Researchers use neutrons for battery optimization

Materials: With neutron scientists are looking at the research reactor FRM II in Garching during charge and discharge into the interior of a battery cell without opening them. Because if you know how the metals and chlorides are distributed inside and change, can be efficiency and lifetime of a battery cell, a positive way. VDI nachrichten, Munich, 12 2. 10, Si

Those who previously wanted to study a rechargeable battery, had to cut their case circumstantially. This content may not change following the sudden penetrating moisture and air. Neutrons, however, it allow non-destructive to look into the interior of a battery. At the two instruments Stress-Spec and Antares the research neutron source (FRM II), TU Munich, scientists analyzed why a battery cell in the U.S. technology company General Electric (GE), Fairfield, Connecticut, without opening the cell.

The sodium-nickel chloride battery once to come in a hybrid locomotive, GE Transportation is used, which is powered by a diesel engine and batteries. The high temperature cells are operated at a working temperature of about 300 º C and recharged during deceleration of the locomotive. The output voltage is 2.58 V per cell, the energy density is 100 Wh / kg and 120 Wh / kg. Ideally, the technology group expects around 10% less emissions than a diesel-only engine.

GE scientists were at the FRM II, and an unloaded half discharged battery cell to investigate the charge and discharge process. On Anatares instrument (Advanced Neutron Tomography and Radiography Experimental System) took the physics and chemistry using the neutrons that pass through the battery casing, a radiography of the interior of the cell. It was false, with the level of sodium in the battery profile, which reacts during the discharge of sodium chloride. The less sodium in the battery, the more draining it is.

On residual stress and texture diffractometer Stress-Spec investigated the Munich scientists at the neutron content of the battery prototype from GE. Here they took advantage of the different reaction of the materials in the battery with neutrons to determine which chemical substances in the cell are distributed in what density. That, say experts, is important to know how the battery cell, as often false and can be unloaded.

The result confirmed the expectations of Munich researchers: The concentration of the metal as an important reactant loading in the battery is high on the sides and falls off toward the middle, as with their measurements on the stress-Spec noted.

GE now plans to cooperate with the scientists of the FRM II, the first time to observe a battery during charge and discharge process with neutrons. Thus one could watch the process of how to change the distribution of substances inside the discharge over time, and soon develop batteries that supply an engine as long as possible with the necessary electrical energy.

Master Control Unit design and implementation: Master Control Unit is microcontroller PIC16F873 and keyboard controller chip ZLG7289A composition. The main task is responsible for communicating with the different costs today, and the processing of user input and LCD display information. The keyboard controller chip in here for six buttons and 12 LED control. ZLG7289A with a microcontroller through the SPI bus between the two-way communication. Main control unit charge per check every time unit, to obtain information about the current charging unit, as there is no battery, battery properties, the battery voltage. Followed by the LCD module to the user.
Design and Implementation of Charging Unit, LTC4002 Li-Ion Battery Charge Controller: LTC4002 is a high efficiency switching independent lithium-ion battery controller. The manager has two versions of 4.2V and 8.4V. LTC4002-8, 4 has a 500kHz switching frequency, is a high efficiency current mode PWM controller. This is an external P-channel MOSFET drives, it can provide 4A of current costs, while the efficiency can be as high as 90%. Output voltage is set at 8.4V, the final drive voltage with 1% accuracy, while the 5% charge accuracy. Furthermore, the handset can be 9V ~ 22V wide variety of wall adapter to run. In comparison with the hysteretic topology chargers, LTC4002-8, 4 of the fast operating frequency and current mode architecture to enable the use of small capacitors and inductor / capacitor combinations.
Lithium-ion / Ni-Cd battery loading unit of the overall design of the dual use: LTC4002 the face of an analysis of the past can see, the chip is for the lithium-ion battery controller, the nickel-cadmium batteries need to address the following issues: First, LTC4002 to monitor the battery voltage to ensure that the battery voltage does not exceed 8.4V. But for nickel-cadmium battery pack, charging cut-off voltages up to 9.2V. Secondly, the nickel-cadmium batteries come to an end, the need for batteries in the normal current 30% and 10% of the droplet charge. Thus, the second problem to be solved is how the size of the constant current charge current control. Moreover, nickel-cadmium batteries to charge pulse mode. Namely, 1s cycle, 95% of the time to 1% of the time charged the remaining time for the output is not paid leave. Finally, the court that a lithium-ion battery battery or nickel-cadmium batteries, lithium-ion batteries because if the miscarriage of justice for the nickel-cadmium batteries, will charge voltage higher than 8.4V, this lithium-ion batteries is very dangerous, but will nickel-cadmium batteries for lithium-ion battery miscarriage of justice, it may lead to insufficient battery loading. Therefore, we must ensure that a very low false positive rate.
The LTC4002 works partially based on the design of both the lithium-ion battery constant current - constant voltage load, they can nickel-cadmium battery pulse charging system. Charging the unit’s overall functional block diagram shown in Figure 2. Among them, signal-conditioning circuitry to both charger for 8.4V lithium battery load, but also may be 9.2V Ni-Cd battery load, but also play a role in controlling the size of the load current. LTC4002 use of micro-manager control work state, with the redundancy circuit that nickel-cadmium battery charger can be off loaded from pols run. Micro-controller through a certain communication protocols (HDQ16) and intelligent battery communication, to determine their capacity, the chemical nature of the key parameters.

Laptop battery using tips

This blog post via: Laptop battery using tip.
Should we remove the battery when the laptop powered by Household Electricity?
Do not remove the battery when using the AC adapter. If your area have no steady voltage or electricity, a sudden power failure happend when you at work, the work you have done lost and the machine may also burn motherboards without the battery protect.
Notice when charging
Usually used when the battery discharges to 10% of charge can be carried out, do not discharge to 0% every time before charging. In general the battery will be fully charged in 2-3 hours with machine shutdown , 4-5 hours with machine using. IBM’s notebook can not charge at 95% , COMPAQ laptop in about 90% before charging, this is designed to avoid the repeated charge and discharge damage to laptop. Requests depth of discharge once a month : discharge to 5% of the time , shut down the machine to re-charge. “Note - Do not let the battery completely discharged”. Remove the battery if do not use battery for a long time, please charge the battery to 50% before store.

Why do laptop batteries consumed when laptop turned off and cut off the power supply?
please see the following reasons:
1. The computer shut down, the laptop battery will provide power for RTC functions.
2. The power switch is not only the power line switch, but also the management control of power supply switch, the signal sent to the power switch function.
That is, the management of the power supply controller connecting the battery and power adapter has been a state power, so electricity consumption.
Micro-computer circuit to run, even send a message will consume battery power.
VAIO batteries, not just the battery, but also added to monitor the battery status (battery remaining capacity and charge and discharge current value, the temperature of the battery group, etc.) built-in micro-computer, and at regular intervals Send a signal to the computer functions.
Therefore, loading the battery in the computer will definitely consume electricity, even put out there will be a natural addition to discharge outside the electricity consumption. Thus, even cut off the power supply, battery consumption is normal.
