Problems solved by technology

[0004] After the high-voltage battery pack fails, although the battery pack control module can cut off the fault circuit from the high-voltage power distribution box, it cannot handle the faulty high-voltage battery pack. There is still a risk of leakage, fire, or even explosion in the event of a fault
Especially for multi-axle special off-road electric vehicles that are used in special environments (poor road environment, impact conditions), the faulty high-voltage battery pack will seriously threaten driving safety in the vibration and impact driving environment

Embodiment 1

[0036] An embodiment of the present invention provides a vehicle-mounted high-voltage battery pack automatic shedding device, see Figure 1 to Figure 3 , including an outer shell, a shedding seat 30, a drive assembly and a camshaft 60. The outer casing is used to connect with the steel structure of the vehicle body, and the end of the outer casing is provided with an interconnected installation groove 11 and a positioning semicircular groove 12; the dropout seat 30 is used to connect the high-voltage battery pack, and the dropout seat 30 has The mounting portion 31 in the groove 11 is provided with a disengagement semicircle groove 32 on the mounting portion 31. When the mounting portion 31 stretches into the mounting groove 11, the disengagement semicircle groove 32 is opposite to the opening of the positioning semicircle groove 12 and spliced ​​into a circular groove 100 The drive assembly and the camshaft 60 are installed inside the outer shell, the drive assembly is used t...

Embodiment 2

[0055] Based on the same inventive concept, this embodiment provides an electric vehicle, which can be any existing large-scale multi-axis electric vehicle that adopts a high-voltage system and a distributed power supply scheme. The driving status of the car is equipped with a display control terminal on the dashboard of the cab. The driver can obtain key data during the driving process of the vehicle through the display control terminal, and can also perform manual operations, such as controlling the door switch and adjusting the temperature of the air conditioner. The energy storage system adopts a distributed power supply scheme, which is composed of multiple distributed power battery packs (ie, high-voltage battery packs), and is connected to the corresponding high-voltage power distribution box, and the power management controller in the high-voltage power distribution box realizes energy management and monitoring.

Abstract

The invention discloses a vehicle-mounted high-voltage battery pack automatic shedding device and an electric vehicle. The vehicle-mounted high-voltage battery pack automatic shedding device includes an outer shell, a shedding seat, a driving assembly and a camshaft. The outer shell is used for connecting with the steel structure of the vehicle body. The end of the outer casing is provided with a mounting groove and a positioning semicircular groove; the dropout seat is used to connect the high-voltage battery pack, and the dropout seat has a mounting part that can extend into the mounting groove, and the mounting part is provided with a release semicircle groove, when the mounting part extends When inserting into the installation groove, disengage the semicircular groove and face the opening of the positioning semicircular groove, and splice into a circular groove; the driving assembly is used to drive the camshaft to rotate; the camshaft includes a shaft part and a cam part, and the shaft part of the camshaft is connected with the driving assembly. The cam portion of the camshaft protrudes from the outer shell and can rotate in the circular groove. The present invention uses the above-mentioned detachment device to install the high-voltage battery pack on the vehicle, and controls it to automatically detach from the vehicle when the faulty battery pack is identified and located by the system, so as to realize the active safety function.

Description

technical field [0001] The application belongs to the technical field of vehicle mounting devices, and in particular relates to a vehicle-mounted high-voltage battery pack automatic shedding device and an electric vehicle. Background technique [0002] The energy storage system for large multi-axis electric vehicles adopts a high-voltage (such as 600V) system and a distributed power supply scheme. The power management controller in the high-voltage power distribution box realizes energy management and monitoring. [0003] At present, each battery pack control module of the electric vehicle power management controller has the functions of real-time monitoring and detection (such as insulation detection, thermal runaway and combustion alarm, etc.) of the power battery pack, and can quickly identify and locate the faulty battery pack when a fault occurs , When necessary, the fault circuit can be automatically cut off for safety protection. [0004] After the high-voltage batt...
