Problems solved by technology

However, until now, EHC has not been easily used in hybrid electric vehicles because known power supply networks installed in hybrid electric vehicles typically provide a supply voltage of around 350V DC, while EHC requires voltages typically between 10V DC and 50V Power supply between DC, such as 12V DC or 48V DC

Abstract

Disclosed is a power supply network (1) for installation in a vehicle, wherein the power supply network (1) is arranged to provide a first supply voltage so as to power electrical loads electrically connected to the power supply network with the first supply voltage. The power supply network (1) is arranged to power an electric load (6) which is configured to be powered with a second supply voltage smaller than the first supply voltage. Furthermore, disclosed is a vehicle comprising such a power supply network (1) operationally connected to the vehicle. The power supply network allows a more environmental-friendly operation.

Description

technical field [0001] The invention relates to a power supply network for installation in a vehicle, wherein the power supply network is arranged to provide a first supply voltage so as to provide the first supply voltage to electrical loads electrically connected to the power supply network. [0002] The invention also relates to a hybrid vehicle comprising such an electrical supply network operatively connected to the vehicle. Background technique [0003] Regulations regarding internal combustion engines in vehicles are becoming more stringent. The exhaust gases provided by internal combustion engines must be purified as much as possible by passing through catalysts before entering the environment. Catalyst performance generally increases with increasing temperature. The temperature of the catalyst generally depends on the temperature of the internal combustion engine. Therefore, for some time after a cold start of the internal combustion engine, the catalyst may stil...
