Performance Requirements Current Specs (as VDA) prescribe a 500h salt-spray test, more than doubling the previous requirements. ? brush commutation at its limits (and beyond!) 2. E-cars Water-cooled batteries require an substantially higher runtime (more than 15 Kh) ? only achievable by electronic commutation 3. Economy General demand for more efficient vehicles: BL about 20% more efficient than brush at typical working conditions ? fuel savings, car components downsizing 4. Environment ? Less CO2 emission, avoidance of carbon dust pollution ?
