====== Robotina Battery Management System ======



===== General description =====

This system comprehensively measures the battery performance, and displays the real-time parameters and real-time alarm for the 
failed battery to realize the automation of battery detection and failure expected detection. 
Through real-time monitoring of the battery power parameters and operating status obtained by the Controller, 
the actual operating status and health status of the battery pack can be accurately grasped, and problems existing in the use of the battery pack can be found in time.
The HMI touch display  displays the power data, health status and alarm reminder of each battery in real time. 
The cell sensors detects the condition of each battery in real time, and gives a timely alarm to the bad battery, 
so as to accurately grasp the actual running state and health of the battery pack in real time, and to timely find problems in the use of the battery pack. 
This not only effectively extends the backup time and operating life of the battery pack, 
but also greatly reduces the maintenance costs such as manpower and material resources. 
It also improves the safety of battery use, reduces the accident rate and effectively saves energy and reduces emissions, 
creating for the user and create good economic and social benefits for the users.
