Technical field
The utility model relates to a kind of accumulator detection system, especially a kind of valve-control sealed lead acid battery detection system.
Background technology
The cycle life of accumulator and the depth of discharge of accumulator have close relationship, and when valve-regulated sealed lead-acid batteries was 20% at depth of discharge (DOD), cycle life was greater than 1500 times; When depth of discharge is 50%, then cycle life will drop to about 500 times, and when depth of discharge is 80%, cycle life will only have about 200 times.
At present, the function of the aspects such as the charging control model of monitor and detection, measuring accuracy, battery can't meet the actual operation requirements of accumulator fully, if depend on the monitor data result as the sole criterion of judging the accumulator actual operating state, just be not easy to find the potential problem of the current existence in service of accumulator, therefore, be necessary to work out a kind of can being convenient to valve-control sealed lead acid battery is carried out routine testing, in time understand the detection system of its various parameters.
The utility model content
The purpose of this utility model is that a kind of valve-control sealed lead acid battery detection system will be provided, and can detect online and show, learns the current capacity of accumulator by each physical parameter in the measurement valve-control sealed lead acid battery charge and discharge process.
For achieving the above object, technical solutions of the utility model realize:
A kind of valve-control sealed lead acid battery detection system, comprise power supply, microprocessor, described power supply by the city be electrically connected DC adapter, power supply processing module forms, power supply processing module one end ground connection, one end output voltage is received microprocessor, described microprocessor is link voltage A/D converter, temperature sensing A/D converter, electrification reset, keyboard, LCDs respectively, and described terminal voltage A/D converter connects potential-divider network, and potential-divider network connects tested accumulator.
Further, described power supply processing module output voltage is 5V.
Further, described keyboard is the 4*4 stand-alone keypad.
Further, described LCDs specification is 128*64.
The beneficial effects of the utility model are: set up the mathematical model of lead-acid accumulator residual capacity (SOC) with the physical-chemical parameters Relations Amongs such as accumulator voltage, charging and discharging currents, initial electric liquor ratio weight, environment temperatures, based on this mathematical model, just can learn by each physical parameter in the measurement accumulator charging/discharging process the current capacity of accumulator.The utility model is practical in addition, can detect online and show the current capacity of accumulator, and measuring error is less than 10%.
