The key requirements of a good SAI battery maintenance program proposed by Renobat ®admin
The Battery Maintenance Program to be designed by Renobat ® will be a dynamic program that provides optimal information about the overall state of the batteries and a increased battery reliability for every Euro invested in Testing. This program combines the preventive, Predictive and corrective maintenance and will dynamically perform both State and performance tests throughout the battery life cycle, taking into account the criticality of the center, the age and size of the batteries and the results of previous Tests.
To design the optimal testing program for a specific battery bank, an objective comparison of the available test techniques is required. To make an objective comparison, users must first define parameters of what is expected or needed for battery maintenance.
In our analysis we have identified some key requirements that we explain BELOW.
1. Capacity Estimation: The main requirement of any battery is to provide the capacity necessary to support the load during the designated autonomy Time. The Full on-site download test is still the best way to measure Capacity. Partial discharge is not as accurate, and the internal resistance tests do not provide a measure of Capacity. Instead, they may indicate the probability that a cell will arrive or not reach its nominal capacity.
2. Detection of defective cells: Even in a new battery, a failure of an individual cell or mono block can lead to critical power loss. Detecting these failures allows optimum protection of the LOAD. While discharge tests provide an absolute test of cell condition, IR tests can detect early signs of failure before a critical loss of capacity occurs.
3. Estimation of remaining life: the lifespan of a valve-regulated lead acid battery is usually much lower than that envisaged in its DESIGN. It is affected by numerous variables, including temperature, load, early life defects and other Problems. With appropriate testing and development of state trends, the remaining shelf life can be estimated. With all this Renobat ® plans The substitutions before the failure of a battery causes a reduction or even the complete loss of the available autonomy time .
4. Correction of mechanical problems: connecting joints, belts and fittings require regular verification and correction, as well as physical problems such as acid leakage, cells or mono-swollen blocks, high temperature and other factors . This always requires a visit to the installation to correct problems, but, with the remote tests of the bonding resistances, it is possible to detect many joint failures and to allow a corrective response oriented.
5. Profitability: The results of each technique must provide a good return of the inverted OPEX. CAPEX in batteries is a significant investment, often higher than the DC plant it Supports. The ideal maintenance program designed by Renobat is capable of maximizing the life of the batteries so that the volume of CAPEX and total cost of ownership (TCO) can be Reduced.
6. Avoid risk of testing: With any battery test technique, It is important not to subject the load to unnecessary hazards. The techniques and procedures used should be designed to minimize this risk and maximize the available back-up power during the test procedure.
The ideal battery maintenance program proposed by Renobat ® would reach a score of 10/10 in each requirement of the exposed, taking into account that Renobat ® adapts to the needs and emergencies of each client
