Current status and penetration rate of the start-stop market
Auto engine start-stop technology is also called "Auto-Stop, I-Stop", which was first developed by Honda as early as the 1970s. However, it was configured in 2006 thanks to the increasingly stringent environmental regulations of the European Union, and it has gradually become the standard for high-priced models in the market.
With the development and maturity of micro-hybrid vehicle technology, OEMs are actively developing vehicles with start-stop systems. In 2018, my country will fully popularize the national 5 emission standards, and in the first-tier cities of Beijing, Shanghai and Guangzhou, the national 5 has already been implemented. In terms of nitrogen oxides for gasoline vehicles alone, the national 5 emission limit is 25% stricter than the national 4 emission limit, and the sulfur content limit has dropped by 80%. This poses no small challenge for car companies. In the country 5 city standard test conditions, the vehicle idling time reached 31%. In the face of increasingly congested urban traffic, the automatic start-stop function is currently the best way for car companies to respond to regulatory requirements.
The main body of the AGM battery used in the start-stop system is a lead battery. The start-stop system mainly includes an enhanced starter with AGM battery, SISS direct injection ignition starter engine, BSG generator-starter integrated machine and ISG integrated motor/generator.
The most basic and widely used start-stop system-AGM battery + enhanced motor. This kind of start-stop system becomes the Idle-stop idling stop system, the main use of enhanced starter and AGM battery (enhanced battery) to start the engine. Since this method is not much different from the ordinary starting vehicle method, the battery and the starter need to withstand greater pressure, and more sensors and controllers are required to detect and control. In this way, the most important thing is to strengthen the starter and battery.
Most of this kind of start-stop system adopts separate combination of starter, that is, every time the starter gear is started, it needs to be combined with the flywheel to increase the working pressure of the starter, so that when starting, you must wait for the engine speed to drop to zero (partial start-stop system starter With the often combined type, the engine speed does not need to drop to zero, and the engine can be started at any speed). Therefore, the starter needs to strengthen its durability. The use of permanent magnet types, strengthened shift forks, increased number and size of brushes, and strengthened gears enable the starter to undergo high-intensity work. Therefore, the starter of the vehicle equipped with this kind of start-stop system is more durable than the traditional starter, and the service life can reach 300,000 times.
In addition, the battery also needs to be specially strengthened so that it can be quickly charged and discharged, and it also needs to have a high capacity to cope with the working use of the electrical appliances in the car with the engine stopped. Ordinary lead-acid batteries cannot be discharged with large currents many times during the interruption time, and their separators cannot allow rapid passage of electric ions. Therefore, a car with a start-stop function needs a larger capacity battery.
AGM technology (adsorption glass fiber cotton separator) and EFB technology (enhanced water injection battery) can greatly increase the rated capacity of battery storage.
Vehicles with start-stop systems mainly use lead-acid batteries with AGM ultra-fine glass fiber separators. This kind of AGM lead-acid battery has high acid resistance and stronger absorption of electrolyte, so as to achieve a smaller internal resistance and prolong the life of lead-acid accumulating batteries; the most important thing is that its deep discharge performance is good, allowing frequent high current discharge in a short time. .
The start-stop system has been widely popularized in Europe, America and Japan. As the largest automobile market in my country, the assembly rate of the start-stop system is very low. The market penetration rate has shown rapid growth in the past two years. The current market penetration rate is about 17%. , And this data was less than 10% in 2014.
