4. ADVANCED FEATURES

Besides the general functionality described in chapter 3, the BMV-501
offers additional advanced features too. These features are reviewed in
the next three chapters.
4.1

Historic data

The BMV-501 is able to store special events as historic data in it's
memory. The following events are stored as historic data :
H01 : The charge-efficiency-factor (CEF) automatically calculated.
H02 : The average discharge. This value will be recalculated after
each synchronization.
H03 : The deepest discharge in Ah.
H04 : Number of charge/discharge cycles.
H05 : The number of 'equalizations'. This is the number of times the
battery is fully charged meeting the charged-parameters
condition.
H06 : The number of full discharges (reaching a state-of-charge of
0.0%).
H07 : The number of undervoltage alarms.
H08 : The number of overvoltage alarms.
H09 : reserved
H10 : reserved
The information stated above can be recalled in the 'history readout'.
This readout can be activated by pressing all three keys of the BMV-501
for five seconds. After this five seconds, a flashing 'H01' shall appear on
the display. With the < and > selection keys the value of H01 can be
displayed. By pressing the SETUP (next) key the next history event, in
this case 'H02', can be selected. To jump back to normal operating
mode, all three BMV-501 keys must be pressed for five seconds again.

PC-link

Each BMV-501 offers the possibility to communicate with a Personal
Computer. However, the optional external communications interface kit is
required for this feature. This communications interface only needs to be
connected when actually communicating with the BMV-501, to avoid
unnecessary power consumption. With the dedicated BMV-501 Windows
