the secondary development of implementation strategy
First post by: www.itsbattery.com
Now used in most of the charger to the Compaq Presario 1700 Battery charge when they were both using low-current charging method uses the rated charge current methods, that is, the volume charge, low charge current is usually used in the initial stage of charge. At this stage, the required charging process will result in the termination of the initial chip self-heating effect to minimize the extent of the volume charge is usually used in the intermediate stage of charging, the battery most of the energy is stored at this stage. In the final stages of battery, charging time is usually the vast majority of these were consumed at this stage, you can monitor the current, voltage, or both values to decide when the end of charge. Similarly, the end of the program depends on the chemical characteristics of the battery, for example: the majority of Li-Ion battery charger to the battery voltage is maintained at a constant value, while the lowest current detected. Ni-Cd, NiCd latitude cpx battery voltage or the rate of change of temperature to determine the end of charging time.
Charging part of energy is converted into heat, until the Compaq Armada E500 Battery is full. And filled with all the energy will all be converted into thermal energy. If at this point does not terminate the charging, the battery will be damaged or destroyed. Quick Charger battery (fully charged in less than two hours of the charger) you can solve this problem, because these chargers are using high charge current to shorten the charging time. Therefore, lithium-ion battery, the monitoring of its temperature is crucial, because the latitude c600 battery will be recharged during the burst happened in all stages of the charge should be ready to monitor the temperature and the temperature exceeds the maximum set value immediately stop charging.

Charging circuit consists of three parts: the control part, test parts and charging components. As shown in Figure 1, using F310 Singlechip for charge control, microcontroller itself PWM pulse width modulation type switching power supply required for full functionality with 10-bit A / D converter. The use of single-chip A / D ports, constitute a latitude c610 battery voltage, current, temperature detection circuit.
Single-chip voltage feedback and current feedback signal, the direct use of digital PWM output voltage signal and converted into analog voltage signal, can guarantee control precision.
PC configuration information will be sent to the Apple Laptop Battery controller, the controller will determine the identification and classification of information stored in the soft partition configuration EEPROM module, and then the main program from the EEPROM by the DSP has a fixed address in the classification of good calls. PC upgrades in the configuration information on the equivalent of changing the data stored in the EEPROM in order or size. The system uses the EEPROM space size 64kB, the data storage area of each page has 32 bytes (0×0000-0×0031), can store 256 (0×0000-0xFF00), each page can store a configuration information.

Configuration in the controller port upgrade process, the host computer to configure terminals and controller configuration software module for each hardware port synergy definition constitutes a mapping model (Figure 4). The so-called abstract model can be mapped into such a mapping function, that is, f: x → y, in which x and y are two elements collection, where can be expressed as controller hardware port number and the actual application functions, f dell 5081p are x to y of a map, are variable, the mapping through the medium of EEPROM and save to the performance. Each PC to send a new port configuration, f to change once the new hardware port functionality is also changed accordingly. For example, the first way the original controller A / D interface is set to the initial “acquisition into the reactor temperature signal”, the second path A / D is set to “collect a heap temperature signal,” “the first path” and “second way” mapping model is x, that this is a hardware controller serial Laptop Battery port; and “into the reactor temperature” and “out of stack temperature” is the host computer to configure the y, that the practical application of port functions; and f while the two linked together, express the x to y of the mapping relations. When the host computer to the way the two A / D interface to exchange configuration, f is also the corresponding changes in configuration of the result is the “first road” A / D port into “a heap temperature signal acquisition,” “The second path” A / D-port will be turned into a “collection into the reactor temperature signal” the.

PC completed the job controller configuration, the configuration module in soft upgrade all of the information corresponding mapping model is set up has finished, when DSP engines through the implementation of the various mapping model will be called to the main program module corresponding procedures . Execution engine is an express configuration information than the higher-level mapping model of the mapping model, the same token it can also function as an abstract mapping f: x → y, here, x refers to the soft upgrade module configuration information mapping model, such as A / D port mapping model, I / O port mapping model, since the mapping model shutdown conditions, sensor calibration mapping model; and y is the main program in the implementation of this part of the procedure to upgrade information dell laptop battery module, f is complete mapping model corresponding to the program execution module Apple A1175 Battery mapping.
Secondary development of fuel dell 710m battery cell engine control system Another feature control strategy lies in its diversity. Traditional control systems for the purposes of a single control object is usually only one type of control strategy, in the control process or function can not satisfy the user needs to expand, sometimes in order to meet the needs of different control objectives and procedures and even had to re-programmer to redesign the controller. Figure 5 shows, the system host computer through the soft switch controller integrated strategy for the Treasury, it will be convenient to use a wide variety of control strategies for fuel cell engine dell f5136 control. Choice of control strategy has the normal operation of the overall system coordination and control Apple A1185 Battery strategy, the system normal operation of local coordination and control strategy and system of partial failure of running coordinated control strategy. A variety of alternative control strategies to a large extent of the control system to meet the different needs, and its simple and friendly man-machine dialogue.
In this paper, according to the secondary development of fuel cell engine system functional requirements, design a controller for the soft-configuration and the corresponding secondary development of the upgrade mechanism, controller ports on the internal structure and control system operating parameters of the secondary development of the upgrade. This paper also proposed a fuel cell engine control system to coordinate the performance of many control strategies, and in the control system to carry out a preliminary exploration. Practice shows that the control Apple M9324 Battery system is running stable, reliable, and obtained a good control effect.
