Summary:

The traditional twelve-volt automotive system is already being strained by luxury add-ins and with the coming inclusion of the next generation powertrain systems, it is now apparent that the electrical system has to provide more power than a twelve-volt system could ever economically supply. The advances in HCCI and SI engine technology will lead to direct injection, Variable Valve Actuation and Control, variable compression technology and CVT transmissions that require much more electrical energy than the current alternator can supply.The hybrid vehicle and the drive towards fuel cell vehicles will enable a series of other exciting options to the automotive digital design engineer. The enablement of new hybrid powertrain solutions, x-by wire, Digital Electro-Mechanical Brake (EMB) and electric power assisted steering systems that a 42 volt electrical system becomes a clear next generation choice for many automotive OEM's. The electrical systems that are enabled by hybrid powertrain vehicles brings new system partitioning options along with new challenges
