One by one, to feed test signals into a single cell, without requiring the entire battery in high current, there was no connection to the DC system external interference. Bipolar test signal using the original algorithm is modified, but the results show that the reliability of the signal pole. However, when tested with a unipolar signal, the DC drift. Easy to eliminate this drift and can not maintain all data features, which is characterized by precise determination of parameters needed. Use of frequency scanning signal pulse method rearrangement of different frequencies (including the test signal), allows the response of the battery voltage curves coincide with the book.
Once the curve derived from the potential to become a rule, you can set the firmware algorithm that style drift and eliminating it and thus be suitable for direct input algorithm Sentinel, the average zero-sets of data voltage. This method can be reduced to the drift error of 0.1%, it will not cause a significant distortion of the data sets. Therefore, measurements of signal can also be used in the algorithm, so that the accuracy of equivalent circuit parameters above. Vostro 1310 battery Vostro 1320 battery
Dealing with many measurement functions and algorithms have been integrated in a monolithic integrated circuit. Sentinel module can measure a single monomer battery, also measured on all 12V battery). Up to 250 measuring points are the forms module for measurement, the measurement results can be submitted by a data bus dedicated to the battery from the data recorder, S-Box. In large systems the battery may be a few stocks such as data flow synthesis, which is a management system locally or remotely, can make use of the S-Box in the embedded web server through a bus standard or an Internet connection to use these data streams.
SOC by using measures to determine the actual status of each battery can not only provide fault detection, near this sophisticated monitoring framework will be able to have functions; can also configure other functions and services. Vostro 1400 battery Vostro 1510 battery
For example, the battery internal resistance within a single cell is usually different. Over time, this state will be a problem. SoC intelligent control system can quickly detect this single cell, the terminal voltage optimization system can be transferred can not continue to charge a single battery floating around the news…
Real-time charge management can extend the battery life: In the voltage across the same situation, VRLA battery float in the current ratio flooded high-tech batteries. This may accelerate corrosion of the anode plate, which reduces the effective life of the battery up to 30%. On the life of a certain percentage of the float can be reduced to eliminate this bad effect. However, these side effects on the life cycle is also an advantage is to reduce the incidence of thermal runaway.
Installing a battery pack can also provide the full life cycle of the voltage and temperature records, that manufacturers and users use. Vostro 1520 battery Vostro 1710 battery
Over-discharge protection cons: the device in the charger / UPS systems are common, especially in the battery monitor, they are based on the average voltage of individual cells of the termination of the landfill to protect the battery. However, the poor performance of the voltage across the battery may be much lower than the average voltage in the battery, but also in its termination voltage is reached before the landfill was good. Therefore, the development of a dynamic high-accuracy ‘Time to Run (outstanding Running)’ algorithm, in any single cell will be depleted when an alert is given.
Monitoring of battery backup required parameter as detailed as possible in order to generate the most accurately reflects the results of the battery status. This is not just a technical problem, is also an economic issue. Avoid battery failure is essential, but replaced prematurely and did not even approach the end of the battery life is extremely profitable. In addition to the measurement of each battery voltage, impedance and discharge performance, LEM will also measure the internal temperature of the battery is defined as a standard feature, is a leading global position. LEM is currently developing a magnetic flux sensor technology is to float, with a resolution greater than 10mA, with little or no drift in temperature, high discharge current with almost no residual magnetism, measurement repeatability better quality. The integration of these advanced features, the battery monitor is more expensive systems, but the overall life of extreme cost-effective management system. Vostro 1720 battery Vostro 2510 battery
