Description
Technical field
The utility model relates to a kind of battery check device.
Technical background
The battery electric quantity display device of existing electric bicycle all is to show battery terminal voltage.When battery charge, setting by the charge parameter that is complementary between charger and battery and battery terminal voltage is detected, add then some pilot lamp allow the user judge whether battery has been full of or less than, but the user does not know how many electric weight battery has filled into, can only bear with the charger demonstration and completely just can use, use extremely inconvenient.When battery discharge, display device reflects the electric weight of battery again by the terminal voltage that detects battery, but flash-over characteristic according to battery, in the short time, add heavy load, the terminal voltage of battery can sharply descend, and after removing load, the terminal voltage of battery can rise again, therefore, battery terminal voltage can not entirely true reflection battery electric quantity, allows the operable time that the user can not the exact grasp electric bicycle, often occur exhausting and can't travelling such as electric weight in use, or the abundant but still situations such as the charging of taking away of battery electric quantity, allow the people use the very inconvenience of electronic bicycle, and the serviceable life of damaging battery easily.So, the demonstration battery electric quantity that above-mentioned existing battery check device can not be correct.
The utility model content
The utility model is to provide a kind of pick-up unit that can correctly show battery electric quantity.
The battery electric quantity checking device of a kind of electric bicycle described in the utility model comprises the voltage detecting circuit that detects the anode terminal voltage, it is characterized in that, also comprises:
Current detection circuit extremely links to each other with battery one, and its output terminal connects multiplier;
Clock generator is connected with totalizer with multiplier, for multiplier and totalizer provide clock signal;
Multiplier, the time interval value three that the magnitude of voltage that voltage detecting circuit is measured, the current value that current detection circuit is measured and clock generator produce is multiplied each other, and the output terminal of product connects totalizer;
Totalizer, it is every the product accumulation of a time interval value with multiplier output, and accumulation result sends to display unit by its output terminal;
Current direction detector extremely links to each other with battery one, and its output terminal connects totalizer, is used to control the computing that totalizer adds deduct to current data.
Battery electric quantity checking device described in the utility model, in the process of charging and discharge, measure the instant terminal voltage and the charging and discharging currents of battery, then according to electric energy computing formula W=U*I*T, the time interval value that voltage, the electric current that measures is input to multiplier and clock generator generation multiplies each other, drawn a sub-in short-term electric weight, be input to totalizer then, again each sub-electric weight has been added up, then drawn the total electric weight of battery after charging, shown by display unit at last.Current direction detector then can judge that battery is in charging or discharge by detecting sense of current, then judged result is delivered to totalizer, and totalizer determines that according to this result the detection electric weight of this period is just (charging) still negative (discharge).Therefore, the demonstration battery electric quantity that this battery electric quantity checking device can be correct allows the user can accurately grasp the operable time of electric bicycle, and has protected battery, increases its serviceable life.
