Description

Vehicle battery system protection device {PROTECTION APPARATUS FOR BATTERY SYSTEM OF VEHICLE}

The present invention relates to a battery system protection device for a vehicle, and more particularly, to a technology for protecting a battery system mounted to supply power of a so-called environmental vehicle such as HEV, PHEV, EV, FCEV, etc. from external shocks. .

Vehicles such as a hybrid electric vehicle (HEV), a plug-in hybrid electric vehicle (PHEV), an electric vehicle (EV), and a fuel cell electric vehicle (FCEV) are basically equipped with a battery system for driving an electric motor. .

For reference, the FCEV is equipped with a fuel cell different from a conventional battery, but the term "battery system" is used herein as a concept including all devices that supply electricity by a chemical method such as the fuel cell. .

Since the battery system as described above is relatively large in size and weight and heavy, there are many obstacles in selecting a vehicle's mounting position. Therefore, when the battery system is installed in a conventional trunk room, there is a problem such as greatly reducing the utilization of the trunk space. In case of mounting in the place where was installed, the safety problem in the rear collision acts as a big obstacle.

Conventionally, when the battery system is mounted near and at the spare tire mounting position in the lower part of the luggage compartment, there is a safety problem in the rear collision as described above, but the utilization of the luggage compartment space is considerably increased and it helps to balance the front and rear weight of the vehicle body. In such a preferred aspect, solving the safety problem in the rear collision has emerged as a major technical problem.

The matters described as the background of the above-described invention are merely for the purpose of improving the understanding of the background of the present invention, and are accepted as acknowledging that they correspond to the prior art already known to those skilled in the art. I will not.

KR 1997-0069643 A

The present invention has been made to solve the above problems, when the battery system is installed in the rear of the vehicle near the position where the conventional spare tire was mounted, by preventing damage to the battery system against the rear collision of the vehicle Its purpose is to provide a vehicle battery system protection device to greatly improve the safety of the battery system and to comply with various safety regulations.

Battery system protection apparatus of the present invention for achieving the object as described above

A battery system disposed at the rear of the vehicle;

An airbag module installed at a rear of the vehicle than the battery system and configured to buffer a rear collision of the vehicle;

A collision detection sensor installed in the vehicle body to detect a rear collision of the vehicle;

An airbag controller configured to control the driving of the airbag module by receiving the signal of the collision detection sensor;

And a control unit.

According to the present invention, when the battery system is installed at the position where the spare tire is conventionally installed and near the rear of the vehicle, the battery system is prevented from being damaged against the rear collision of the vehicle, thereby greatly improving the safety of the battery system and providing various safety. Ensure compliance with laws

1 is a view showing an embodiment of a battery system protection device of a vehicle according to the present invention,
2 is a view showing a battery system protection device for a vehicle according to the present invention, viewed from the rear upper side of the vehicle,
3 is a detailed view of the main part of FIG.
4 is a flowchart illustrating the operation of the present invention.

1 to 3, the battery system protection device of the vehicle of the present invention includes a battery system (1) disposed at the rear of the vehicle; An airbag module (3) installed at the rear of the vehicle than the battery system (1) and installed to cushion the rear collision of the vehicle; A collision detection sensor 5 installed in the vehicle body so as to detect a rear collision of the vehicle; It is configured to include an airbag controller (7) provided to receive the signal of the collision detection sensor 5 to control the driving of the airbag module (3).

That is, the airbag module 3 is provided to protect the battery system 1 installed at the rear of the vehicle from impact force such as a rear collision accident.

The battery system 1 is installed below the rear trunk room of the vehicle, and the airbag module 3 is installed on the back panel 9 of the vehicle body. That is, in the present embodiment, the battery system 1 is mounted by utilizing a spare tire mounting space and a space in the vicinity of the conventional luggage compartment lower side, and thus the battery system 1 installed close to the rear side of the vehicle body. In order to protect against external impact force that may be applied from the rear side, the airbag module 3 is mounted on the back panel 9 which is a rear end side panel of the vehicle body.

Of course, a buffer space 11 is provided between the rear side of the battery system 1 and the back panel 9 to expand and cushion the air bag cushion of the air bag module 3, and the air bag module 3 is It is a structure installed on the front side of the back panel 9 to expand the air bag cushion to the buffer space (11).

On the other hand, it is preferable that the collision detection sensor 5 is installed on the rear side of the vehicle body as compared to the air bag module 3 so as to be able to detect whether the rear collision of the vehicle and the degree of impact force even a little earlier. The collision detection sensor 5 is configured to send a signal to the airbag controller 7 that operation of the airbag module 3 is necessary only when the detected impact force exceeds a predetermined reference value.

Therefore, the airbag controller 7 receives a signal from the collision detection sensor 5 only when a shock force equal to or greater than a reference value is detected by the collision detection sensor 5 as shown in FIG. 4. To drive the airbag cushion.

On the other hand, the present embodiment further comprises a power cut-off means for blocking the drawing of power to the outside from the battery system 1 when the airbag module 3 is driven in response to the signal of the collision detection sensor (5). .

That is, the power cutoff means receives a signal from the collision detection sensor 5 through the airbag controller 7 and transmits a power cutoff command of the battery system 1 (HCU: Hybrid Control). Unit: 13, a battery management system (BMS: 15) that manages the battery system 1 and receives the power cut command from the hybrid control unit 13, and the battery management system ( A power relay assembly (PRA) 17 which intercepts power drawing of the battery system 1 according to the signal of 15) is included.

Therefore, when the impact force of the collision detection sensor 5 is greater than the reference value is detected, the airbag cushion is developed by the operation of the airbag module 3 as described above to physically protect the battery system 1 from the rear impact force. In addition, the hybrid control unit 13 instructs the battery management system 15 to cause the power relay assembly 17 to interrupt the external drawing power of the battery system 1, thereby allowing the battery system 1 It is possible to prevent the system damage of the vehicle and the injuries of passengers from being caused by the incorrect supply of power provided by.

While the present invention has been particularly shown and described with reference to specific embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the following claims It will be apparent to those of ordinary skill in the art.
