ترجمه چکیده
Introductory, the BMW micro-hybrid functions BER and ASSF were described. The emerging challenges for the battery were discussed by means of first field experience. The field data, acquired by the method of after sales analysis, revealed higher cycling rates and lowered SOC distribution on average. Under those conditions and due to the fact that maximum charge acceptance is required for regenerative braking, VRLA batteries in AGM technology promise best performance on request of package and price. Since battery behavior with a PSOC operation strategy in high-volume series applications is widely unknown, we designed a long-term lab investigation under preferably realistic and controllable conditions. We conclude that AGM batteries of both measured types are suitable for the use at least in mid-sized Micro-HEVs. Especially, we demonstrated that periodically recharging of the battery improves charge acceptance significantly. This battery refresh prevents Pb sulfate crystals to grow irreversibly especially in the negative plate as intensely discussed in literature. The maximum capacity loss would account for 30% after 90 full cycles (i.e. about 60,000 km mileage or 4 years) at an average temperature of 25 °C. Note, that the C20 measurement plus recharging recovers the battery to some extent as well. The stage of development of the tested batteries was at the beginning of the year 2006.

چکیده انگلیسی

The BMW Group has launched two micro-hybrid functions in high volume models in order to contribute to reduction of fuel consumption in modern passenger cars. Both the brake energy regeneration (BER) and the auto-start-stop function (ASSF) are based on the conventional 14 V vehicle electrical system and current series components with only little modifications. An intelligent control algorithm of the alternator enables recuperative charging in braking and coasting phases, known as BER. By switching off the internal combustion engine at a vehicle standstill the idling fuel consumption is effectively reduced by ASSF. By reason of economy and package a lead–acid battery is used as electrochemical energy storage device. The BMW Group assembles valve-regulated lead–acid (VRLA) batteries in absorbent glass mat (AGM) technology in the micro-hybrid electrical power system since special challenges arise for the batteries. By field data analysis a lower average state-of-charge (SOC) due to partial state-of-charge (PSOC) operation and a higher cycling rate due to BER and ASSF are confirmed in this article.

نتیجه گیری انگلیسی

Within the BMW EfficientDynamics initiative several activities are focused on the reduction of fuel consumption and CO2 emissions of modern passenger cars. Those developments are based on increased efficiency of the internal combustion engines (ICE), a consequent lightweight construction strategy and sophisticated aerodynamic features of the car body. By an intelligent energy management the vehicle electrical power system also contributes to the EfficientDynamics program resulting in an upgrade of the conventional power supply to the micro-hybrid electrical power system. The BMW short-term strategic approach is to implement micro-hybrid functionality in almost the whole product portfolio in order to reduce the average CO2 emissions of the BMW vehicle fleet according to the ACEA (European Automobile Manufacturers’ Association) voluntary agreement in 1998. In a further mid-term oriented step higher levels of powertrain hybridization are developed and implemented in mild and full-hybrid vehicles.
