Introduction

42 Volt Systems are rapidly emerging as the technical solution for improved emissions, fuel consumption and higher electrical power requirements. These higher power requirements can not be cost effectively or technically supplied by a 12V system.

 

Assuming a 6 to 8kW power requirement, it now becomes practical to combine the starter and alternator into a single starter-generator unit. This combination with the peak overload torque provides the capability for mini-hybrid (not to be confused with the full hybrids) start / stop operation at zero or little extra cost. Small engine performance, critical to 42 Volt adoption, is thus enhanced along with emissions and fuel consumption.

 

42 Volts will reduce the cost of some existing systems including: coil on plug, many solenoid operated devices, motor drive circuits, large power connectors, etc. But it will also lead to cost increases on certain types of devices such as relays, mechanical power switches, coil winding, motor components, etc.

 

42 Volts and its resulting higher power will be the enabler for a range of new technologies and the change agent for many others. Typical applications will include electric power steering, water pumps and door closures, advanced braking and suspension systems, hermetically sealed air conditioning, and further displacement of viscous fan drives.

The 42-volt System

This TIER ONE study reports on the developing market, its relevant technologies and their implementation in the forthcoming transition to 42-volt electrical systems.

Opportunity

The study profiles and provides a comprehensive assessment of emerging market opportunities for 42-Volt Electrical Systems. The transition to 42V will span this decade and provide extraordinary growth and product opportunities for electronics companies. It may also adversely affects companies who manufacture many of the electromechanical components now used in high volume applications. High current switch's and relays are obvious candidates for change. There are other technology challenges for devices such as brush less electric motors, while not cost effective today, could be beneficial in future automotive applications.

The report covers North America, Japan, and Europe.

Why 42 Volts?

Driving forces vary by geographic market, but the major factors include:

- Mandated fuel economy standards
- Mandated emissions standards
- Higher electrical loads from convenience     features
Europe Will Lead

BMW, Mercedes, PSA (Citroen & Peugeot), Renault and Fiat already have plans for 42-volt systems in vehicles by 2002/2003. They are introducing the 42-volt system as part of emissions management, a prime concern in Europe.

Standards

Currently there is no global standard architecture for the 42-volt system. However the German Industry have established one by default. The French and Italians seem likely to follow.

Electrical Demand

Vehicle electrical demand has doubled over the last 20 years. 12 Volt electrical systems at the current power level have seen little, other than evolutionary, change on a system where cost has almost always been the primary design criteria. Today, 12 Volt systems are taxed to meet the power demand and further, due to its inefficiency, negatively affects fuel consumption. New electrical systems (42 Volts) with much higher operating efficiency are essential to meet forthcoming demand. Moreover, the new architecture spawns other electrical applications that yield even bigger emission and fuel consumption advantages.

Safety

42 Volt systems meet government regulations for safety while higher Voltages do not. It is generally agreed that d.c. Voltage at around 60 V peak is unlikely to generate a major safety hazard hence special protection beyond existing materials should not be required. While making the systems safe under fault conditions is more involved, these requirements will further generate new business opportunities.

Requirements

42 Volts specifications have stricter requirements. The most important restriction is an absolute maximum transient of around 60 V. Based upon operating current this makes the cost of the enabling FET technology very affordable and easily within existing semiconductor production processes. To enable this power conditioning transient, protection is centralized at the source. For example, maximum negative voltage is -2Volts for 0.1 second compared to -12 Volts for the old system.

  Concurrently, battery and battery terminal protection is essential to ensure that reverse voltage cannot be applied. A new and protected port for jump-starts and battery terminal access must be defined.
