Remote Monitoring of Lead-Acid Battery for Electric Forklift Based on WLAN

Lead-acid battery is widely utilized to provide electricity in vehicle. There are dozens of system is used the lead-acid battery for power supply e.g., in electric car, mobile robot, electric forklift, etc. Nevertheless, overuse could significantly effect on life time of battery. In this paper, remote monitoring of lead-acid battery for electric forklift is proposed. We develop a data acquisition system to monitor battery parameters by developing dedicated hardware and software. Inter-integrated circuit (i2c), Analog to digital converter (ADC) and Universal Asynchronous Receiver/Transmitter (UART) are used as the protocol communication. The wireless local area network (WLAN) is used as the backbone networks. In experimental result, the data are successfully send from microcontroller to server. Furthermore, data is displayed on server monitor and stored in database storage.
