digital batteries

1 Introduction

 In recent years, the rapid development of portable electronic products for a replacement battery technology. Lithium-ion batteries because of its high energy density, long life, low self-discharge rate, no pollution and other features, quickly becoming the market mainstream battery products. Appeared to prevent the battery charge or over discharge state to ensure the battery’s safety performance and to avoid deterioration of battery characteristics, must be installed in lithium-ion battery protection circuit. Inspiron 1300 Inspiron 1420 While lithium battery can provide reliable power for the device, for detection and monitoring of smart batteries that must be considered link. Lithium battery-powered portable devices in modern power supply the most appropriate solution, but the charge and discharge is less secure than nickel-cadmium batteries, nickel metal hydride batteries and the traditional power of ordinary disposable batteries. If the charge and discharge the right way, will lead to lithium battery safety problems occur, or even an explosion, it is necessary to add lithium battery monitoring circuit to real-time monitoring charge and discharge process. Taking Actions to design lithium battery SOC chip ATJ2085 external detection system, the design of programs to control various functions of the microprocessor as the core, in addition to lithium-ion battery pack provides over charge, over discharge, over-current protection, the Can also be effective on the lithium-ion battery pack lithium within the single charge and discharge protection to provide a balanced, real-time detection of lithium battery in which the state and protect Inspiron 1501 Inspiron 1545 Inspiron 1520 .

 CU and 24-bit DSP dual-processor architecture, the respective events for the control and operation of multimedia data encoding / decoding system-level optimization, through the digital-analog mixed-signal technology, in a single silicon integrated high-precision ADC / DAC converter , USB controllers, real-time clock RTC and so on. Support USB2.0 (FULLSPEED), media player and other formats supported MP3/WMA/WAV/WMV/ASF; Support MTV movie player; supports JPG, GIF, BMP picture browsing. The system is highly integrated, the external application circuit is simple, has a fully functional and mature development tools and environments Inspiron 1564 Inspiron 1720 .

Recently, GE Global Research Center announced that its hybrid power system R & D team successfully developed a dual-battery system, the application of this new system will speed up the transit buses, freight trucks and other large vehicles in the electrification process, and is expected to reduce the cost of the battery 20 %.

    Consists of 25 scientists and engineers in the GE Hybrid Power System R & D team successfully demonstrated a high capacity of sodium from the high-power lithium batteries and driven by the zero-emissions two-cell hybrid buses. Located in Zhangjiang, GE China Technology Center participated in the two-cell system research and development  B141EW02 B141EW03 B141EW04 .

    Today, most types of battery power in terms of capacity and are difficult to be reconciled. Li-ion battery can provide a strong impetus for the vehicle, but the capacity is low; and sodium batteries on the contrary, it can store large amounts of energy, but not prominent in the power area. With the increasing improvement of battery technology, how to further reduce battery costs and reduce the battery size is the electric vehicles can be widely used in the key .

    GE’s scientists believe that for large cars are concerned, both high capacity and high power dual battery system in a reasonable range of size and cost while achieving rapid acceleration and long-distance driving requirements. Newly developed dual-battery electric bus, the two play out their respective strengths: lithium battery for the vehicle acceleration and braking to provide a high-power, and sodium batteries for automotive vehicle provides a constant power. At the same time requiring high power and high capacity buses, trucks and other large vehicles using the dual-battery system, not only can improve vehicle performance, but also can reduce up to 20% of the battery cost B141PW01 B154EW01 .

    This project is funded by the National Fuel Cell Bus project funding is up to $ 13,000,000 as part of research projects, from GE and the Federal Transit Authority (FTA) and the Northeast Advanced Automobile Federation to work together to complete.

    GE recently announced Financial Group through its car rental business in 2015 to purchase 20,005 thousand electric vehicles. GE in 2011 purchased 10,002 from the thousands of GM electric car. The Chevrolet Volt car purchase plans from the beginning, and then will be expanded to other car manufacturers electric car models B154EW02 B154EW04 B154EW08 V.0 .

    Recently, GE promised in the next 5 years to green technology R & D investment of 50 billion U.S. dollars to 100 million.

Reporter learned from the Henan Provincial Government, Henan Province recently introduced the electric car industry development programs and plans in 5 years, electric cars built in central China manufacturing center.

 This has begun to implement the main tasks of planning, including the Henan Province of China playing a major electric vehicle research and development center, the domestic first-class production center and the domestic battery of important influence in key parts production center.

 Henan province through the promotion of new energy vehicles, energy companies and auto makers and new strategic restructuring, competitive advantage, increase research and development efforts to support as soon as possible breakthroughs in key technologies, the establishment of special funds and a series of industry measures to speed up this goal Implementation.
