Battery Management System (BMS)
The battery management system (BMS) is the core safety measure of the Energy Storage Battery Box. BMS can monitor the key parameters of the battery such as temperature, voltage, current, etc. in real time, and manage the battery's charge and discharge, thermal management, and balance management. When the battery is abnormal, the BMS can respond quickly and take corresponding protection measures, such as cutting off the power supply and reducing the charging current, to prevent safety accidents.
Overcharge and over-discharge protection
Overcharge and over-discharge are common safety hazards in battery systems. Overcharge may cause problems such as increased internal pressure and electrolyte leakage, while over-discharge may cause battery performance to decline and shorten life. Therefore, the Energy Storage Battery Box needs to be equipped with an overcharge and over-discharge protection circuit. When the battery power reaches the preset upper and lower limits, the charge and discharge circuit is automatically cut off to protect the battery from damage.
Short circuit protection
Short circuit is another common safety hazard in the battery system. When a short circuit occurs between the positive and negative poles of the battery, the current inside the battery will increase sharply, which may cause serious consequences such as battery heating and explosion. Therefore, the Energy Storage Battery Box needs to be equipped with a short-circuit protection circuit. When a short circuit is detected, the circuit is immediately cut off to prevent safety accidents.
Temperature protection
Temperature is an important factor affecting battery performance and safety. Too high or too low temperature may cause battery performance degradation, shorten life, and even cause safety accidents. Therefore, the Energy Storage Battery Box needs to be equipped with a temperature monitoring and control system to monitor the temperature of the battery in real time and take corresponding measures when the temperature is abnormal, such as starting the cooling system, reducing the charging current, etc., to keep the battery running within a suitable temperature range.
Fire retardant measures
The Energy Storage Battery Box also needs to take fire retardant measures to deal with possible fire accidents. This includes using flame retardant materials to manufacture battery boxes, setting up fire isolation belts, and installing fire extinguishers. Once a fire occurs, these measures can effectively delay the spread of the fire and buy time for rescue.
In summary, the safety protection measures of the Energy Storage Battery Box are a comprehensive system engineering, which needs to start from multiple aspects to ensure the stable operation and safety of the battery system.
