On-Board Charger

Ensuring trouble-free charging of electric vehicles and conformity with international standards is crucial in the market. Both power transmission and charging communication must operate smoothly in order to successfully charge vehicles. Based on these standards, the innolectric On-Board Charger can be used for cars, trucks, commercial and construction vehicles as well as for new mobility concepts.

Thanks to the innovative technology of STMicroelectronics, innolectric offers products such as the On-Board Charger with very high efficiency of more than 96 % and highest quality.

The innolectric On-Board Charger is available in two different versions, each in the 400 V and 800 V design. The product thus provides the user with great flexibility and sustainability. The two designs 400 V (OBC42) and 800 V (OBC82) of the On-Board Charger can charge with a power of up to 22 kW (AC charging) and also support DC charging with significantly higher powers. In addition to the usual AC charging function based on PWM communication, the OBC42.1 and OBC82.1 support the DC charging standard DIN SPEC 70121 (in future also ISO 15118) in which charging communication is implemented on the basis of Power Line Communication (PLC). The possible charging power is only limited by the electric vehicle itself or the available output power. Users of the innolectric On-Board Charger benefit from a turnkey solution where only one component needs to be integrated at system level to realize both AC and DC charging.

• AC charging up to 22 kW with 96 % efficiency
• DC charging functionality integrated
• Charging communication for AC and DC charging is fully integrated and supported without any additional devices
• Compatible with EU & US power grid topologies
• Full interoperability with all standard-compliant charging stations according to IEC 61851, DIN SPEC 70121 and ISO 15118

The OBC|G gives users the option of a power electronic version for AC charging via a direct mains connection. The OBC|G is compatible with a standard 3-phase mains connection (e.g. standard industrial CEE plug) and can be used without any automotive charging communication. This results in the advantage that charging with the OBC|G is possible without any problems independent of an automotive standard compliant charging infrastructure. The limitation of the input current is manually selectable.

To increase the AC charging power, it is possible to use two or more OBC|G in parallel. Each of them is controlled by a separate CAN message to achieve a simple, fast and safe charging topology.

The integration of the OBC|G is simple: Only the available AC Charging power has to be transmitted to the OBC. The OBC|G is connected to the EV CAN and receives current, voltage and charging requests. This makes the version particularly suitable for the industrial environment, e.g. in usage scenarios with temporary charging infrastructure. With the AC/DC Converter, the innolectric portfolio offers another practical solution in the field of charging technology, for example as a basis for setting up a charging station.

• Parallel charging mode enables flexible increase of charging power
• Easy integration into an existing infrastructure without high integration effort
• Can be used for stationary connection, for example in marine or industrial applications, and enables safe and flexible integration
• Can be used with direct mains connection without any charging communication for AC charging
• Compatible with EU and US grid topologies
