BDU... or How to Make a Battery Intelligent

Paris (ots/PRNewswire)

The BDU (Battery Disconnect Unit),
designed by Valeo, is a genuine off switch for the vehicle's
electrical system. It protects the battery against unexpected
discharge, and disconnects it immediately in the event of a short
circuit or accident.
Statistics from breakdown and recovery services show that battery
problems are one of the main causes of breakdowns. This situation may
soon be rectified by installing the BDU (Battery Disconnect Unit), a
small unit designed by Valeo. Installed in series on the battery's
positive terminal to replace the traditional fuse box, it comprises
an autonomous electronic control unit (ECU) designed to enhance the
reliability and state of health of the vehicle's electrical system.
Optimized safety
At the heart of the system lies an electrical intensity sensor and
a relay with a strong cutting capacity, capable of connecting and
disconnecting the battery up to a charge of 1,500 amps.
In the event of a serious accident (causing the airbags to
deploy), the potential risk due to a damaged electrical system is
virtually nil. A signal sent by the shock detector is transmitted to
the BDU, which disconnects the battery automatically - in less than
five milliseconds.
The BDU's disconnection capacity also offers automatic protection
to the vehicle's electrical network, for example in the event of a
polarity reversal.
Increased lifetime for the battery
In addition to the features described above, the BDU offers a
significant advantage to both automakers and end-users: the
possibility of simple, accessible manual disconnection. This protects
the battery from electrical discharges when the vehicle is left
stationary - or in storage - for long periods. The battery keeps its
charge, thereby ensuring a trouble-free return to the road. This
system also helps lengthen the battery's lifetime, by avoiding major
discharges.
The BDU system, which offers advantages both to automakers and
their customers (improvement of the vehicle's reliability and the
safety of its occupants, optimization of the battery's lifetime) will
equip a Europeen vehicle scheduled to go into production in 2007.
