in-tech smart charging GmbH, a 100% subsidiary
of in-tech GmbH, announces that the new automotive control unit Charge Control
L has been successfully integrated into an e-bus of e-troFit GmbH as part of an
upgrade project. The company has thus for the first time installed a
functionally safe and real-time capable control unit for fast charging with
direct current (DC) in one of its buses. In the future, other vehicles in the
fleet will also be equipped with the new controllers.
As the world's first digital OEM, e-troFit
GmbH offers innovative solutions for the electrification of used and new
commercial vehicles. With e-troFit's technologically leading retrofit kits,
conventional diesel buses are given a second life as environmentally friendly
electric vehicles - according to the highest international standards for
functional safety in the automotive industry. With its electrification kits,
e-troFit delivers not only a high-quality, but overall, the most efficient
mobility solution currently available for achieving the Clean Vehicles
Directive, which will come into force in August 2021. Fleet operators thus
benefit from a long-term, economical, and sustainable control tool for
designing an emission-free vehicle fleet.
Control unit with fast-charging function
In order to be able to fully recharge the
batteries of its electrified vehicles as efficiently as possible and in just a
few hours, e-troFit was looking for a real-time capable control unit for fast
charging. The Charge Control L from in-tech smart charging convinced the team
and was used for the first time in an e-troFit bus as part of a pilot project
in April 2021.
Standarized and safe operation
The process: the control unit is
integrated into the vehicle by means of a CAN interface and handles
communication with the charging station and monitoring of the charging process.
In addition, the control unit can be connected to an onboard charger to enable
AC charging and to extend older architectures with ISO 15118 functionalities.
Charge Control L complies with ISO15118 or DIN70121 charging standards for DC
charging and IEC61851 and ISO15118 for AC charging. It was developed in
accordance with the automotive standard ISO 26262 and meets the required safety
standard ASIL B. To this end, the control unit also monitors the temperature at
the charging plug, the status LEDs and the plug interlocks.
Start of series production in early 2022
"With our control unit, an E-bus is fully recharged in 2.5 to 3
hours. The product met all the requirements of e-troFit GmbH, so we started
with a pre-series status. The plan is to install the control unit as standard
at the beginning of 2022," explains Thomas Wagner, CEO of in-tech smart
chargebyte supplies hardware and software products for all aspects of charging communication. With more than 10 years of experience in the field of powerline communication, the company offers solutions for the charging function in electric vehicles as well as in charging stations. The award-winning products rely on forward-looking technologies such as Vehicle-2-Grid, which turns vehicles into temporary energy storage devices. The products are developed and manufactured in Germany and are used worldwide.
