 PCM  ( Protection Circuit Module )
 PCM is  widely applied in rechargeable Lithium-ion and Lithium-polymer and LiFePO4  batteries. Normal voltage of li-ion/li-polymer battery must be within 2.75V  (min) to 4.3V (max.), normal voltage of LiFePO4 battery must be within  2.0V(min) to 3.65V(max.). PCM function is as safety devices during charging and  discharging.
 Major Functions:

  • Overcharge protection

  • Over discharge protection

  • Over current protection

  • Overheat protection(NTC)—can be  selected

  • Short circuit protection

 Lifepo4 battery pack Features
 
 - 10% higher energy density by weight and by volume.
 - Superior safety performance due to patented new safety valve and pressure cap  designs.
 - Safer chemistry minimizes risks of explosion and fire when batteries are  shorted or punctured resulting in internal shorts.

 BMS Information
 Recent development of rechargeable battery technology allowed wider use of  electric propulsion in electric vehicles, electric motorcycles, boats etc. Most  popular high performance batteries are based on Lithium chemistries. Such  batteries require systems to keep them in the specified usage range while being  used. The Battery Management System (BMS) is required for batteries that are  sensitive to their usage conditions such as current, voltage and temperature.  Emus BMS is the product intended for use with LiIon, LiPO, LiFePO4 and other  chemistries prismatic battery cells which operating voltages range is from 2V  to 5V. Emus BMS is a distributed type of digital BMS with central Control Unit.  It does the balancing of the cells by dissipating the excess energy of cells as  heat which is often referred to as passive balancing.

Features and Functionality

Weather protection

Control Unit is hermetically sealed to meet IP55 requirements. Internal electronics protected with conformal silicone coating. Cell Module's electronic parts coated with silicone conformal coating protecting circuits from moisture and dust.

Suitable for different cell sizes

Small size of the cell modules and variable length &bdquo;+&ldquo; terminal wire allows installation on the prismatic cells of different sizes

Tool-less installation

Cell modules can be installed without tools (only a bolt wrench is needed for cell terminals) as cell modules have spring-loaded terminals that allow reliable connection of wires by hand. Pre-cut inter-connection wires are supplied in the shipped package for quicker installation. When connected to Control Unit blinking green LEDs on Cell Modules indicate live communication and allow quick identification of problematic cell connection.

Configurable

BMS has various parameters that are configurable by using convenient Emus BMS Control Panel PC software over USB connection: pre-charge, pre-heat, timeouts, cell voltages (min and max allowed, early balancing threshold, allowed dis balance, etc), currents (maximum balancing current, charge modes), cell parameter read interval,etc...

Configurable balancing current range

Linear zero to max, configurable maximum balancing current – useful to define maximum balancing current and amount of heat dissipated by modules during balancing.

Cell voltage measurement

Real-time bar graph on LCD or PC – useful to detect faulty cells and track battery health, or as general visualization for advanced users.

Cell temperature measurement

Real-time value on LCD and bar graph on PC – useful for controlling charger and load in high temperatures, for setting charging mode and control of battery heater in cold weather (lithium batteries can&lsquo;t be charged below freezing point). Many other BMS systems are not suitable for use in cold environment.

Early cell balancing

Balancing is done while charging, battery pack is in balance when charged – takes no additional time. Many other BMS systems start the balancing only when at least one cell is fully charged and overall charging time is drastically increased (in terms of hours).

Digital one-wire interface between cells

Allows neat and robust installation with lowest count of wires that could break

Forward Error Correction algorithm

Increases data transfer robustness and drastically reduces possibility of faulty data – data is corrected by Control Unit, even if it arrives with errors caused by high EMI levels.

USB interface

USB 2.0 compatible, with free, intuitive and easy to use, good quality Emus BMS Control Panel windows application.

RS-232 interface

Periodically sending the working status and parameters which can be received by LCD display or other device. Parameters output format specification is available upon request.

Simple charger control

Ordinary charger may be conveniently used as BMS detects charger's plug connection to AC mains outlet via optional isolated charger sensing solid state relay. Charger switched on and off via same solid state relay.

Bluetooth adapter (Optional)

Bluetooth adapter for EMUS BMS (allows Tablet PC and smart phones (running on Windows Mobile or Android OS) to be used as Display unit for EMUS BMS, range - up to 10 meters)
