BMS &PCM

The Battery Management System (BMS) functions as the “brain” of the battery pack. It measures and reports crucial information for the operation of the battery at the cell & pack level; monitoring state of charge, state of health, protection and wide range of operating parameters.  

 

In its simplest form, a BMS is a Protection Control Module (PCM).  A PCM is normally embedded in the battery or battery pack and prevents cells from over-charging and over-discharging conditions. 

 

Battery protection circuits have two electronic switches known as MOSFET’s or semiconductors used to switch electronic signals on or off in a circuit.

 

Battery fuel (gas) gauge ICs measure battery current, voltage and temperature to find state-of-charge and more. These parameters help control a battery pack performance on the system level to ensure efficient functionality. 

 

Overwhelming increases of portable end-user applications in wireless, computing, consumer, medical, industrial, and automotive markets make battery management solutions vital for today’s markets. This demand for greater reliability from battery-powered systems, MicaPowerhelps ensure the highest product safety through implementation of chargers that protect batteries in every operating condition.

 

The Battery Management System is a piece of hardware with an electronic system on board that manages a rechargeable battery (cell or pack) and is the link between the battery and it’s user. Our BMS includes a control module, a display module, a wireless communication module, and an acquisition module for recording the battery's history. 

 

The acquisition module is connected with the input end of the BMS battery management system; and the output end of the BMS battery management system is connected with the input end of the control module; the control module is respectively connected to the battery pack and the electrical device; and the BMS battery management system is connected to the Server-side through the wireless communication module.Along with the BATTERY MANAGEMENT SYSTEM evolving, more and more functions suitable for this industry will be added gradually

Featured Work

 

BMS

 

There are some shortcomings for rechargeable batteries, such as low rate of power storage, short life cycles, series or parallel circuits, safety, difficulty in estimating battery power, etc. Furthermore the various characteristics of batteries are also very different. BMS system, commonly known as Battery Manager, can more intelligently manage and maintain each cell, improve battery utilization, prevent battery overcharge and discharge, pro-long battery life, and monitor battery status.
