MDB-e monitoring and battery discharge

Industrial plants have installed back-up DC systems and AC UPS systems with large stationary battery strings typically ranging from 24Vdc to 240Vdc nominai system voltages at up to thousands of ampere-hour capacity.
The determination and verification of the battery performance is absolutely necessary in criticai industriai plants.
Battery capacity can degrade severely with the age of the battery and the rate of decrease of battery capacity is highly dependent upon the environmental and operating conditions.
Critical back-up systems are not always available for periodic battery testing and normally do not have the required in-built functioning to verify the true battery back-up capacity.
The MDB-e is a microcontroller-controlled system which allows the discharging of any battery bank with the typical system parameters in industriai plants. This discharging can be performed in constant current mode, constant power mode or by following a predefined discharge profile.
The MDB-e can be connected together with other MDB-e units in order to extend the tota I discharge current up to 1500A.
For the entire duration of a discharge test (up to 15 hours), data is memorized internally in the MDB-e. Up to 8 different discharge sessions can be memorized in this way and easily consulted for analysis, also using a connected PC.
During a discharge, the MDB-e constantly monitors essential battery parameters in order to stop a discharge currently in process in the case of a failure of the connected battery or a severe under-performance with respect to the predicted battery performance
