realizes " under-voltage protection ".After T2 disconnects, along with the rising of accumulator battery voltage, when voltage is again higher than " under-voltage reference voltage ", switching element T 2 conducting again, recovers load supplying." under-voltage reference voltage " coordinates adjustment to obtain by K2 and R2.
Described switching element T 1, T2 utilize mechanical relay to control charge and discharge process.It is generally used for higher-wattage system, and the capacity of relay determines the power grade of charging-discharging controller.The G point of the output point G1 in charge-discharge controller circuit schematic diagram or G2 connecting valve device circuitry schematic diagram, resistance R4, R5 have dividing potential drop effect, and when G point high level, triode Q1 conducting, relay J 1 obtains electric, gets an electric shock closed.Storage battery carries out discharge and recharge; When G point is low level, triode Q1 ends, and relay J 1 no current passes through, and switching device disconnects, and storage battery stops charge and discharge process.
