Abstract

The invention provides an inverter controller assembly with high-low-voltage dual-power-source input and a control method. The inverter controller assembly comprises a high-voltage power battery, an inverter power supply, an oil pump motor and a backup battery. The high-voltage power battery is electrically connected with the inverter power supply, and a relay is arranged between the high-voltagepower battery and the inverter power supply. The inverter power supply is electrically connected with the oil pump motor. The backup battery is electrically connected with the inverter power supply. By the adoption of the above technical scheme, the backup battery is additionally arranged in traditional DC/AC, so that under the circumstance that the high-voltage power battery is abnormal, power supplying of the oil pump motor is normal continuously, and the situation that the automobile steering assisting force is lost, and then hidden safety hazards are caused is avoided. The provided schemeis simple and reasonable, the assembly can be suitable for an existing full electric vehicle or a hybrid electric vehicle, user-friendly design is relatively high, and the assembly meets the demand ofdevelopment of the current full electric vehicle or the hybrid electric vehicle.

Description

technical field [0001] The invention belongs to the technical field of automobile power supplies, and in particular relates to an inverter controller assembly and a control method with high and low voltage dual power supply inputs. Background technique [0002] DC / AC (inverter power supply), widely used in various pure electric and hybrid vehicles; such as figure 1 As shown, the traditional DC / AC is used to provide power to the oil pump motor of the vehicle steering power. When the power battery fails or there is a safety hazard, the output of the battery may be disconnected. At this time, the DC / AC that provides power to the oil pump motor It will also lose power due to the disconnection of the power battery. At this time, the power steering is lost. For large buses, it is quite dangerous, which is equivalent to losing control of the direction. [0003] Based on the above-mentioned technical problems in the electric vehicle power input, there is no relevant solution; there...
