1、 Product introduction
The function of the test instrument is divided into three parts: DC electronic load mode, battery production test mode and battery aging mode. Therefore, the equipment can be used as electronic load, aging cabinet and comprehensive test instrument.
Specific test items are: test voltage, internal resistance of battery, overcharge protection current, overcharge protection current, short circuit time, battery capacity, barcode input (SN) of infrared scanning gun.
Production and test of power electric bicycle battery, backup power battery, electric motorcycle battery and other lithium batteries. This equipment has the advantages of fast test speed and high test precision, so it is suitable for mass production test.
2.1 no load voltage
Lithium batteries and non - charging and non - discharging, positive and negative extreme voltage, also known as static voltage
2.2 battery voltage during charging
Under a certain charging current, the charging current is constant, and the positive and negative voltage of the battery can be set at this time. The charging time can be set
2.3 battery voltage during discharge
Under a certain discharge current, the discharge current is constant, and the positive and negative voltage and discharge time of the battery can be set
2.4 internal resistance
AC internal resistance of positive and negative circuit of battery
2.5 overcharge protection current
The maximum current is 60A, which is mainly used to test the charging protection current of the protection board
2.6 over discharge protection current
The maximum current is 100A, which is used as the electronic load to test the discharge protection current of the battery
2.7 short circuit protection time
The positive and negative electrodes of the battery are directly short circuited, the internal resistance value of the short circuit is within 10 milliohm (the external lead of the test instrument), and the reaction time until the protection of the straight circuit battery
Voltage range (0-100V) accuracy 10mV
Internal resistance range (0-2000 milliohm) accuracy 0.1 milliohm
Overcharge current (0-60a) accuracy 0.1A
When the over discharge current (0-100A) and the maximum voltage are 100V, the maximum current output is 100A and the accuracy is 0.1A.
Short circuit time (0-2ms) accuracy 1US
P + P-C -, select the corresponding test line according to the battery interface during the test.
If the battery model has only p + and p-output ports, it means that the battery is charged and discharged at the same port, only p + and p-wires are used to connect with the battery. If the battery has a C-Port, it means that the battery is charged and discharged at different ports, connect the three wires one by one with the battery
