On April 8-10, 2016, Shenzhen Convention and Exhibition Center ushered in the 87th China Electronics Show. Under the hot situation of the new energy industry, exhibitors have exhibited relevant solutions. At the Aidex booth, the reporter saw professional charging pile / charger test program, battery charge and discharge test program, photovoltaic grid-connected inverter test program.
Advanced charging pile / charger test solution
The electrical and thermal performance test scheme of the ACCOM's charger is in accordance with GBT18487.1 Electric Vehicle Conductive Charging System Part 1 General Requirements 2015; GBT20234.1 Electric Vehicle Conductive Charging Connection Device 2015; GBT27930 Electric Vehicle Non-vehicle Conductive Communication protocol between the charger and the battery management system 2015. Moreover, the Idex charging pile/charger test system can simulate the vehicle control system, control and monitor the fault status and operating parameters of the charger, and simultaneously monitor the test system and the DUT itself through a set of test software to make the operation flow more concise and clear. . When referring to the current compatibility issue between charging pile/charger testing, Idex product manager Ms. Judy Zhu told reporters that when the charger is connected to AC, it does not immediately output power to the battery. The BMS battery management system first collects and analyzes the state of the battery, and then adjusts the charging parameters of the charger. However, many BMSs on the market are designed and manufactured only for batteries of a certain type or even a certain type of vehicle. Actually, it is ideal for specific battery effects, but when applied to batteries of other models or brands, it loses its proper function, so charging The design and development of the machine is also specific to the model or BMS type. This means that manufacturers of chargers will have test requirements for chargers with different charging protocols. Therefore, the charging pile/charger test system developed by Idex can realize the control and monitoring of the charger under the condition that the charger manufacturer does not provide the protocol, and automatically analyze the message during the operation to obtain Charger operation and fault parameters. This also represents the current advanced technology and future trends in charging pile/charger testing.
Automotive brake backlash test program and automotive electronic test solution
When the electric vehicle is taxiing, in order to achieve the same effect as the conventional vehicle brakes, a certain sliding speed reduction reference curve is observed, and the V/I curve of the power battery output is required. Idx's new IT6500C wide-range high-power DC power supply can simulate and output the brake backlash curve in the laboratory due to its ultra-fast dynamic response time (<50us) and the function of absorbing current and voltage with the power dissipator. Perform a brake backlash test on the power battery.
The power supply also incorporates test curves specified by the DIN40839 and ISO16750-2 standards, allowing engineers to directly test for engine start, voltage transients and reset performance.
A variety of products for the audience to choose
At the IDK booth, you can see the new products including the upcoming IT7626 high-performance AC power supply, IT5102 internal resistance tester, etc. The IT6500 wide-range high-power DC power supply (800W~30KW) and IT8615 are specially paid attention by engineers. DC electronic load, IT6412 dual-channel bipolar DC power supply (battery simulator), etc., also has a series of classic products that engineers are most familiar with. IT8800 high-speed and high-precision DC electronic load, IT8700 multi-input DC electronic load, IT6300 three-channel DC power supply, IT7300 AC power supply, IT9121 power meter, etc. New and old products are unveiled, new products are revitalized, old products are expanding, and any audience with different needs can find suitable products at the Ixex booth.
The atmosphere is lively and the event is rich.
The audience learned about the products at the booth, and many media also came to the Idx booth to report the interviews, and the crowds were full of people. At the booth, Ixex also held a “Photo Wall Collection†event, paying attention to the “Idex Electronics†WeChat public number, and taking a photo with the Eckers booth, the photo will be selected for the election. Photo wall, but also draw prizes to win benefits.
Next, Idx's marketing activities will also enter Beijing, Xi'an, Shanghai, Hangzhou, Chengdu, Chongqing, Xiamen and other cities, the reporter will conduct more reports.
Take a deep breath, close your eyes, the world has the freshest oxygen ... Yu Quan's "Deep Breath" is well known to us, but as the environmental problems become more and more serious, the haze sky also increases, PM2.5 PM10 and so on Vocabulary has also been mentioned more and more, and air purifiers have quickly become popular on the market with this "air quality" trend. Along with this, the air-clean brand has sprung up, and various technologies are dazzling. Which ones are indeed effective and which are just tasteless propaganda? How does the Air Purifier bother us to get rid of pollution? And look at the editors for you.
Analysis of air purifier
The critical value of PM2.5 content is 75 μg / m3
The pollutants in the air mainly include soot, total suspended particulates, inhalable particulates (PM2.5) and fine particulates (PM10). The smaller the diameter of the particulates, the deeper the part that can enter the respiratory tract. 10 micron diameter particles It is deposited in the upper respiratory tract, and particles below 2 microns can penetrate 100% into the bronchiole and alveoli.
1k-5k air purifier prices vary greatly
The air purifier products on the market not only have various functions, but also have prices ranging from thousand yuan to tens of thousands. The pricing of imported products is generally higher than that of domestic brands. Except for the core technology of many brands, the promotion of purification effects is similar, and consumers need to choose according to demand.
The air quality standard of 74 key cities is only 4.1%
According to the data of the press conference held by the State Council Information Office on June 4, according to the new "Ambient Air Quality Standards", the six pollutants SO2, NO2, PM10, PM2.5, CO and O3 were evaluated, 74 new standards In the first phase of monitoring and implementation, the proportion of cities that met the ambient air quality standards was only 4.1%, and the other 256 cities implemented the old air quality standards, and the proportion of cities that met the standards was 69.5%.
Air purifier sales increased by 90.5% compared with last year
According to a report recently released by the China Electronics and Information Industry Development Institute, due to the haze weather, air purifiers have become the most concerned home appliance products, with sales of nearly 2.4 million units nationwide last year, a year-on-year increase of 90.5%; retail The amount reached 5.6 billion yuan, a year-on-year increase of 105.9%.
HEPA filter needs to be replaced in March
The filter of the air purifier is the same as the filter of the water purifier, and it is not effective for a long time. After long-term use, the accumulation of dust on the surface of the filter will also cause the filter to gradually fail. Therefore, when the haze is more serious, the non-washable HEPA filter needs to be replaced every three months.
Merchants claim that the purification rate is more than 99% for the concept of stealing
99% or even 99.99% seems to have become a slogan for many air purifiers on the market. Many brands of products promote their high removal rate of PM2.5 and formaldehyde. In fact, this kind of publicity is more of a kind. The slogan of stealing the concept, the removal rate of 99% is the effect of the material itself on PM2.5 and formaldehyde, not the effect of actually running in space.
