Battery charge and discharge detector

Battery charge and discharge detector
The battery charge and discharge detector produced by Shanghai Shunmeng Electronic Technology Co., Ltd. integrates charge and discharge unit detection, online monitoring and activation into a five-in-one machine. By conducting capacity tests on batteries, we can accurately and quickly find out-of-date batteries and give the remaining capacity of each single battery. Through activation, each battery in the battery pack can quickly and fully increase its capacity, reduce internal resistance, and effectively solve the problem of single cells. Body voltage imbalance phenomenon. Large-screen LCD display microcontroller control can detect or set parameters such as voltage, current, time, and capacity of a single or entire battery pack. The charge/discharge end data can be directly uploaded through the interface or transferred to a disk on site. The supporting data processing software can analyze the remaining battery capacity, display and print various charts to provide a scientific basis for analyzing battery performance.
Main functions and features of battery charge and discharge detector
Touch LCD screen display. Single-chip microcomputer control, full Chinese menu prompts, simple operation, convenient maintenance, and high degree of intelligence.
The machine adopts switching power supply technology, microprocessor measurement and control technology and digital temperature measurement technology with high integration and strong anti-interference.
The switching power supply control chip adopts imported military-grade integrated circuits, which is stable, reliable and has a long service life.
Low ripple coefficient, little interference to other equipment, strong air refrigeration type heat dissipation load, automatic load sharing, low failure rate, high reliability.
Using intelligent charging technology, constant current, constant voltage, reduced trickle and float charging, intelligent three-stage charging mode strictly follows the battery charging characteristic curve for charging. Utilizing pulse charging technology, each battery can be fully charged quickly, which effectively solves the problem. The phenomenon of cell voltage imbalance does not require manual supervision.
Parameters such as voltage, current, time, and capacity can be set to automatically complete the charging process of the battery pack.
The automatic stop function automatically stops charging when any of the following conditions is met. The charging time reaches the charging capacity and the protection voltage is reached.
Alarm and protection function If there is an abnormal charging voltage, abnormal charging current, high temperature, abnormal cell voltage, etc. during the charging process, an alarm will be prompted.
The calibration and correction function of the voltage and current display value can calibrate and correct the total voltage and current of the battery pack.
Intelligent cycle charging
Set the technical parameters of discharge or charge according to the actual detection status of the battery. The equipment automatically completes a charge and discharge cycle, thereby improving work efficiency. Parameters can be set on site or the battery can be operated by computer through or communication. During discharge, when the entire battery voltage or capacity reaches any alarm threshold, the equipment automatically stops working. When charging the battery, the device automatically stops working when the battery is charged to capacity or the charging voltage reaches any threshold value. Intelligent charging equipment has the following functions
The equipment has a constant current charging function
Constant current charging is performed according to the specified current, voltage, time, capacity and other parameter requirements to ensure the charging efficiency and charging safety of the battery. Constant current charging and constant voltage Charging is a trickle charge.
Verification discharge test function
Perform verification discharge test on the battery pack
>Remaining capacity test function
After completing the discharge work, the equipment should be able to automatically calculate the remaining capacity of the battery for maintenance work Provide reliable basis.
Activation function
The battery can be charged, discharged and activated according to the set parameters. During the charging, discharging and activation process, it automatically displays the battery voltage and current change trend. The battery charging and discharging capacity and the current and voltage change curve display function. The battery activation has a leading pulse activation function that can set multiple cycles to activate lagging batteries. (Separate charging and discharging can be set up to hours)
