Our solution is very flexible for the number of strings, and we can increase or decrease it ourselves;
The system runs independently and is a passive system, the host does not need to move, the number of acquisition modules is automatically identified, and it cannot communicate with other inverters;
Every time there are more than 12 strings, an acquisition module can be added, and all protection parameters can be set freely. As long as the battery voltage is within 5V, it can be used;
There is no limit to the battery type, and different protection parameters can be modified to match different types of batteries;
Flexibility is very high;
Shipping List on the pciture is option: ?Host*1pcs, ?Acquisition Module*7pcs
(Different option has with correcspondent cables and Cureent transfer)
Each acquisition module can be connected to a maximum of 12 strings, 12x8=96 strings, as long as the total voltage is within 1000v, it can be extended in series.
1. Real-time monitoring of 4-96 series single-cell voltage, which can be cascaded infinitely. At present, the host only supports 8 modules. Modularization is adopted. , so the total voltage of the batteries connected in series with a single module cannot be less than 11v. If the battery is less than 12 strings, the redundant detection channels must be connected in parallel to the positive pole of the highest battery of the module), and the total voltage of a single module input in series shall not be higher than 75v, the detection range of a single channel is 0--5v, and the input voltage of the host control part should not exceed 60v.
2. Monitor the total voltage, charge and discharge current, power, temperature of the battery pack in real time and count the actual charge and discharge capacity in ah. The host has a temperature detection to monitor the temperature of the mos tube, and each module comes with a temperature detection, a total of 9 temperature detections.
3. With overshoot, over-discharge, over-current, over-temperature protection.
4. Display the percentage of remaining capacity in real time and display it with a progress bar.
5. High voltage 200V rated long-term working current is 30A, instantaneous short-time 60A, low-voltage rated continuous working current is 70A, instantaneous short-time 100A, high voltage and current can use relay scheme, details can be discussed in detail, long-term constant high current The work needs to strengthen the heat dissipation of the mos tube.
6. Running flashing indication, prompting the system running status, 3.5-inch IPS color display, ultra-wide viewing angle, the working status is clear at a glance.
7. With the current manual calibration function, because the voltage measurement error is 1.2mv total measurement error, so no calibration is required.
8. The charging and discharging are designed with the same port to reduce the connection line.
9. The number of connection strings is expanded by module cascade connection, which can theoretically be expanded infinitely. Two-core cat5 twisted pair is used to connect the host and the module, and the communication between the module and the module, and the cable length can reach 40 meters (this length is the laboratory The effective length of the actual test in the environment, if the field interference is large or the wire selection is not suitable, the communication distance should be shortened accordingly).
10. After the host is turned off, the module automatically goes to sleep, and the power consumption is only 4ua. The modularization can also shorten the length of the balance line, so that the host and the module, and between the module and the module can be placed at a long distance.
11. The module has an automatic balancing function, which is balanced until the voltage drop stops at 0.001v, and the balancing current is 200ma. This function must be turned on after the battery is fully charged. Balanced discharge will generate a lot of heat, so you need to pay attention to the heat dissipation of the module.
12. Fully isolated design, all interfaces can be hot-swapped, and the temperature sensor can be disconnected if it is not used.
13. If you think the alarm buzzer sound is small, you can tear off the sticker on the surface, and the sound will be loud.
The two-layer board of the main board is superimposed, the size is 135x57mm, and the thickness of the stack is 45mm, excluding the size of the radiator.
Module size 82x72mm, stack thickness 13.8mm
14. Using Bluetooth 4.0 to connect with the mobile APP, all parameters are clear at a glance, and the host parameters can be modified through the mobile phone
15、After the input terminal is connected to the charger, it will automatically enter
the charging state, and count the actual capacity, and display the charging current
and power at the same time. With the increase of the charging capacity, the
originally used capacity will gradually reduce, and the progress bar will act
synchronously with the change of capacity.
16、The BMS supports mobile app, which monitors and controls any status and
parameters of the host through Bluetooth. When protection occurs, the mobile
phone has the query of protection history, and the reason for the last protection can
be queried.
17、At present, the host has 14 tube version, 28 tube version and relay
version. The relay version supports two connection methods of the same
port and the separate port, and supports the use of Hall current sensor。
18、The BMS has automatic control function of charge and discharge.
After charging protection, as long as the discharge current is detected to
be greater than 200mA, the charging port will be opened automatically
to prepare for the next charging. After discharging protection, if the
current of charging equipment is detected to be greater than 200mA, the
discharge channel will be opened automatically, and the whole process
will be completed automatically. In case of safety problems such as
over-current protection, over-temperature protection and wrong
number of battery strings, The charge and discharge MOS tube is closed
at the same time. At this time, the channel must be opened manually
after troubleshooting.
19、The host instrument displays the current supported range, the
maximum current is 999.9a, the maximum capacity is 6500ah, and the
maximum power is 65000w

Note 1：When the battery pack is 16, the spare ports must all be short
circuited to the positive pole of the last battery of the module, the
specific connection is as follows：
Note2：When the number of battery cells is 13, 14, 15, 25, 26, 27, 37, 38,
39, the power supply voltage of a single module must be 11V. For lithium
iron phosphate and lithium ternary, it must be up to 4 to make the
Host power input 8-60v

In addition to the above special cases, other combinations can be
connected from low position to high position successively
