Common fault phenomena and solutions of electric vehicle battery current sensors

2025-04-30

Imagine: at a critical moment, your electric vehicle battery management system (BMS) suddenly issues an “abnormal current” alarm, while you lose power without warning. The battery current sensor is like the “current eye” of a car. Once there is a problem, it not only affects the range but may also pose safety hazards. Only by understanding its “temperament” and “deviation” can we extinguish the fire of malfunction in the first time and ensure worry free driving. 1、 Introduction to Electric Vehicle Battery Current SensorThe current sensor is responsible for real-time monitoring of the charging and discharging current of the battery pack, and is the core component of BMS for accurately estimating the remaining charge (SOC) and state of health (SOH). Common types include Hall sensors and shunt sensors, each with its own advantages and disadvantages – Hall sensors have strong anti-interference ability but slightly lower accuracy, while shunt sensors have high accuracy but require good heat dissipation.2、 Common fault problems and solutionsCorresponding measures for fault phenomenaSignal drift, jitter • Check and stabilize power supply and grounding

Adhesive for weighing sensors

2025-04-27

1、 The concept and working principle of weighing sensorsWhat is a weighing sensor:A weighing sensor is actually a device that converts a mass signal into a measurable electrical signal output working principle:In principle, a weighing sensor is a pressure sensor, which is encapsulated in metal. It has an eddy current triggering winding and a sensor that senses the intensity of the eddy current. The eddy current is inside it, and when the metal is compressed, it deforms, causing the eddy current to change. After amplification, the data can be read.3 common weighing sensors:Weighing sensors can be divided into 8 categories according to conversion methods, including photoelectric, hydraulic, electromagnetic, capacitive, magnetic pole transformation, vibration, gyroscope ritual, and resistance strain, with resistance strain being the most widely used. Taking the resistance strain type weighing sensor as an example, we will share with you the working principle and adhesive points of the weighing sensor. Working principle diagram of resistance strain type weighing sensorA resistance strain sensor is a measuring device that uses a metal elastic body as the elastic element and a resistance strain gauge attached to the sensitive part of the elastic body to form a Wheatstone bridge. Under the excitation of an external power source, the force can be converted into an electrical signal. Usually, elastomers and strain gauges are combined in various ways, such as shells, sealing components, etc., to protect the strain gauges.The resistance strain sensor is mainly composed of elastic body, strain gauge, Wheatstone circuit, compensation circuit, cable, adhesive, and sealing material.2、 Common materials for weighing sensorsThe performance of a weighing sensor largely depends on the choice of manufacturing materials. The weighing sensor material includes the following parts: strain gauge material, elastomer material, patch adhesive material, sealant material, lead sealing material, and lead material.

Case Study of Silicon Adhesive: Efficient Solution for Enhancing Inductance Reinforcement of Controller Circuit Boards

2025-04-23

BackgroundIn modern electronic devices, the controller circuit board is one of the core components, and its performance stability and reliability directly affect the operational efficiency of the entire system. However, in practical applications, due to the complex and variable working environment (such as temperature fluctuations, vibrations, etc.), the inductive components on the controller circuit board are easily affected by external factors and may become loose or damaged, thereby affecting the normal operation of the entire system. Therefore, how to effectively enhance the stability of these key components has become an urgent problem to be solved. ChallengeRapid curing requirement: In order to not affect production efficiency, the reinforcement material used must be able to complete the curing process in a short period of time.Fluid characteristic requirements: The ideal reinforcement material should have good flowability so that it can evenly cover around the inductor without unnecessary diffusion due to excessive flow.Strong environmental adaptability: considering the various use scenarios that electronic products may face, reinforcement materials also need to have excellent temperature resistance and aging resistance.SolutionAfter comprehensive consideration, we have chosen SIPC 1823 silicone adhesive sealant as the solution for this project.

Elaplus shares the sealing of car vent tank connectors

2025-04-23

In the automotive industry, the pneumatic system (commonly known as the “vent tank” or energy storage tank) is a key component that ensures the overall power response and smoothness of the vehicle. The inside of the vent tank often needs to maintain a high pressure of 35-40 Bar and withstand a wide temperature cycle test from -40 ℃ to 100 ℃. And the various connectors (sensor interfaces, solenoid valve interfaces, etc.) directly connected to the tank are the “throat” of the entire system: once the seal fails, it will cause air pressure leakage, system failure, and even endanger the safety and stability of the entire vehicle in severe cases. Therefore, selecting the appropriate sealing material for the automobile vent tank connector has become a technical challenge that vehicle manufacturers and component suppliers must focus on overcoming. 1、 Project BackgroundApplication scenariosComponent location: Gas tank assembly near or on the chassis of the vehicle;Working medium: Vehicle mounted high-pressure nitrogen or compressed air;Work pressure: 35 Bar to 40 Bar (normal operating and safety reserve pressure);Temperature range: -40 ° C (starting in cold conditions) to -100 ° C (engine compartment high temperature superposition);Vibration and impact: The combination of road bumps and engine vibrations during vehicle operation.Project objectivesEnsure that the connector is sealed without leakage under the long-term action of high-pressure gas;Maintain reliability even after meeting extreme high and low temperature cycles;Realize rapid solidification and improve production efficiency;Control material and process costs to meet the requirements of mass assembly of parts.2、 Main challenges
