Battery power supply design is the development of chemicals and the workers of scientific research, Hp laptop battery technical staff, knowledge and skills.
1. Battery Design Basis
• The design goals of battery and the basic principles of
Cell is the design of instruments and equipment to provide the best use of the performance of work or power outlet. Therefore, the design of the Laptop battery must first be used to meet the electrical requirements and optimize it with the best overall performance, to determine the battery electrode, electrolyte membrane, Shell and other parties parameters, and they are hand are made to specifications and indicators of battery or batteries.
• design of the battery requirements
Battery is designed to meet the object (or user equipment) made the request. Therefore, when designing the battery, the first to have a detailed understanding of the items on the performance indicators of the battery conditions and user requirements, generally include the following:
• the battery voltage;
• Battery operating current is the normal current and peak current;
• Battery working hours, including time to discharge continues,Hp laptop battery HP F4098A Battery, HP F4809A Battery, HP F4812A Battery, HP 319411-001 Battery, HP Presario 2100 Battery(compaq 2100 Battery), the use of the term or life cycle;
• Battery work environment, including hours of work in which the Dell Latitude D510 battery status and temperature;
• The maximum size of the battery.
Should also be taken into consideration: the source material; battery performance, HP F4809A Battery characteristics of the battery of the determinants of battery technology, economic indicators, environmental issues and other factors.
• performance assessment battery of key indicators
Battery performance in general, mainly the following aspects to evaluate.
(1) The capacity of the battery capacity is defined as a rejection of certain conditions, can be obtained from the battery power, which is currently on full time, generally expressed in Ah or mAh, this which directly affects the maximum operating current of the hp Pavilion dv4 battery and working hours.
(2) The discharge characteristics and internal resistance characteristics of battery discharge is granted the discharge of the battery in a system, the fineness of its operating voltage, the voltage level of the platform and the performance mainstream discharge, etc., which indicates that the battery with a capacity load. Battery internal resistance including the ohmic resistance and polarization resistance electrochemical discharge current large, the resistance of the flow characteristics are particularly evident.
(3) Operating temperature with electrical work environment and conditions require the use of batteries in a specific temperature range with good performance.
(4) The storage performance of the storage sony VGP-BPS5 battery for a while because of certain factors for changes in performance,Hp laptop battery HP F4098A Battery, HP F4809A Battery, HP F4812A Battery, HP 319411-001 Battery, HP Presario 2100 Battery(compaq 2100 Battery), causing the battery to discharge, leakage of electrolyte, the battery short-circuit and so on.
(5) life cycle (secondary battery) life cycle means the system of secondary batteries in accordance with a certain load and discharge its functions reduced to a certain level (for example,HP F4812A Battery the initial capacity of 60% ) when the number of cycles.
(6) The internal pressure and resistance performance overload (secondary battery) for Ni-Cd, Ni-MH battery and other sealed type secondary, high current for recharging the battery internal pressure can reach the balance and equilibrium pressure of the high and low resistance of the battery current level of overcharging to measure the performance of performance are all important indicators of good or bad, if the battery internal pressure reaches the equilibrium or balance, the pressure is too high, it will limit the devices battery voltage (such as explosions bullet proof) to open the battery caused by discouragement or neglect fluid, which leads rapidly to the failure of the battery. If the device fails, pressure limiting, there may cause cracking of the tank apple iBook G4 14 inch battery or an explosion.
2. Battery design the basic steps
Battery design staff in design tasks clearly and fully prepared, you can imagine.
User requirements depending on battery design ideas from the battery, there are two: Hp laptop battery HP F4098A Battery, HP F4809A Battery, HP F4812A Battery, HP 319411-001 Battery, HP Presario 2100 Battery(compaq 2100 Battery), one for electrical equipment and instruments, rated capacity of the power source, and another is just one factor given power supply form developed excellent battery performance specifications for new or special-shaped battery.
1 to determine the ability of design steps of the battery
• determine the number of combined organ cells Tenor battery voltage of single battery and current density.
• According to user requirements to determine the overall work of the battery voltage,HP Presario 2100 Battery current indicators of operating and other series of selected cells, the light of the series “Volt-Ampere curve “(derived from empirical data or experience) to determine the work voltage of single cell and current density.
• determine the number of batteries in a single cell.
= The number of total voltage single battery voltage / battery
• Calculation of battery capacity
• According to the requirements of course work and working time calculations of charge.
Nominal Capacity * = current operating hours
• determine the design capacity of
Design capacity = capacity * Design factor
A design factor is to ensure the reliability and lifetime of the whole of the battery, the general attitude 1.1-1.2
