Maintanance of a car battery?4 answersThe maintenance of a car battery involves various techniques and systems to optimize its performance and prolong its lifespan. One approach is the use of a battery management system that controls the power supply to the battery and prevents it from being completely discharged. Another method is the implementation of a battery maintenance device that eliminates moisture and ensures the battery operates in the best state. Additionally, an electronic control unit can monitor the operational properties of the battery and provide recommendations for maintenance operations, such as reducing the frequency of charging. An intelligent remote maintenance system allows for remote monitoring and control of the battery, enabling maintenance operations to be performed efficiently. Furthermore, predictive maintenance techniques, such as the use of artificial neural networks, can analyze the operating parameters of the battery over time and generate suggestions for maintenance services.
What's the voltage?5 answersThe voltage measurement devices described in the abstracts are used to measure the voltages of multiple cells or batteries connected in series. These devices employ voltage detection circuits that communicate with each other to transfer communication commands and measure the cell or battery voltages accurately. The voltage obtained in one study is a logarithmic function of the vapor pressure of water sorbed by the support, resulting in millivolt-level voltages at specific relative pressures and temperatures. Another study focuses on correcting detection errors between voltage detection units by using a second voltage detection unit with higher precision but lower speed, and a correction unit based on stored error information. Additionally, a voltage measurement device is described that includes switch circuits and a capacitor to individually measure the voltage of power storage elements connected in series.
What is the mass of the battery in an electric vehicle?5 answersThe mass of the battery in an electric vehicle can vary depending on the model and capacity of the battery. Initially, electric vehicles used battery packs with an average capacity of 16-22 kWh, resulting in a certain weight for the vehicle. However, research has shown that the distribution of battery mass on the vehicle floor and the ratio between battery mass and vehicle body mass can significantly impact the movement safety of the electric vehicle. Different types of batteries, such as lead-acid, nickel-zinc, nickel-iron, and lithium sulfide, have been considered for electric vehicles, each with its own weight and range capabilities. Therefore, the mass of the battery in an electric vehicle can vary depending on factors such as battery capacity, type of battery, and the desired range and safety requirements of the vehicle.
