(孟子)说:“没有关系,这是体现了仁爱之道,(原因在于您)看到了牛而没看到羊。有道德的人对于飞禽走兽:看见它活着,便不忍心看它死;听到它(哀鸣)的声音,便不忍心吃它的肉。因此君子不接近厨房。” 齐宣王高兴了,说:“《诗经》

英文:Great progress has been made in batteries in recent years. However, the time has come for achange in emphasis. Previously the pure battery electric was seen as the desired solution. Even ifthe remaining technical issues can be addressed, we are still impeded by weight and cost of sucha solution. Consequently Polaron believe they should focus on hybrid solutions and this needsbatteries optimized for peak power not energy capacity. It requires batteries with geometriesoptimized for peak power – ultra-low internal resistance and perhaps high capacitance at the sametime. It will certainly require new packaging. A capacity of 2 kWh at 2 minute rate would beadequate for the average family car. It will also require a low cost short-circuit device to bypasshigh resistance cells in long series strings.There is now little doubt that brushless DC machines offer the best overall performance whenused in vector control mode, with high voltage windings, Fig. 3.6. The reason is that the brushlessDC motor offers the lowest winding current for the overall envelope of operation. An electricvehicle has to provide a non-linear torque/speed curve with constant power operation from basespeed to maximum speed. In a brushless DC motor, the motor voltage may be held constantover this range using vector control. In an induction motor, the motor voltage must rise over theconstant power speed range. If V and I are the voltage and current at maximum speed and powerthe values at base speed are V ´ (Base Speed/Max Speed)1/2, I ´ (Max Speed/Base Speed)1/2. Ifmaximum speed / base speed = 3.5 times, the current at base speed is 1.87I. Consequently theinduction motor inverter requires 1.87 times the current capacity of the brushless DC motorinverter.The most significant improvement recently for brushless DC machines has been thedevelopment of the Daido magnet tube in Magnaquench material. This product offers the benefitsof high energy magnet and containment tube. This leads to a third benefit which is not immediatelyobvious but very significant. Surface magnet motors usually employ a containment sleeve whichadds several millimetres of air gap to the magnetic circuit. Since magnet tube does not requirea sleeve if used within its speed capability, a thinner magnet tube is possible whilst maintaining
