Blasting Value Explanation of Electric Vehicle Prismatic Battery Safety Vents
The electric vehicles prismatic battery safety vents protect the battery from exploding due to overvoltage or overheating during charging, discharging or abnormal working conditions. This article will detail the concept, principle, blasting value and application scenarios of prismatic battery safety vents to deepen the understanding of this technology.
The Concepts and Principles of New Energy Vehicle Prismatic Battery Safety Vents
New energy vehicle battery safety vents are valves used in battery modules or energy storage equipment. Its primary function is to monitor the pressure and temperature inside the battery. When the pressure or temperature exceeds the set value, the safety vents will rupture from the notch and release the pressure to reduce the pressure inside the battery and avoid explosion accidents.
The Blasting Value of EV Battery Safety Vents
The blasting value of the new energy battery safety vents is the set value of the pressure or temperature at which the valve opens. The setting value is usually determined based on the specific battery type, capacity and working conditions. This time, we mainly focus on the pressure burst value.
Pressure Blasting Value
Pressure blasting value is usually expressed in Pascal (Pa), according to the battery’s working conditions and safety standards.
The blasting value of a new energy battery safety vent refers to the pressure threshold at which the safety vents suddenly open and release the internal gas after bearing a certain pressure. Generally speaking, the explosion value of new energy battery safety vents is 0.5-1.0MPa.
Choice of Blasting Value
- Battery type and usage scenario
The selection of the blasting value needs to be determined based on the specific battery type and usage scenario. Factors such as the battery’s maximum charging and discharging pressure, temperature rise, and current should be considered.
- Safety Vents’ Manufacturing process and Material Characteristics
The selection of the burst value also needs to consider the manufacturing process and material characteristics of the safety vents to ensure that the safety vents can reliably open and release the internal gas within a specific range and to ensure that the safety vents themselves will not fail or be damaged due to the selection of the burst value.
However, The blasting value of battery safety vents is usually determined through engineering design, and the specific value will vary according to different battery types and design requirements. Generally speaking, the blasting value will be determined based on the maximum working pressure of the battery and the pressure resistance of the material to ensure that it can work safely within the normal working pressure range. When the pressure exceeds the safe range, it can be opened in time to release the pressure and avoid the battery explosion caused by excessive pressure.
