BMS****3
Battery Monitoring System
Real time knowledge about the battery
condition is very significant to ensure the performance of critical
power system. However, existing methods of manual measurement or
online battery monitoring system will require very complicated wire
connection, long time installation/commission, professional
technicians and also very high cost. Therefore, the investment is
pretty huge. Whats more, they do not have complete measurement data
to precisely predict battery capacity.
More than
Measurement Data!
BMS****3 series battery monitoring system is an
innovative solution to solve these problems. We apply new methods
to measure battery condition with communication way of power line
carrier (PLC). With multi-frequency measurement, users can analyze
battery in all aspects including internal resistance, voltage,
current, capacitance, temperature and so on. Based on Kongters
years experience for battery management, we build very mature
mathematical model that will precisely predict battery capacity.
This will in another hand reduce the time that we spend on capacity
measurement using a battery load bank.
With APP or Web page access based on Cloud
server, you could easily manage your batteries simply with a smart
phone remotely. Periodically you will receive very detailed
diagnostic report from Kongter indicating comprehensive data of
your battery with suggestions and solutions in case of weak
batteries.
System
Composition
The whole BMS****3 system is composed of two
basic hardware components and one software component. Hardware will
includeMonitoring
Terminal (MT) &Control
Unit (CU).
With Power Line Carrier (PLC) data
transmission, measurement data will be collected by MT simply via
battery straps and send to CU. It is no need to have extra time and
money consuming communication cable or any other wireless data
transmission. This enables the system to be installed in almost all
battery systems with very simple wire connection and it is
interference-free to battery system.
Monitoring Terminal
(MT)
-Communication with CU: PLC (optional:
RS**5)
-Cells
connected per MT:
One MT can be connected with 1, 4 or 6
depending on customers
requirement and different battery wiring
structure onsite.
-Function:
Test battery voltage, internal resistance,
capacitance & temperature and send
to CU via simply via power line carrier (PLC). It has battery
equalization function.
-Model
selection: *-channel, *-channel &
*-channel.
Control Unit (CU)
-Communication with
server: WiFi or
GPRS
-Communication with
MT: PLC
(optional: RS**5)
-Function:
Test string voltage, current and collect
measurement data from MT simply via power line carrier (PLC). And
it will send all data to cloud server via its built-in WiFi/GPRS
module.
Our
Advantages
1.Very
simple wire connection, easy-going installation and commission
onsite
-BMS****3
adopts the technology of Power Line Carrier (PLC) for data
transmission. It takes advantage of communication circuit of
battery string itself. Data of each cell will be transferred to CU
simply via battery straps and power line, no need to connect extra
wires or cables for data transmission. This saves you hours or even
days of onsite installation and commission.
- We use
cloud computing platform for data management. Users do not need to
purchase server or install server software by themselves. Just one
login account and password from Kongter will enable user to view
everything about their battery condition simply with a smart
phone.
2.Kongter
uses advanced mathematical model, consistent and
precise
-Kongter
has patented technology of multi-frequency measurement based on our
years experience for battery management. And we have built very
mature mathematical model that will precisely predict battery
capacity (SOH).
-Customized solutions to meet different users
in various applications. We have different types of monitoring
terminals (MT). They can be connected to 1 cell, 4 cells or 6 cells
each. Different terminals could be used for the same battery
string. This makes it very convenient and flexible for connection
with different types and wiring structure of batteries.
3.Cloud
server + mobile communication
-All you
need is a smart phone to view battery status and all detailed
information.
-Timely
SMS warning info keeps you alert for lag-out or weak batteries.
4.Smart
and convenient methods for battery
management
-Complete
monitoring and recording for voltage, internal resistance,
temperature and periodical monitoring for charge/discharge current.
It helps you find out lag-out batteries beforehand.
-In case
of power grid outage or manual switch-off of power grid for
maintenance, system will automatically switch to discharge monitor.
And it will record discharged Ah and voltage/temperature changes
during discharge. This will further help judge the lag-out
batteries.
-In case
of battery malfunction, system will automatically send warning
message to technician for immediate action.
-Map
orientation of battery sites will help technicians reach site
conveniently.
5.Online
battery equalization
-Battery
equalization controls battery charge and discharge, effectively
extend battery life.
6.Unique
technology for system resting
-Each MT
gets very low power from batteries, no harmful to batteries that
are monitored.
7.More
than measurement data, you get solutions
- Every month, you will get a very detailed
analyzing report from Kongter. This report will analyze all battery
conditions completely. In case of battery failures, we will provide
solutions in the report. This will enhance the reliability of your
system. You do not also need to go the site for manual inspection
and measurement. It saves your time and
manpower.
Our Unique
Battery Measurement Technology
Kongter has patented technology of
multi-frequency measurement based on our years experience for
battery management. And we have built very mature mathematical
model that will precisely predict battery capacity
(SOH).
In our battery model, we use the method of
AC discharge under different frequencies. We will measure different
parameters and their changing tendency in battery charge and
discharge.
In this diagram, it is a process of firstly
battery discharge and then charge. Electrical double-layer
capacitance (C2) is very sensitive to battery capacity. And battery
electrochemical resistance (R2) is very sensitive to chemical
reaction during battery charging. It could be adopted to indicate
if battery is full charged or not, which will avoid over charge
that will decrease battery life due to hydrolysis reaction.
Meanwhile, considering that battery aging will also decrease its
voltage after full-charge, we will take voltage, ohmic resistance,
electrochemical resistance and electrical double-layer capacitance
as variable, and thus build thefunctional
relation as the formula below:
Soh=f(V,R1,R2,C2)
We build the mathematical model based the
parameters of V, R1,R2 and
C2. Based on the experimental statistic and method of system
identification, we will identify the parameter in this mathematical
model. We will measure and gain values for parameter of V, R1, R2
and C2 under battery full charge or float charge. After
substitution these values in the formula above, we will gain the
value for SOH which is very close to capacity measurement that is
done by a regular battery discharge.
Onsite installation of measurement
cables
For different styles of battery
inter-connection onsite, Kongter offers various options of
connectors for fast connection of MT with battery posts or battery
straps. You could either install the monitoring system when
batteries are online or offline. This greatly simplifies onsite
installation. Temperature sensor is built-in the measurement cables
to record temperature of each cell.
