Product Details

Product: Deligreencs Lithium Battery Management 400A Smart BMS with CAN Module Bluetooth Module Uart Cable

(For 3.2V rated LiFePO4 battery pack only)

Advantage

◆ Use top quality (A-level) protective integrated circuit IC, from the solution of Seiko of Japan. IC itself has power balancing function. The circuit is simple and reliable.

◆ Strong load ability, constant discharge current 100A 120A 200A 250A, , use high voltage resistance, low inner resistance power Mosfet. The heat sink will greatly help cooling.

◆ Typical voltage detection for each cell. So each battery will be prevented over charged or over discharged. Over current and short circuit protection function is very reliable.Long time short circuit of the load won’t affect the PCB and the battery.Temperature protection during charging and discharging.

◆ Extreme low power consumption. The consumption of the whole device is less than 50uA.

◆ PCB use high anti-corrosion, high water resistance, high impedance ESD conformal Coating.

Feature

◆ UART : It is Daly normal product. UART is Universal Asynchronous Receiver/Transmitter, It transforms the data to be transmitted between serial communication and parallel communication. As a chip to convert parallel input signals into serial output signals, UART is usually integrated into other communication interfaces.

◆ RS485: Please choose the model RS485 of Daly. RS-485 adopts balanced transmission and differential reception, so it has the ability to suppress common mode interference.

◆ Bluetooth module : if you need this function, Please choose bluetooth module, if you do not buy it, we will not send it to you.

◆ Below accessary need you to buy separately.

1. USB to UART Cable

2. USB to RS485 Cable

3. Bluetooth module

4. Power display panel (key activation)

5. BMS touch control screen

6. LCD touch screen

Bluetooth module	choose by customer
UART to USB cable	choose by customer
485 to USB cable	choose by customer
CAN to USB module	choose by customer
Power indicator	choose by customer
LCD touch screen	choose by customer

Attention: Customer need to identify the battery's series, then choose the same series BMS. Such as your battery is 24S, you must choose 24S BMS, can not choose 20 or other one. The number of series of BMS is fixed ,not adjustable once the BMS is shipped out .

◆ Control instructions: remote control device monitoring.

◆ Vehicle icon: data transmission send command

◆ Statistical report: Collect the data information, the customer can monitor the battery capacity & other alarm infomation.

◆ Electronic fence: fence setting limit range.

◆ Device information: device parameter information, etc.
