20A battery capacity tester 
Introduction
In recent years , the electric car industry has been rapid development , as the traction battery , its performance has a direct impact on the electric vehicle usage. Tubular battery production technology matured, the quality continues to improve, but because the charger on the market circulation of varying quality, coupled with a poor knowledge of the user charge , resulting in a lot of otherwise good quality battery time is not long ( six months warranty period ) will not charge the power , electric cars do not run way , users clamor retirement vehicles , battery back , bring a lot of trouble and loss to manufacturers and dealers. Unfortunately there were no testing equipment and testing instruments, can be returned unconditionally , " bear the major economic loss should not bear ." " Xi Yuan for batteries for businesses to problem-solving " became the lead company bounden duty. Our newly developed XDDC-10A battery capacity tester to fill this gap in the market . It uses a constant current discharge of a battery can be simultaneously (4 to 5 ) is detected in a short discharge (4 to 5 hours ) , to accurately detect the battery capacity , while also the quality of each of a battery performance a testing battery performance for judging the merits of providing a reliable basis . With the use of pilot production company, " intelligent automatic constant current charging machine" , "three charge two release" for maintenance, can damage the battery capacity is basically restored to more than 80 % of rated capacity , that satisfied customers, but also to restore the economic losses. Thus, the product available , then the majority of users of all ages , they become indispensable good helper.
Product Features:
1 , the parameters of the digital control loop display
2 , fault tips display
3 , data collection , storage and output functions
4 , data query functions
5 , reverse polarity protection
6 , computer programming control , safe, reliable , easy to operate
Technical parameters:
1 , Suitable for : 48V battery pack (4 × 12V), 60V battery pack (5 × 12V)
( Single battery capacity is 80 ~ 300AH)
2 , the discharge current: 10A constant
3 , the discharge termination voltage : 40V (4 × 10V), 50V (5 × 10V)
Function and digital display shows
Display format and content
1, the current
"A" represents a discharge current , "10.0" is displayed as the discharge current value .
2 , the total voltage
"U" indicates battery voltage , three digital display voltage range of 00.0 ~ 99.9V.
3 , single battery voltage
The first digit indicates the battery code , followed by three numbers indicate the single ( This only ) battery current voltage.
"1 ." Said the bird and the detector is connected to the battery positive , "2 ." , "3 ." , "4 ." , "5 ." By order of connection on.
4, the time
"H" represents the discharge time , in minutes , three digital display time ranges from 0 to 999 minutes .
5 , the capacity
"C" indicates that the battery capacity , the unit is safe when (AH), 3 -digit display capacity ranges from 0 to 999 Ah (AH).
6 , fault display
"Err1" temperature fault . Detector discharge process , if the temperature inside the detector , the detector will terminate the discharge , the discharge termination voltage is measured when the battery discharge time , the discharge capacity of the data is automatically saved , and the digital display flashes "Err1 . "
"Err2" battery voltage is too high for the test failure . When the detector 's red, black clip and battery positive and the negative turn , if the battery voltage is above 75V, the detector will display "Err2".
7 , reverse polarity protection : The machine is equipped with reverse polarity protection function, when measured detector with battery positive and negative polarity is reversed , the digital display is blank , the detector without any reaction.
8 , the end of the status display : detector detects the measured battery voltage is lower than the total termination voltage to automatically stop the discharge end of the discharge process , the digital display will blink test cycle battery total voltage , single battery voltage, discharge and the total time the battery capacity.
Key Description
"Start & rdquo key : in the ON state of the battery pack , press the" start " button to start working in order to display the detector discharge current , battery voltage, the single cell voltage , discharge time , the battery capacity .
" Search" button : In the switched battery status ( before starting ) , press the data "Query " button to query the last discharge at the end of the detector . Digital display in the query letter front , with the reverse order of the operating display discharge detector .
Instructions for use
1, the first battery tested to ensure each battery is fully charged . The detector red, black clips were connected to the positive battery pack , the negative column , detector digital display will show the total value of the current measured voltage battery pack . Then the sampled voltage on the line interface termination detector data interface , the other end respectively connected to the four clips ( clip regardless of the order 4 ) to the battery positive second to 5 (when the battery pack is the battery 4 should last a clip on the battery negative on the first four ) , specific wiring may refer to " real battery capacity detect wiring diagram ." Finally, open the clamshell case digital display , press the " start" button , the detector began to test battery discharge testing.
2, the detector to work , constant current of 10A to the battery pack of the measured discharge current digital display discharge cycle , the current value of the measured battery voltage , the voltage of each battery current , discharge time and the discharge capacity .
3 , the detector detects when the battery voltage is lower than the measured voltage to the termination , the detector will stop discharging , the discharge end of the process . Digital display will blink discharge cycle test battery termination voltage , single battery discharge voltage , the discharge process to complete all the time , the measured discharge capacity of the battery pack . Meanwhile, at the discharge end of the detector will automatically save the above data . When the battery pack can be turned in the next , through the " Search" button to search.
4 , wants to stop the discharge process , disconnect the positive and negative terminal of any one clip , the detector will stop working. Detector will automatically save the last discharge process parameters displayed .
5 , for any reason stop halfway detection must be re-charged before testing.
Caution:
1 , each folder must clamp connection real . For the application of the old battery before connecting water, steel brush to scrub clean fully , if the wiring connected to the virtual folder , the detector does not work or detect midway stop working.
2 , using high-power detector internal discharge resistor will produce higher temperatures , therefore, must be placed on the ground level of a well-ventilated detector work , and avoid the sun and rain .
3, the discharge operation , should grasp with both hands while the battery positive and negative battery clamp , to prevent the risk of electric shock.
4 , when the detector fails, by professional electronic repair technicians , and in power-down state .
Failure Analysis and Troubleshooting
Symptom Cause Solution
Digital display flashes "Err1" bad fan ; poor ventilation. Replace fan ; improve ventilation environment.
Digital display flashes "Err2"
Battery pack over five batteries ;
Charging the battery is being charged or immediately after .
The battery pack will be reduced to five test battery ;
Stop charging stand for 4 to 5 minutes .
Boot no reaction red, black clip lines reversed ; battery cable clamps or discharge line is bad . The red, black clip upside down position after connection ; cable or discharge the battery clip wire to reality.
No electricity is done automatically shut clip line is bad ; old battery or battery pole clamps serious corrosion . The wiring clip then real ; scrub cleared corrosion .
