Structural principle of battery management system The battery management system is mainly composed of a charging module, a data acquisition module (including voltage, current, and temperature data acquisition), a balance module, a power calculation module, a data display module, and a storage communication module. It mainly manages and protects the use of the battery pack. Battery Management System Architecture The battery management system (bMS) involves microcomputer technology and detection technology,

What is the process technology of lithium battery diaphragm industry? Lithium-ion battery separators have complex processing techniques and high technical barriers. Lithium-ion battery separator is a critical inner layer component in a lithium-ion battery. Key properties such as battery capacity, cycle performance, and charge-discharge current density all have a direct relationship with the diaphragm, and the improvement of the performance of the diaphragm plays an important role in improving the overall performanc

What is a lithium-ion battery pack balance maintenance instrument? what is it used for? With the rapid expansion of the new energy vehicle market, the phenomenon of "squatting" in the use of urban electric buses has become prominent. This not only shortens the cruising range of new energy vehicles, but also affects the service life of electric vehicles due to the "premature aging" of battery life. Lithium-ion battery balance maintenance instrument is a portable product for dealing with outdated

The demand for lithium-ion battery management chips is strong, and the market is expected to continue to rise. With the acceleration of the popularization of mobile phone fast charging applications, the demand for accurate measurement of lithium-ion battery management chips has increased. A higher proportion of high-end mobile phones will use lithium-ion battery metering chips. In the past, some mobile phones used software to calculate battery capacity, which may not be able to meet the fast Comply with the specifi

Functions of power lithium-ion battery thermal management system Too high or too low temperature will directly affect the service life and performance of the power lithium-ion battery, and may lead to safety problems of the battery system, and the long-term uneven distribution of the temperature field in the battery box will cause various battery modules, unit The performance of the body is not balanced, therefore, the battery thermal management system is necessary for the electric vehicle power lithium-ion batt

The mining and production of lithium-ion battery raw material resources mainly include lithium-ion resources, cobalt resources and graphite. Energy density, cost, safety, thermal stability, and cycle life are the five key indicators of power lithium-ion batteries. Ternary materials, potassium manganate and lithium iron phosphate have no absolute advantages in these five aspects. Lead to the difference in the route of power lithium-ion battery electrode materials. The design of a battery starts with the select

1. The lithium-ion battery of the self-balancing car should be charged with a special charger. The charging of each charger is different. The charger cannot be replaced at will, otherwise it will easily cause damage to the battery. 2. Cultivate the habit of charging more every day. Although a single charge can be used for several hours, or even longer, it is still necessary to develop the habit of charging every day, so that the battery is in a shallow circulation state, which is very beneficial to extend the se

Stirring, coating, winding, and testing are important processing techniques for lithium batteries. 1. Slurry stirring is an important part of lithium battery equipment. Lithium battery positive electrode slurry is composed of binder, conductive agent, positive electrode material, etc., negative electrode slurry is composed of adhesive, graphite carbon powder, etc.; positive and negative electrode slurry The preparation of the slurry includes the mutual mixing, dissolution, and dispersion of liquid and liquid, li

The circuit has the functions of overcharge protection, overdischarge protection, overcurrent protection and short circuit protection. Its working principle is broken down as follows: normal status In the normal state, the "CO" and "DO" pins of N1 in the circuit both output high voltage, the two MOSFETs are in the conduction state, and the battery can be charged and discharged freely, because the conduction resistance of the MOSFET is very small, usually less than 30 milliohms, so its on-r
