ECM monitors driving style and selects a suitable time to employ
regeneration. Regeneration continues until ECM calculates that all the soot
has been burned. But sometimes the required long journey motorway-type
trip necessary to complete a passive regeneration of the DPF system is not
attained, the regeneration fails. So manufacturers have had to adapt the
technology and design an “active” regeneration process controlled by the
ECM.
Active Regeneration
When the diesel particulate (soot) loading in the DPF reaches a pre-set limit
(normally around 45%), the ECU will make minor adjustments to the fuel
injection timing system which will in turn increase the exhaust temperatures
and help initiate the DPF regeneration process. This is a smart way of
getting a motorway-type temperature to build up inside the DPF system and
begin a full regeneration to bring the unit back to good health.
BMS
The battery management system (BMS) is a critical electronic system of
vehicle that monitors and manages a rechargeable battery. The purpose of
the BMS is to guarantee safe and reliable battery operation by monitoring
and evaluating the battery states, including state of charge, state of health,
and state of life, controlling the charging and discharging of the battery,
balancing the cell etc. As an electrochemical product, a battery acts
differently under different operational and environmental conditions.
