Embodiment Construction

[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0012] Such as figure 1 As shown, the power management device is a very important part of the electric vehicle system. It distributes the electric energy from the battery pack to the DC power supply (DC / DC chopper power supply), AC equipment (such as vehicle air conditioners, lighting equipment, etc.) and motor, and lead the charging current from the charger to the battery pack. In addition, the electric vehicle system also includes a BMS (Battery Management System) that monitors battery pack information, and an on-board control system that monitors motor information. The DC power supply provides 12V or 24V power for the BMS; mode communication connection.

[0013] Such as figure 2 It is a schematic diagram of the management protection control circuit of the power management device, and the management protection control circuit is composed of a main circu...

Abstract

The invention relates to a power management device for an electromobile, which re-designs the circuit and installation way to solve the problem that scattered installation is poor in reliability. High voltage parts are arranged together in a sealed box body and a socket connected with various external devices and a manual switch are reserved on the external wall of the box body so as to avoid problems caused by connection of scattered installation, and the universality and transportability of products are improved and the product is easy to maintain. The socket is provided with interlocking terminals and when the interlocking terminals are connected with the sockets of various external devices with interlocking terminals, the interlocking terminals are in short circuit from head to end to form an access. When the access is communicated with a control signal in a control circuit and common terminals of control signals of contactors, the contactors will be controlled by the control circuit. Provided that one pair of plug and socket gets loose, the interlocking loop will be cut off so that the contactor trips to protect the loop so as to improve the safety and reliability greatly.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a device for electric vehicle power distribution management. Background technique [0002] Vehicle-mounted electric power integrated management system is the integration of electrical control and protection devices of electric vehicles. It is responsible for the power distribution, control and protection of the entire vehicle, and ensures the safe use of various electrical equipment. Its quality directly affects the performance and safety of the vehicle. . Most of the electrical control components and protection devices of traditional automobiles are independently set up and installed separately, or the control components are installed in a small space under the instrument panel, and various electrical components and control circuits are covered under the instrument panel. The above installation methods There are disadvantages such as complex wiring, many faults, inconvenient in...
