Battery Monitor Device
The battery inspection device is a detector which composed of high-speed MCU control circuit boards, isolation amplifier, LCD, case, terminal blocks, etc. Characteristics are simple technology, stable performance, low cost, simple operation.
MCU makes cycle measure for battery voltage and temperature, through high-speed calculation, it can figure out the voltage and status of battery which showed by LCD display.
Principle of the Battery monitoring device
MCU calculated the sampling battery voltage and temperature, send out LED status display and LCD data and status display.
Through scanning the operation button (flip screen button), MCU sends the displaying battery information used to check.
Product outside view
Status of LED indication:
battery over-voltage indicator--indication of battery voltage is higher than protect voltage.
battery low-voltage indicator--indication of battery voltage is lower than protect voltage.
battery normal indicator--all battery are in normal status.
flip screen query button--query every battery voltage and status and failure information.
fixed installation of battery monitoring device
Outside size: 190×152×57
Case size: 160×152
Install pitch: 175×85
1. Installation of external type
Fix the bottom install hole of battery monitoring device to case’s surface, as pic 3-2 shows.
2. Installation of internal type
Fix the top install hole of battery monitoring device to case inside, and open a monitor hole in case surface, as pic 3-3 shows
Pic 3-3 installation of internal type
The connection of power cord.
The connection of single unit battery sampling wire
following use the connection wire of 4pcs batteries as sample:
Display and status
LCD shows the first screen as company name:
LCD shows the second screen as failure battery quantity:
LCD shows the third screen as serial number of failure battery:
LCD shows the fourth and fifth screen as temperature:
LCD shows the battery voltage and status after the fifth screen, every screen shows two batteries information:
When there is flip screen in 3-4minutes, the backlight of LCD will shut down automatically, to reduce the consumption of power.
The backlight will lighten again when flip the screen by manual or appear failure .
1. Failure of battery pcs only shows 5pcs battery series number.
2. Temperature shows only 2 screen, and with 4 temperature value.
3. Voltage shows the A decimal places.
