Charging Solutions

Multi-circuit battery charging system with integrated FireCAN
 

This battery charging system is ideal for installation in a vehicle to ensure that the vehicle will be ready for action right away, even when it has been standing for a long time. The Acctiva Twin has two charging circuits, enabling several batteries of different capacities to be charged. Its intelligent electronic system monitors the charging processes, evens out differing charge states when batteries are connected in series and prevents premature failure due to unbalanced charging. The pre-programmed charging characteristic guarantees the correct charging current for the capacity and condition of the battery.

Product information

• Up to 96% energy efficiency

Technical data

Equipment features

Application

When setting up a 24 V vehicle electrical supply from two 12 V batteries connected in series, the Acctiva Twin ensures that different charge statuses are evened out even if different loads are placed on the two batteries by 12 V and 24 V consumers. The Acctiva Twin can also be used with different battery combinations (see graphic).

Options

• FireCAN communication interfaces and a floating contact are used to transfer data between the battery charging system and the vehicle's electronic system; these are active in drive, standby and charge modes. The FireCAN option transmits device status and battery voltage, and can detect the following problems: reverse polarity. short circuit, battery error, charging error. The integrated error memory stores the ten most recently countered errors. More information to FireCAN can be found here.
• The temperature-controlled charging option reduces water consumption and increases battery service life.
• USB interface for updating battery charging system software.
