1	Fault	BMS is in sleep state, press the key (3 ~ 6S) and release it, the protection board is activated, and the LED indicator lights up successively from "run" for 0.5 seconds.
2	Dormancy	BMS is in the active state. Press the key (3 ~ 6S) and release it, the protection board is dormant, and the LED indicator lights up successively from the lowest power light for 0.5 seconds.
3	Reset	BMS is active. Press the key (6 ~ 10s) and release it, the protection board is reset, and all LED lights are on for 1.5 seconds at the same time.

Explanation

After the BMS is reset, it still retains the parameters and functions set by the upper computer. If it needs to be restored to the initial parameters, it can be realized through the "restore default value" of the upper computer, but the relevant operation records and stored data remain unchanged (such as power, cycle times, protection records, etc.).

5.2.4 Sleep and wake up

Sleep:

When any of the following conditions occurs, the system enters into the low power consumption mode:

◆ Single or overall over discharge protection is not released within 30 seconds.

◆ Press the key (3 \~ 6S) and release the key.

The minimum monomer voltage is lower than the sleep voltage, and the duration reaches the sleep delay time (no communication, no protection, no balance and no current).

◆ The standby time exceeds 24 hours (no communication, no charge and discharge, no mains power).

◆ Forced shutdown by upper computer software.

Notice

To enable forced sleep mode, ensure that the input terminal is not connected to the external voltage, otherwise it will not be able to enter the low power consumption mode.

Wake up:

When the system is in the low power consumption mode and meets any of the following conditions, the system will exit the low power consumption mode and enter into the normal operation mode:

- Connect the charger, and the output voltage of the charger shall be greater than 48V. (the battery voltage of 16 strings needs to be greater than 51.2V)

- Press the key (3 \~ 6S) and release the key.

◆ Activation of RS232 interface.

Notice

After single or overall over discharge protection, enter the low power consumption mode, wake up regularly every 4 hours, and turn on the charge discharge MOS. If it can be charged, it will exit the sleep state and enter normal charging; If the Automatic wake-up fails to charge for 10 consecutive times, it will no longer wake up automatically.

When the system is defined as that the recovery voltage is not reached after 2 days of standby (standby time setting value) after the end of charging, it is forced to resume charging until the end of recharging.

◆ Download Microsoft .Net framework
◆ Double click the downloaded program to install it
This software does not need to be installed independently, but only needs to meet the environment. Double click the main program icon to run it.

6.2 Connect the upper computer

◆ Ensure that the BMS board is normally powered on and not in sleep state, the crystal head of the communication line is inserted into the communication port of the protection board, and the USB end is inserted into the computer.
◆ Double click to start the upper computer.
◆ Click the "try to connect" button to search the serial port to try to connect. Or manually select the serial port and click the "open serial port" button link.

Explanation

If connection fails for the following reasons, the resolutions are:

◆ Using the wrong host computer: Method: replace the correct version of the upper computer.

◆ Poor communication line or wrong wiring: Method: replace the communication line or correct the wrong wiring.
◆ The computer USB interface is not recognized: Method: change a USB interface
- Drive not installed: Method: install the driver corresponding to the communication line.

Method for judging whether the communication line driver has been installed:

◆ Check whether there is a relevant COM port in the "serial port" drop-down of the upper computer. If it is not found, it may not be installed.

7. Maintenance and replacement

◆ Please maintain the equipment when you are familiar with and understand the contents of this manual and have appropriate tools and test devices.
Before carrying out maintenance work, please power down the equipment first, then follow the instructions of the delayed discharge label and wait for the corresponding time to ensure that the equipment has been powered down before operating the equipment.
During maintenance, please try to avoid irrelevant personnel entering the maintenance site, and temporary warning signs or fences must be erected for isolation.
◆ If the equipment fails, please contact your dealer in time.
The equipment can be powered on again only after the fault is handled, otherwise it may cause fault expansion or equipment damage.
Do not open the cover plate without authorization, otherwise there will be a risk of electric shock, and the resulting failure does not belong to the scope of warranty.
◆ Operation and maintenance personnel and professional technicians shall be fully trained in safe use and equipment maintenance, and shall operate with sufficient preventive measures and personal protective equipment.
◆ Battery maintenance shall be performed or supervised by personnel familiar with the battery y and its required precautions.
◆ After the maintenance operation, check immediately to ensure that no tools or other parts are missing in the equipment.

8. Battery storage requirements

When the battery is stored, it shall be placed correctly according to the identification of the packing box, and shall not be placed upside down or on the side.
- When the battery packing box is stacked, it shall meet the stacking requirements on the outer package.
- The battery shall be handled with care, and it is strictly prohibited to damage the battery y.

◆ Storage environment requirements:

a. Ambient temperature: - 10 °C \~ 55°C, recommended storage temperature: 20 ? \~ 30 ?.

b. Relative humidity: 35% RH \~ 85% RH.

c. Dry, ventilated and clean.

d. Avoid contact with corrosive organic solvents, gases and other substances.

e. Avoid direct sunlight.

f. The distance from the heat source shall not be less than two meters.

When the battery y is stored, it must be disconnected from the outside. If there is an indicator on the battery panel, the indicator should be off.
The warehouse keeper shall count the battery storage every month and regularly report the battery inventory to the planning link. For batteries with storage time close to -20 \~ 25°C = 6 months and -20 \~ 45°C = 1 month, replenishment shall be arranged in time. The battery shall be charged once every three months (under the normal storage environment, long-term storage will lead to capacity attenuation and cycle life decline. If it exceeds the storage environment requirements, it will further aggravate the capacity attenuation and cycle life decline.)

When the stored batteries are shipped, the principle of first in first out shall be followed.

◆ Battery maintenance shall be performed or supervised by personnel familiar with the battery and its required precautions.
◆ After the battery production test is completed, it needs to be supplemented to 30-50% SOC at least before storage.
