Efficient Balancing Battery Management System

Image
Efficient balancing battery management system: passive equalization is pure electric and hybrid in the most widely used in a balanced way, with low cost and high reliability. With the repeated charging and discharging of the battery pack due to inconsistencies between the internal resistance of the battery, the battery will generate pressure, if not treated, pressure will grow increasingly common industry practice is a parallel resistor voltage consumed high energy batteries. The traditional way of cooling and air resistance is the direct contact with the heat conduction out quickly difficult. Efficient balancing battery management system is based on aluminum plate cooling technology and single-cell capacity equalization offset correction technology management system, this product can be efficiently accurate balanced management of lithium batteries. Traditional battery management system generally is about balancing the current 60mA, this product uses aluminum plate mount balan

Three Reasons of Lithium-ion Battery of Fire or Explosion

Image
One of the main power supply computers and other portable electronic products. However, lithium-ion battery charging and discharging process because of improper use can be dangerous and explosion; especially under abuse conditions (such as heat, overcharge, short circuit, vibration, compression, etc.), the battery will be a fire, explosion or even staff injuries and so on. Therefore, the study of the explosion mechanism of lithium-ion batteries to improve the safety of lithium-ion batteries has important significance. Lithium-ion battery fire or explosion three possibilities, with the following three. First, when the lithium-ion battery to heat, the reaction inside the battery, such as a chain reaction, each reaction and promote each other, in turn. First, the SEI film decomposition exothermic heating battery, prompting a negative reaction to the solvent release more heat, resulting in a negative reaction with a binder, and solvent decomposition, then followed by the positive ter

Why Sotrage Battery Need BMS

Remote meter equipment due to its special working conditions and work requirements of the battery is very high. It requires the battery has a longer continuous power supply capacity, battery life time is often needed to reach a year or even longer.Because of the lithium batteries high voltage, small size, light weight, high energy density, no memory effect, no pollution, low self-discharge, long cycle life, the many advantages of being widely used in remote monitoring long standby instrument. Compared with nickel-metal hydride batteries, lithium-ion battery 30%-40% lighter, energy 60% higher than it. However, lithium also has serious flaws, is summarized in the following two aspects: Safety Lithium battery security is poor, when an explosion and other defects. Especially lithium cobalt oxide cathode materials for lithium batteries can not be high-current discharge, poor security. In addition, almost all kinds of lithium battery overcharge or over-discharge can cause irreversible

Function of Solar Energy Battery and How to Choose

Image
The function of solar energy battery The role of the solar energy storage battery module is to convert solar energy into electrical energy supplied to the load of work or to the lifePo4 battery pack; the role of the controller is a battery charge and discharge protection; lifePo4 battery for storing electrical energy; the role of the inverter is DC converted into alternating current. At night or rainy days, when the solar cell does not work, powered by a solar energy battery storage to the work load. Solar energy battery work can be divided into two recycling and the use of float. Often in frequent charging and discharging state, that is recycled; often in a state of charge of the float was used to make up for the loss of battery capacity due to self-discharge caused. PV system with VRLA batteries are recycled in a manner. Composed of photovoltaic systems, photovoltaic off-grid system is the use of the principle of the photoelectric effect to convert solar energy to electrical
