Discharge can be adjusted to constant current discharge Online function, connected with computer through USB interface, the upper computer can monitor the work of the instrument. Adaptor Input 100～240V, Output 24V 2.65A Display Segmental LCD with white backlight + red and green monochrome LEDs Discharge mode Constant current discharge, default 500mA, maximum 1000mA, discharge current can be set by BM (Battery Manager), external electronic load, maximum discharge current can be increased to 3A. Charging method Mainly Constant Current + Constant Voltage (CC+CV), and depending on the battery voltage, it may also include activation and pre-charging. Activation: When 0V battery is connected to the instrument it may not be recognised, pressing the charge button will start the activation function. When communication with the battery is restored, the battery is activated and automatically transferred to normal charging. Pre-charge: Pre-charge when single cell voltage is lower than 3000mV. Constant current: Fast charging is performed when the voltage of a single cell is higher than 3000mV but lower than 4200mV. Fast charging flow varies according to the battery design capacity. End of charging: The current will gradually decrease when entering constant voltage charging, and the charging will end when the current decreases to the termination current, or the battery reaches 100% and the current is less than 1A. Charging current The maximum charging current is 2.5A. The current is related to the charging mode. The details are as follows: Design capacity, Pre-charge current, Fast charge current, Termination current ≧6000 400 2500 300 ≧3500 400 2000 200 Other, 200 1000 100 In particular, if (set_FastVol-bat_vol) < 400 when the battery is first connected, the fast charge current and termination current are calculated additionally, so as to avoid the initial current being too high and to ensure that the battery is fully charged. Standby power consumption ≤1W Operating Temperature 0-40°C, 20%-90% RH (Non Condensing) Storage Temperature -20℃-65℃, 10%-95% RH (Non Condensing) Time Charging time limit 8.8h; Discharge time limit 8.8h; Test time limit 20s+10s; // chg+disc (Charge+Discharge) Charge correction time limit 8.8h+20s+8.8h; // disc+pause+chg (Discharge+Pause+Charge) Function menu no key automatic exit time 10s; Charging is divided into several stages: activation, pre-charge, constant current and constant voltage. The initial charging mode of the battery depends on the starting voltage of the battery, and the charging process may not require activation and pre-charging. For charging mode and current, refer to ‘Charging mode’ and ‘Charging current’ in the ‘Basic parameters’ section. Natural end of charging One of the following conditions is met: 1. Battery level ≧99, current is 0. 2; 2、The power is full, i.e. rmc = fcc; the remaining capacity = full charge capacity. 3、Current decreases to the termination current during constant voltage charging; Additional condition for the end of charging: the power quantity reaches the set value. Discharge There is a discharge circuit inside the instrument to discharge the battery. The default discharge current is 500mA, you can set the discharge current through BM, maximum 1000mA. Dual load constant current discharge: Internal load: [0, 1000] mA continuously adjustable, set via BM; External load: [0, 500, 1000, 1500, 2000] mA available in 5 steps, selectable via dip switch. The end of discharge meets one of the following conditions: 1, Power ≦ set value; 2, Voltage ≦ set value; 3, Discharge to current 0. Attention: Discharge is constant current discharge, but there is a little deviation between the set value and the actual value, the specific value is related to the battery. Battery Test Test whether the battery charging and discharging function is intact by charging and discharging the battery for a short period of time. The time limit is 30s, after the test is completed, the LED flashes green and the LCD displays the result: Normal, LCD shows ‘Test OK’; Abnormal, LCD displays ‘Test NG\’\'. Possible reasons for abnormal test and countermeasures: 1. Battery voltage is low, resulting in discharge failure. Try to charge the battery, increase the voltage and test again; 2、The battery power is too high, resulting in charging failure. Try to discharge the battery, and test again after the battery clears the ‘full charge’ mark; Poor contact of the battery connection cable; 4, instrument failure or battery is bad.
