Definitions
- the invention relates to a method and a device for overvoltage protection in dual voltage electrical systems.
- Such two-voltage electrical systems are for example from the
- Automotive technology known. Due to the increasing number of electrical consumers, a single power supply is often no longer sufficient. Furthermore, electrical consumers are used which either require a higher operating voltage and / or higher electrical powers, so that
- Dual-voltage electrical systems have been developed which have a different voltage level of, for example, 14V and 42V. It is also known to connect these electrical systems via a DC / DC converter so that they can be supplied, for example, via a common generator.
- the basic problem of such dual-voltage electrical systems is that the electrical consumers in the vehicle electrical system with the low voltage level must be protected against static overvoltages due to a short circuit between the two vehicle electrical systems. This can be done, for example, by designing the electrical consumers in the vehicle electrical system with the low voltage level with corresponding overvoltage protection elements that are designed for the voltage in the other vehicle electrical system.
- a disadvantage of this procedure is that all electrical consumers that have previously been used in vehicle electrical systems with a low voltage level would have to be modified.
- the invention is therefore based on the technical problem of creating a device and a method by means of which the electrical consumers in the vehicle electrical system with the lower voltage level are more easily protected against overvoltages due to the other vehicle electrical system.
- the solution to the technical problem results from the subjects with the features of claims 1 and 8. Further advantageous refinements of the invention result from the subclaims.
- a switching element is arranged in at least one branch of the vehicle electrical system at the higher voltage level and a voltage measuring unit is arranged in the vehicle electrical system at the lower voltage level, which can switch off voltage branches in the vehicle electrical system with the higher voltage level when an overvoltage is detected via the circuit element (s) and thus the cause of can eliminate the surge.
- the switching elements can either be arranged in all safety-uncritical branches or only in the branches where there is a serious risk of short-circuits with the other vehicle electrical system due to the wiring.
- the voltage measuring unit can be connected to the switching elements either via control lines or a CAN bus or other bus systems.
- On-board networks are galvanically connected to one another via a DC / DC converter, the voltage measuring unit is preferably integrated into the DC / DC converter.
- the switching elements are preferably designed as semiconductor switching elements, in particular as MOSFETs.
- the voltage in the vehicle electrical system is measured with the lower voltage level and when an overvoltage is detected, branches in the vehicle electrical system with the higher one are switched
- the voltage is switched off successively until there is no more overvoltage.
- branches that have to be protected separately such as the left and right side of the
- Vehicle lights are switched off one after the other, with one branch being switched on again before the other is switched off, so that one branch remains ready for operation. This is because the overvoltage occurs after the first branch has been switched off
- the invention is based on a preferred
- the single figure shows a schematic circuit diagram of a two-voltage electrical system with surge protection.
- the dual-voltage electrical system 1 comprises a first voltage source U1 and a second voltage source U2, U2> U1.
- a DC / DC converter 2 is arranged between the two voltage sources U1, U2, via which the on-board networks can be connected in spite of the different voltage levels.
- First electrical consumers R4 are arranged in the first electrical system with voltage source U1 and second electrical consumers R1-R3 are arranged in different branches in the second electrical system with voltage source U2.
- a switching element S1 or S2 is arranged in each of the branches of the electrical consumers R1 and R2.
- a voltage measuring unit 3 which measures the voltage in the first electrical system, is arranged in the first electrical system.
- Voltage measuring unit 3 is connected to the control inputs of the switching elements S1 and S2.
- the electrical consumers R3, in the branch of which no switching elements are arranged, are, for example, safety-critical consumers, such as an electrical steering system or an electrical brake, which must not be switched off. Furthermore, no switching elements have to be arranged in branches that are far away from the first electrical system due to their arrangement.
- the voltage measuring unit 3 continuously measures the voltage in the first electrical system. If, for example, there is a short circuit between the branch of consumer R1 and that of consumer R4, the sensor detects
- Voltage measuring unit 3 the overvoltage in the first electrical system.
- the voltage measuring unit 3 switches the first switching element S1 so that it opens or blocks and switches off the branch of R1. In the example shown, the cause of the overvoltage has thus been eliminated.
