EPS inverter DC input part analysis - battery input terminal
The DC input part of EPS inverter is an important part of the entire emergency power system, which is responsible for providing stable DC power to the inverter, ensuring that it can be quickly switched to battery power mode when the mains is interrupted, and maintain the continuous operation of the load. This article will introduce the key link of DC input in detail: battery input.
Battery input
The battery input terminal is the core component of energy storage in the EPS system and usually consists of a set of batteries. These batteries are charged when the mains is normal and provide energy to the inverter when the mains is interrupted.
Main functions
Energy storage: When the mains is normal, the battery is charged through the rectifier charger to store electrical energy for emergency needs.
Automatic charge management: The system will automatically adjust the charging current and voltage according to the status of the battery, such as power, temperature, etc., to extend the service life of the battery.
Low power shutdown mode: When the difference between the charger input voltage and the battery voltage is less than 30mV, some charge management chips such as TP4056 will enter the low power shutdown mode to reduce energy consumption.
CONCLUSION
The battery input is the source of power for the EPS inverter and usually consists of a set of batteries. These batteries store electrical energy under normal conditions, and when the mains is interrupted, the batteries can quickly provide DC power to ensure the continuous operation of critical firefighting equipment.
