2.4 Loading-discharge technology BSMS

2.4.1 based on the voltage across the load and discharge management A1175 MacBook Pro 15 inch battery

On the basis of load current and Technology discharge voltage can be simply described as follows:

The charging voltage CPU + ΣI ≤ ΣE? RX + ΣI? ΣUJ RO + (3)

Discharge voltage UC1 ≥ ΣE - (ΣI? RX + ΣI? ΣUJ RO +) (4)

 

Specifications of the current charge and discharge are based on the voltage across the battery to adjust the load current. Available as the constant current load, multistage charging constant current, constant voltage, constant voltage current limit, and derivatives resulting from a variety of debit, smart devices are pricing based on the charging voltage terminal-type discharge technology. The inconsistency of such equipment to suit the characteristics of the battery is extremely poor and can not be applied to the common lead acid, etc. rich liquid class of non-battery charge and discharge sealed can not meet the requirements for a balance of high-power lithium-ion and other new requirements.

Charge the battery only and flow based on the strategy of extreme technical skill and the following priority:

The highest priority: until the battery voltage control terminal monomer in the specified scope;

 

Second priority: voltage across the battery under control within limits;

 

Third priority: the maximum temperature must be less than or equal to the maximum allowable temperature;

 

Lowest priority: the load current must be less than or equal to allow the load current;

 

On the basis of the extreme single battery charge and control technology for the implementation of successful research to develop new lithium-ion power battery charge and discharge device with a new generation foundation. After the technology to optimize, improve and improve, we are now with the maturity of engineering applications. PA3399U-2BAS PA3399U-1BRS

 

2.5-battery system for evaluating the quality of the site

 

Applying the power of lithium inevitably involve ordinary end users. The power of the lithium complex structure of the technically demanding and high maintenance battery to advance higher requirements. Most existing electrical battery of tests is for scientific research institutes, large and medium designed for the needs of the production process is expensive, the use of the complexity of the technical quality customer specifications. Applicable to the user on the site of power lithium battery system of quality assessment is the driving force to promote large scale application of lithium batteries that must be addressed in supporting technical conditions for the Maintenance and foundation management. PA3399U-2BRS PA3465U-1BRS

 

Mechanical Science and Research Institute at the end user demand for battery care and management objectives successfully developed the user-driven on the power system battery location of the assessment system quality. The system is integrated into management systems battery to collect and record data support system, using the platform of data processing power, brought an inexpensive, easy to use, the battery applied to the end of the system Assessment of the quality of the user. The system performance of the assembly of the battery charge and discharge corresponding to the system performance and battery assembly for rapid assessment of the situation, etc., to provide users with reliable data at support of maintenance and management, and provides up to 8 batteries with the algorithm set of tools.

As users of the system battery power system to fully utilize the actual operating conditions in the automated data collection and recording, without expensive equipment and the load-discharge simulation equipment, has a very good price. System structure in Figure 5.

 

With the value of the static tension obtained by different sampling points, BSMS systems collect and record the conditions of the operating system user data battery voltage, in essence, is reflected in actual Working under the condition of the battery monomer EMF, resistance, electrical connection, charging status, air temperature and many other complex factors, known and unknown characteristic parameters of integrated features. User maintenance, no special analysis of relevant factors. Instead, the analysis of specific factors may cause unpredictable errors. The direct use of these parameters characterizing the cell system to assess and group, but the greater accuracy and credibility. Satellite M105 battery Satellite M40 battery

 

With characteristic parameters of the battery is relatively poor and the standard deviation on the balance of the battery (including the electromotive force, resistance, electrical connection, the state of charge on the battery performance such the impact of all factors) the assessment may be an accurate assessment of the battery system performance, the actual operating conditions and respect for users. Meanwhile, the real work to be automatically collected data on each single cell, the same battery system at different data and data from different battery systems have good reproducibility and comparability. Battery systems for assessing horizontal and vertical quality of the comparability of data sources provided the foundation.

 

The successful development of the system to provide users with a set of very low cost for the daily management of the power tool battery system for assessing quality, battery and load equipment selection and discharge of basic maintenance. Satellite M45 battery Satellite M50 battery

 

2.6 lithium battery power test system group

 

The system is mainly used for energy production and use of lithium batteries during the load tests, experiments discharge conditions pricing simulation, set analog electrical conditions, according to the characteristics of packet data corresponds to the power of lithium batteries.

 

The system structure of Figure 6, has three modes: Intelligent loading and unloading mode control packets, the conditions control mode. Version to provide linear and nonlinear group group, which has nine kinds of linear block grouping methods to choose from. Satellite M55 battery Tecra A3 battery

 

Energy lithium battery system test packets, using “Based on the extreme single cell” technology to control charge and discharge, can load and unload effective security controls, combined BSMS collection methods data and has a unique feature of the platform packet processing site focused on Power Lithium battery system test packets, simulating actual working conditions under the state of battery charge and discharge conditions can be grouped in the battery separator has a good consistency of matching sets of batteries, battery manufacturers at the last address of the battery, inconsistency program.

 

In Figure 7 (a) for the 108 batteries in running, Figure 7 (b) that the curve of error of 0.5% in group situations. The battery is divided into three groups: a type of cell in which a total of 41 type B were 3 batteries, battery type C 1. Inspiron 9200 battery Inspiron 9300 battery

  

(1) of the complete life cycle considerations, the battery life of lithium was less than the common lead-acid. Energy Industry of the lithium entered the large construction industry and promote the use of a new historical stage. Power Li-ion in a group of applied technology and research facilities is the development of the energy industry’s current lithium battery, an important issue.
