(Data centers for key departments, civil aviation, banks and financial institutions, hospitals, military, government departments, etc.)
Eto provides a series of solutions for data center battery monitoring and maintenance solutions, ensuring The data center operates normally and efficiently. Today's instantaneous and constant data transfer requires no server downtime. When the mains power fails, the backup battery is the most important preventive facility for the server to keep it from shutting down. Monitor the health status of the battery and eliminate battery failures in advance to ensure that the system can operate normally when the mains power is interrupted. SBM-2000 series battery internal resistance tester adopts single large current discharge method testing technology to quickly, safely and accurately measure the internal resistance of the battery and the connection resistance between batteries. It is widely used in nickel-cadmium batteries (1V alkaline batteries) , Testing and maintenance of lead-acid batteries (2V single, 4V, 6V, 12 modules), iron lithium batteries (3V). The SBM-3000 series battery internal resistance tester still uses the single large current discharge method testing technology of the SBM-1000 series and SBM-2000 series. Added connection voltage drop test, microohmmeter function (optional microohmmeter accessory), and U disk storage function. It has strong anti-interference ability and is suitable for battery testing of large UPS.
The battery internal resistance tester is one of the instruments in the world that can accurately and effectively measure battery internal resistance. It is widely used in rapid battery performance testing, daily battery maintenance, battery installation project acceptance and battery manufacturers. Quality inspection, etc.
It is recognized by the global battery industry and the UPS industry that the battery online monitoring system with DC internal resistance testing function is the best tool to avoid blind spots in battery maintenance testing, and is also an important guarantee for UPS reliability. BMMS-2000 battery monitoring system is an advanced comprehensive application of eTocsin's proprietary technology of single instantaneous high current method internal resistance testing and other technologies. It is unique in that it provides early warning when the battery is first showing signs of aging. By monitoring the battery's internal resistance and other parameters, the system knows the status of each battery cell at every moment. Therefore, the system not only understands the current performance of the battery pack, but also predicts future trends. System functions include monitoring of daily operating parameters of the battery (float voltage, battery pack voltage, ambient temperature, charge and discharge current, etc.), monitoring of battery performance parameters (internal resistance, connection resistance) and capacity testing (optional load box), It is a battery operation monitoring system with comprehensive performance.
2.1 Battery Online Monitoring and Management System (Networked BMMS-2000)
Internet Data Centers (IDCs) usually have multiple UPS systems, battery banks that start backup generators, and switches Battery systems for power supplies, and battery packs for fire protection and security systems. Such a large number of battery packs makes monitoring very complicated. What makes BMMS-2000 unique is that it can connect various dispersed monitoring subsystems to the network and manage them uniformly by the supervisory computer. As shown in the figure above, the supervisor computer manages multiple monitoring subsystems in a unified manner. The supervisory computer can be any computer in the network connected to the BMMS, but a system can only have one supervisory computer. All monitored data are stored in the database of the supervisory computer. The SLU series AC/DC smart load box is a fully automatic smart discharge box that uses resistance adjustment for constant current/constant power control. The SLU series includes DC series, AC series, and AC-DC general-purpose series. Suitable for discharge testing of battery packs, DC power supplies, AC power supplies, and UPS systems. Contains software and hardware dual automatic protection functions for overcurrent, overvoltage, overtemperature and reverse polarity; with diagnostic and correction functions;
AC SLU-AC series smart load boxes are classic resistance-adjustable constant current/constant power Purely resistive AC load. Discharge parameters such as discharge current/power, discharge time, and termination voltage can all be programmed. All parameters and status during the discharge process are displayed in real time.

Discharge parameters such as discharge current/power, discharge time, termination voltage, and discharge rate can be programmed. All parameters and status during the discharge process are displayed in real time. Friendly human-machine interface, simple style screen and buttons, easy to operate. The internal resistance and short-circuit current of fixed lead-acid batteries, and the high current capability of 30I10 are the main important parameters of its performance. Until now, these parameters can only be set up in a few laboratories using simple means to test the internal resistance and short-circuit current and 30I10's high current capability in a small ampere-hour, near-constant current mode. Because the control methods are relatively rough. Or it is manual control, and the consistency and accuracy of parameters are not high. Since the internal resistance parameters of the battery are not only used to consider the load capacity of the battery and design the power system for short circuit safety, it has also been widely used for the consistency inspection and operation maintenance of fixed lead-acid batteries. The test accuracy and repeatability of this parameter are particularly important. A set of high-precision, intelligent fixed lead-acid battery internal resistance and short-circuit current testing equipment that complies with the IEC60869 standard (GB/T19638) is very urgent.
Yito BTS series lead-acid battery testing system fully complies with the testing methods of IEC60869 and GB/T19638 standards, providing internal resistance and short-circuit current of fixed lead-acid batteries within 3000AH, 30I10 high current resistance and Testing of electrical properties (such as capacity, cycle ability, overcharge ability, etc.) specified by other standards. It provides an effective means of standard test value verification for battery internal resistance testing devices or instruments used in the field, and lays a solid foundation for popularizing internal resistance parameters for consistency testing and daily operation and maintenance of fixed lead-acid batteries. BTS-2013 passed the certification test of China National Laboratory Cape Laboratory. There has been no suitable equipment to test ultra-large current circuit breakers with operating currents of several thousand or even tens of thousands of amps. This troubles the power department's annual maintenance work. The on-state voltage drop and current value of ultra-large current circuit breakers are not completely linear. The 200A test current used is far from the actual working status of the circuit breaker. Moreover, for a circuit breaker with an operating current of over 10,000 amps, a test current of 200A can only produce a voltage drop of about 1mV. The accuracy of such measurements is also in question. The HCT ultra-high current circuit breaker access test system can provide a DC test current of more than 10,000 amps, which fully matches the working status of the circuit breaker, and measures the voltage drop under ultra-large current to obtain the true performance of the circuit breaker.
