On April 30, 2015, Hangzhou, Zhejiang Province issued the “Regulations on the Regulation and Control of the Total Passenger Cars in Hangzhouâ€, and joined the ranks of the cities that implemented the total regulation and index management of small passenger cars (commonly known as the Yaohao bidding). Anyone who wants to apply for Hangzhou local machine For motor train licenses, the control indicators must be obtained by means of lottery or bidding in order to be licensed. Among them, in November 2015, the number of license plates for Zhejiang A was over 450,000, and 84 people grabbed a license plate. The competition is fierce. However, there is a way to directly license the card without regulation and control, that is, the new energy vehicle (pure electric vehicle or hybrid vehicle) can be directly used without the bidding price. Then the question is coming. If you want to buy a new energy car, what problem do you care most about?
If you let me buy a pure electric car, the first question I must pay attention to is how much can the cruising range be after a full charge? If the cruising range is only 80 kilometers under full power, then there is a danger of hitting the street at any time in a city like Hangzhou. If the cruising range is 200 kilometers at full power, then it can basically meet the one-day trip in the city road. If the cruising range in full power can reach 500 kilometers, then it is close to the traditional car's battery life, you can run in a short distance, at least in Zhejiang Province, you don't have to worry too much. Secondly, I will pay attention to the charging problem. The charging problem needs to be considered at the same time as the battery life. If the battery life is only 80 kilometers, then it must be considered whether the charging is convenient and fast. If the battery life is 500 kilometers, then you can fully use the rest time to charge. Does not affect normal driving use. Of course, the charging time is fast, and whether the charging pile is perfect is also a charging problem that people are worried about. Of course, the price is also an important issue that people care about. If the price of electric vehicles is high, it will definitely make the electric vehicles unpopular.
Here we talk about the cruising range of electric vehicles. Before the cruising range, what is the energy of pure electric vehicles?
As shown in the above figure, simply look at the electric vehicle is to output electric energy from the battery. The controller controls the inverter and then drives the main motor to bring power to the car, so that the car can run normally. Otherwise, when the car is braked, the main motor can be used as power generation. The machine sends the energy back to the battery for energy recovery. It can be seen that the whole energy conduction is the conversion of electric energy. If the efficiency of this conversion process is very high, the cruising range of the car can be greatly improved, otherwise the cruising range will be greatly affected. How can I accurately match the efficiency of the actual test electric vehicle energy conversion?
Yes, you must use the power analyzer to test with the car. The traditional power analyzer needs external power supply, and the body is huge. It is not suitable for on-board testing, just like a desktop computer. At this time, you must have a portable product. , like a tablet instead of a desktop.
The above ZLG Zhiyuan Electronics PAmini Power Analyzer is the first portable power analyzer on the market. It is half the size of the traditional power analyzer. It can expand the power section of 4 test voltages and currents and 1 motor section to measure the torque speed. And comes with a battery, no external power supply. In the case of full board, the weight is also about 5Kg, which is convenient for take-away. And the 9-inch touch screen is equipped to make the whole test perfect, and more importantly, the test analysis function does not make any cuts.
