[0050] Embodiments of the present invention will be described in detail below with reference to the drawings. Figure 1 to Figure 3 is a diagram showing an example of a vehicle equipped with the first embodiment of the power supply control apparatus for a vehicle according to the present invention.

[0051] exist figure 1 Among them, the vehicle 100 is equipped with: an electric motor 12 equipped as a driving source for rotating wheels 11; a high-voltage component 13 for operating with high-voltage DC power; a high-voltage battery (battery) 14 for using High voltage power (current) that can be supplied to and consumed by the electric motor 12 or the high voltage part 13 for charging; and a controller 15 for controlling the electric motor 12 and the high voltage part by unified 13 of the various vehicle components to enable the vehicle 100 to travel. The vehicle 100 is configured as a so-called eco-car (ie, an eco-car) capable of running using electric energy.

[0070] then, Figure 4 is a diagram showing an example of a vehicle equipped with the second embodiment of the power supply control apparatus for a vehicle according to the present invention. Here, since this embodiment is configured basically the same as the above-mentioned embodiment, it will be used with figure 1 The same structures and the same reference numerals are used to describe these main parts.

[0071] exist figure 1 , the controller 15 according to Figure 4 The flow chart shown is to execute the electrical insulation degradation countermeasure processing procedure (processing method).

[0072] In this electrical insulation degradation countermeasure process, first, it is confirmed that the detected electrical insulation resistance value Rn detected by the electrical insulation degradation sensor 25 is lower than the set electrical insulation resistance value Rt (step S11), and that the vehicle speed detector 16 detects The running speed Sn of the vehicle sp...

Abstract

A power supply control apparatus for use in a vehicle is provided for ensuring necessary running and workability when an electrical insulation degradation of a high-voltage part is detected. A vehicle 100 having a high-voltage battery 14 and an inverter 17 is provided with: an electrical insulation degradation sensor 25 for detecting an electrical insulation degradation of the high-voltage part,main relays 22 and 23 for cutting off the supply of the power to the high-voltage part,a vehicle speed detector 16 for detecting a running speed Sn of the vehicle,and a controller 15 for causing the main relays to cut off the supply of the power as a power supply cutoff condition, when the electrical insulation degradation sensor detects the electrical insulation degradation of the high-voltage part and the running speed of the vehicle detected by the vehicle speed detector is lower than a preset speed St.

Description

technical field [0001] The present invention relates to a power supply control device used in a vehicle, and more particularly to a power supply control device for cutting off power supply in time when deterioration of electrical insulation of a high-voltage component is detected. Background technique [0002] Typically, vehicles are equipped with batteries for supplying electrical energy to various electrical components. Among these assemblies there are several high voltage components. For example, a hybrid vehicle running with a combination of an electric motor and an internal combustion engine or an electric vehicle running only with an electric motor is equipped with not only high-voltage components that operate using high-voltage DC power from a high-voltage DC power High-voltage parts such as motors that operate by converting the power supply voltage from a high-voltage DC power supply to AC. Since a fuel cell powered vehicle also converts various fuels into electric...
