![]() ![]() Operating a battery outside of its specified design limits will inevitably lead to failure of the battery. Power designer battery logger full#In practice the BMS must provide full cell protection to cover almost any eventuality. ![]() Cell Protection Protecting the battery from out of tolerance operating conditions is fundamental to all BMS applications.(Follow the links to see how these functions are implemented.) To achieve these objectives the BMS may incorporate one or more of the following functions. Maintain the battery in a state in which it can fulfil the functional requirements of the application for which it was specified.Protect the cells or the battery from damage.There are three main objectives common to all Battery Management Systems The battery can not simply be treated as a black box. ![]() This requires an in depth understanding of the fundamental cell chemistries, performance characteristics and battery failure modes particularly Lithium battery failures. In order to control battery performance and safety it is necessary to understand what needs to be controlled and why it needs controlling. This includes everything from controlling the charging regime to planned maintenance.įor the automotive engineer the Battery Management System is a component of a much more complex fast acting Energy Management System and must interface with other on board systems such as engine management, climate controls, communications and safety systems. Such systems encompass not only the monitoring and protection of the battery but also methods for keeping it ready to deliver full power when called upon and methods for prolonging its life. The monitoring circuits would normally provide inputs to protection devices which would generate alarms or disconnect the battery from the load or charger should any of the parameters become out of limits.įor the power or plant engineer responsible for standby power who's battery is the last line of defence against a power blackout or a telecommunications network outage BMS means Battery Management Systems. To some it is simply Battery Monitoring, keeping a check on the key operational parameters during charging and discharging such as voltages and currents and the battery internal and ambient temperature.
