The concept of the energy chain was explained in chapter 1. Essentially, the links in
this energy chain already reflect the basic parts of a BMS. In more general terms, the
charger can be called a Power Module (PM). This PM is capable of charging the
battery, but can also power the load directly. A general BMS consists of a PM, a
battery, a DC/DC converter and a load.
The intelligence in the BMS is included in monitor and control functions. As
described in chapter 1, the monitor functions involve the measurement of, for
example, battery voltage, charger status or load activity. The control functions act on
the charging and discharging of the battery on the basis of these measured variables.
Implementation of these monitor and control functions should ensure optimum use
of the battery and should prevent the risk of any damage being inflicted on the
battery.
The degree of sophistication of the BMS will depend on the functionality of the
monitor and control functions. In general, the higher this functionality, the better
care will be taken of the battery and the longer its life will be. The functionality
depends on several aspects:
