Battery configurator


Vehicles fitted with Idle Stop Start (ISS) systems have been developed by manufacturers to improve fuel efficiency and reduce carbon emissions, in line with global emissions targets.  

With the introduction of such CO2 production control systems, it is essential that the vehicle has the correct battery type and specification installed.  More importantly a number of automotive manufacturers have introduced active energy management systems that require the replacement battery to be correctly configured to the vehicle after installation.

These energy management systems control the charging system, to ensure optimum battery performance and Stop Start system functionality. The system uses information from the battery monitoring sensor to measure the battery’s Current, Voltage and Temperature. This data is used to calculate the battery’s state of health and state of charge.  The energy management system then adapts the battery charging strategy to manage electrical loads.

Failure to configure the correct specification battery could result in:

  • Undercharging or overcharging of the battery resulting in premature failure
  • Potential damage to the vehicles electrical system
  • Loss of Idle Stop Start system functionality
  • Increased CO2 emissions & fuel consumption
  • Possible loss of non-critical vehicle functions


Configuration of the active energy management system can now be carried out using the Yuasa Yu-Fit battery configurator.

The Yu-Fit configures the replacement battery to the active energy management system and battery monitoring sensor.  It informs the vehicle a new battery has been installed, of the correct technology and performance. It will also inform the charging system of the new battery characteristics and ensures the correct charging strategy is applied.
