Specifications of 3 Series LiFePO4 Batteries Charge & Discharge Guard Shield
Application:
The product could be widely used in the fields of electric devices, electric vehicles, standby power supply and power supply of military equipment, etc.
Main Functions:
The product has 6 main functions: over charge, over discharge, over current, short circuits, balancing and low-current lock.Function of over charge protection: once voltage of any battery in the group gets higher than the over charge protection point, charge cuts off to ensure all batteries work within the over charge protection point. Function of over discharge: once voltage of any battery in the group gets lower than the over charge protection point, discharge cuts off to ensure all batteries work beyond the over charge protection point. Function of over current: during the discharge process of battery group, once discharge current gets over the set over current protection point, output cuts off to ensure battery group works within the safe limit of current. Function of short circuit protection: once battery group’s output port appears the condition of short circuit, it cuts off to ensure battery group not to be damaged because of short circuit. Function of voltage balancing: in the late charging period of battery group, voltage difference that appears during the using process of each battery could get balancing revised to ensure battery group’s capacitance. Function of low-current lock: series connection of low-current lock gets reserved and low current controls on-and-off of the main high current to make it safer and more convenient.
