In the four core systems of electric cars, the electric drive system is referred to as the “electric heart” of the vehicle, whose performance directly determines the motority, economy and comfort of the vehicle as a whole. As the market penetration of new energy vehicles continues to rise, the heart is facing unprecedented demanding demands: more efficient, smaller, more reliable, more wide-spreaded and lower-cost.
Challenge: A few of the power-driven systems.
Traditional electric power-driven programmes often face multiple challenges in responding to the complex and variable operation of modern electric vehicles:
- Responsive speed and efficiency bottlenecks: under the scenario of energy recovery for start-up, acceleration and brakes, conventional power plant switches are depleted and slow to respond, resulting in inefficient energy recovery
- Power density dilemma: a limited total vehicle space requires that electrical systems be small in size and of low quality, but produce greater power
- Reliability and intervention resistance challenges: complex electronic environment of vehicles, severe electromagnetic interference (EMI), high rate of vibration, high level of system reliability
- Severe working conditions: wide work voltage currents, high noise control requirements and increasing cost pressures
Breakout: Triple technological innovation in MOT Mos products
In the face of industry pains, the MOT electrons have built up with deep power semiconductor technology and launched a full-scale MOS product solution for the motor-driven market, with a triple breakthrough from chip design to containment:
