Description

1 TARIFF A DISCHARGE SYSTEM Technical Area This invention enables the rapid and efficient recovery of high voltages generated during accidents in electric vehicles. It is related to a system that ensures safe discharge. Previous Technique In electric vehicles, the energy source is HV (high voltage). The batteries are electrically disconnected from the vehicle during an accident. However, the energy storage Even if other HV components (components) that have systems are separated from the battery They are able to remain energized. Depending on the severity of the accident, the amount of energy they carry depends on the circumstances. HV discharge 15 in case of damage to components or HV cables. It is extremely important that the system be launched immediately. Therefore, in electric vehicles, the high voltages generated during an accident are released quickly and a system is needed that ensures safe discharge It is understood. 20 International patent number WO2013116678A2, which is included in the prior art. The document states that the vehicle battery is charged when the airbag sensor signal is triggered. a configuration designed to allow discharge through capacitors The system is being discussed. In an application example, a discharge of 25 for a vehicle. The control system uses an energy storage device supported by the vehicle, a switch, a primary load that can be selectively connected to an energy storage device, a memory where program instructions are stored and operational memory is accessed via a switch connected and executing program instructions to the energy storage device operationally 30 to the first load based on a defined heat generation rate. 2 to check the switch to ensure it is in a connected state It includes a structured control unit. Brief Description of the Invention The aim of this invention is to quickly reduce the high voltages generated during accidents in electric vehicles. and to create a system that ensures its safe discharge. Detailed Description of the Invention A "Discharge System" has been implemented to achieve the purpose of this invention, as shown in the attached document. as shown, these figures; Figure 1 shows a schematic view of the system that is the subject of the invention.

To transmit a PWM signal to the EDU (3) continuously at a specific frequency (e.g., 10 Hz). It is structured in such a way that when an accident is detected, the ACM (2) PWM to increase the frequency of the signal and EDU (3) detects that there is an accident and the accident The algorithm requires signals at different frequencies in two different periods to be activated. It is structured to transmit. In a sample arrangement of the invention, ACM (2) first 10 at 500 Hz frequency for the first five periods, and then at 250 Hz frequency for the next five periods. It is configured to transmit signals. The EDU (3) in the system (1) which is the subject of the invention is located inside the vehicle. and the PWM signals transmitted by ACM (2) and the frequency of the signals 15 It is structured to detect the change. EDU (3) by ACM (2) The accident is triggered by a high-frequency PWM signal transmitted in the second period. The situation is configured to run the algorithm. EDU (3) accident to verify the signals transmitted by ACM (2) with the algorithm and the actual accident It is structured to determine whether or not it is. EDU (3) accident algorithm 20 After a certain period of time (e.g., 20 ms) after starting operation, the capacitors it possesses to initiate the discharge process via the electric motor and the electricity to enable the capacitors connected to the motor to absorb the high voltage It is configured. EDU (3) monitors the PWM signal during the discharge time. It is structured in such a way that the high voltage in the vehicle is gradually increased to 25. reducing and converting electrical energy with the help of motor windings and capacitors.
