To master the challenge of reduced emissions and improved energy efficiency, Infineon provides innovative solutions that leverage best-in-class technologies and system know-how. Our electrification solutions take energy management to the next level.
The following provides an overview of the most relevant areas in vehicles to improve energy efficiency. By clicking the respective links you’ll be forwarded to exemplary block diagrams and detailed product information.
(Hybrid) Electric Vehicle
(Hybrid) Electric Vehicles represent one of the most efficient energy conversion approaches for personal transportation. Due to our system expertise we are able to provide complete chipsets offering the best balance between performance and cost.
Electric Water pump
The main benefits of an EC-motor driven water pump are improved thermal engine control and a better pump efficiency. Infineon offers the complete product portfolio to address both high performance and low cost systems. Electric Water pump
Fuel pump
A PWM controlled fuel pump means “Power on Demand”. It runs only at full speed when needed which enables a power consumption reduction by 40% in average. Fuel pump
Alternator
A replacement of diodes by B6-MOSFET-bridge enables an efficiency improvement of 10% by means of reduced diode losses (calculated with 1.0 kW). Alternator
Battery Management
Adequate battery management enhances both safe operation and lifetime extension. Battery Management
HVAC
Balancing comfort and energy efficiency is very important in automotive air conditioning. Reduced energy consumption can be achieved by demand-oriented climate regulation. This could be covered by, for example, fresh air regulation (recirculating air operation) or the usage of brushless DC motors in fans. HVAC
EPS
EPS A PWM controlled (EC-motor with filed oriented control) Electric Power Steering provides torque only when needed. This could lead to a power consumption reduction from 300W to less then 50W in average. Infineon offers the complete product portfolio to realize such systems. EPS
Tire Pressure Monitoring System
Tire pressure is also contributing to poor fuel economy. Twenty-three percent of vehicles have at least one tire that is under inflated by at least 20% or 8 pounds per square inch. This could mean reduced fuel economy by 4%. By maintaining proper tire pressure, tire lifetime as well as vehicle fuel economy can be increased. TPMS
