Ссылку в студию пожалуйста. Я что то дешевле 60т.р. не встречал.
Один требует сылки на ОпенСоурс контроллеры, второй на Дешманские BMS
Вам нужны пруфы ? вот вам фото из тех документации на контроллер
И описание на кит. через гугл
Performance and parameters:
1. Real-time monitoring of 4-96 series single unit voltage, cumulative total voltage 403V, single module tube
Maximum 12 strings and minimum 4 strings (since the power supply of the module is from the battery, so a single module
The total block voltage shall not be less than 11V, and all unused channels shall be connected to a single mode.
The maximum positive pole of a cell, the total input voltage of a single module shall not exceed 75V, a single section.
The monitoring voltage range is 0 - 5V, and the total input voltage of the main engine should not exceed 60V.
2. Real-time monitoring of total voltage, charging and discharging current, power and temperature and statistical analysis of actual discharging ah Amperes
At the same time, the host computer has one way to measure the real-time temperature of the MOS transistor. Each module has one way to measure the temperature.
Detection, a total of 9 channels of temperature detection;
3. Single cell voltage is lower than protection setting value, total current is higher than protection setting value, and cut off
Output to protect the battery pack from overdischarge, any section of the voltage during charging is higher than the protection setting.
Value, charging current higher than protection setting value, cut off input when the temperature of battery or MOS transistor exceeds
Overset the value, cut off the charge and discharge channel;
4. Real-time display of the remaining percentage of capacity and the remaining capacity, and display with graphical progress bar;
5. Running lamp indication, prompting system operation status;
6. The rated high-voltage control output current for long-term operation is within 30A, and the maximum is 70A in a short instant.
Low voltage rated 70A, instantaneous 100A (long time constant high current work needs to strengthen heat dissipation);
7, 3.5 inch IPS color screen display, ultra-wide perspective, working status at a glance;
8. With the function of current calibration, the total voltage error is 1.2MV, so there is no need for it.
9. Charge and discharge design of the same port, eliminating the need to connect a lot of wires;
10. Module cascade structure, two-core CAT5 twisted-pair connection, length up to 40
The length is measured by the CAT5 network line in the laboratory environment, if disturbed on site.
Large or inappropriate wire selection, the actual communication distance should be shortened, so that the host and module,
Modules and modules can be placed over long distances;
11. The shutdown module of the host will go to sleep. The power consumption of the module is only 4UA, and it will not.
It causes the loss of battery power and can be installed close to the battery, reducing the length of the balance line and
12. The module has the function of automatic battery balancing, balancing the voltage drop of the battery until it is balanced.
When the drop is 0.001 V, the function must be balanced automatically when the battery is full.
The balance discharge current is 200MA, which will emit a lot of heat when equalizing. It is necessary to pay attention to the module dispersion.
13. Full isolation design, all interfaces can be hot plugged, temperature sensors can not be used
Not to insert;
14. Active heat dissipation, when the temperature of the main MOS tube exceeds 50 degrees, automatically start the fan for strong.
Air-cooled heat dissipation, to prevent high temperature caused MOS tube burst;
15. After the input terminal is connected to the charger, it automatically enters the charging state and counts the actual charging capacity.
Volume, charge current and power are also displayed. With the increase of impulse capacity, the original used.
The capacity decreases gradually, and the progress bar moves synchronously with the change of capacity.
Цена контроллера около 250 дол.
