Iron battery and BYD

September 6th, 2010

Iron battery

In the individual this view, BYD iron battery is most likely to achieve commercialization of disruptive technologies is very easy, because only it has not already available in other new technology enterprises and the cost advantage. At present, conventional lithium-ion battery charging time at least 4-5 hours, while the dual-mode electric vehicle charging stations in Zhuanye soon have full 15 minutes Ke full 80 percent, even in slow Chong Jia Yong power on it is merely necessary 9 hours can be filled.

Currently, almost all of the world’s major automobile manufacturers reserve the new energy vehicle technology and business plan, but we do not worry

In addition, Wang also from the battery and the success of IT experience in manufacturing a set of decoding can reduce the cost of the “Password”, he plans to replicate the same gene to the car manufacturing, play a beautiful low-cost production combination punches.

Previously, Wang said the dual-mode technology to master the world today, only GM, Toyota and BYD three companies, but General Motors, Toyota’s electric car can travel 25 kilometers on one charge, while BYD DM electric vehicle able to travel 100 km , while BYD DM car also broke repeated charge, household outlet for charging two technical difficulties, so that the electric car is more convenient to use. Such achievements are sufficient to arouse the attention of international automobile manufacturers, Toyota Motor (China) Investment Co., Ltd. General Manager Isogai Kuangzhi recently conducted a visit to the BYD Auto, it is known, the main trip is to examine aspects of BYD in electric vehicles technology and production.

BYD Auto Sales Co., Ltd. General Manager in summer ice had told “Fortune Times” interview, said the cost of dual-mode power system is 5 million yuan, annual production reached 200,000, the cost can be reduced to 30,000 yuan. A senior automotive commentators believe that, BYD only in battery technology and cost advantage both cases, the commercial electric vehicles as soon as possible, Wang proposed in 2025 as the first position Qiche manufacturers Mubiao Cai Zhen Zheng Kaopu.

Bet iron battery life

In summer the ice that had to do if BYD electric cars on impulse, then now is the electric vehicles as the ultimate goal of making. To be within reach of the target impulse, BYD which started the battery technology is indispensable bridge.

October 2007, BYD in Shenzhen to showcase the many years of research and development of its iron battery results – with one-iron battery-powered car officially unveiled F6DM. With traditional lithium-ion battery power, compared, Wang iron battery that such lower cost, higher security, and dynamic, thereby electric power car from the commercial even more so. “We have mastered the core technology for electric cars – iron battery, has 700 domestic and foreign applications for patents. Iron battery raw materials, extensive, non-polluting, recyclable, its heat resistance, resistance to stress and capacity are far stronger than the battery, the battery charge cycles up to 2000 times more battery life than the continued mileage 600,000 km. ”

BYD shares, said an engineer company, BYD battery power for the development of the feasibility of iron, built a more than 500 R & D team, in a few years to tens of thousands of tests and testing, ” iron battery in the car currently on the application of power, including security and continuity of ripe, but charging time is not very economic, but on other products of iron battery applications can bring considerable economic benefits for the BYD. “In iron battery technology is relatively mature, BYD is preparing a new battery factory, specializing in automotive batteries, plans to 5 years battery capacity of iron to match the 200,000 electric cars.

According to BYD Auto plans, future BYD models will fuel the development of all the same style of dual power car, for example based on the introduction of the F3 F3DM, based on the introduction of the F6 F6DM, while the ultimate goal is the introduction of E3 and E6 that pure electric vehicles. Production from the current layout view, F3DM production at its base in Xi’an, and Shenzhen Base F6DM is in offline, “We hope that through electric car to change the industry structure, the establishment of BYD in electric vehicle industry leadership.” Summer of ice, said. Technically, BYD in rechargeable battery industry and the world’s second-iron battery in both areas to ensure success could make it for the time being the lead in the cost, the cost of lithium iron battery 1 / 10, the relative Hybrid electric power than any other vehicle manufacturers a lower cost, while BYD inherent in the manufacturing chain, the cost of control move to electric cars can be flat areas.

Connector development

Connector development

Connectors: Small space, high-density, high frequency of

The development of the connector should be smaller, high-density, high-speed, high-frequency direction. Miniaturization is the central connector spacing smaller, high-density core to achieve a large number of. High density pcb (printed circuit board) connectors effective way to reach a total of 600 core items, special devices up to 5000 cores. High-speed transmission is the modern computer, information technology and network technology required time scale of signal transmission rate up to MHz frequency, pulse time to reach sub-millisecond, thus requiring a high-speed connectors. To meet the high-frequency millimeter-wave technology is the development of RF coaxial connectors have access to millimeter wave frequency band.

Switch should be small, thin, lightweight, surface mount, energy saving, high reliability, multi-functional, composite direction, and improve heat resistance, sealing, touch and environmental resistance.

Capacitors and resistors

Capacitors and resistors

Capacitors and resistors: chip-based, high-capacity, long life

Ceramic capacitor capacitor in the world market will remain dominant, small size, large capacity, high voltage, high frequency interference and the array of ceramic capacitors will be the development direction, while the products will be ceramic chip capacitors and tantalum capacitors mainstream.

Small size, large capacity, long life, high temperature, low equivalent series resistance (ESR) and other aluminum electrolytic capacitor is still the direction of development. Chip tantalum capacitor products continue to lead to smaller, high-capacity, low impedance, low equivalent series resistance direction, functional polymer tantalum capacitor production and application will be further expanded, tantalum powder CV value will continue to increase. Metallized plastic film capacitors demand will grow for the information and communications equipment, plastic film capacitor market will continue to expand. High frequency, to meet safety standards, high temperature, small size, chip type plastic film capacitor will be the direction of development.

Chip resistor resistor will continue to be the mainstream product, its size will continue to shrink, 0603 type (0.6mm × 0.3mm), will go into large-scale application stage. High resistance, low resistance and high voltage chip resistors needs to expand, the film chip resistor production and application will be further expanded with 2, 4 with a combination of type 1005 chip resistors to debut. High-power, small size, high stability, high precision metal film resistors will continue the development direction, while it will reduce the current noise and increase the added value of digital technology to the development of a metal film resistors, new applications, the precision type, ultra-precision products can not replace the chip resistors, and therefore, it will still have a certain market space. Wirewound resistors to the security of (fire), high precision, small size, direction and low resistance is the note of a trend.
