On-Board Charger


On-Board Charger

Efficient power electronics for AC and DC charging

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.


The innolectric On-Board Charger is available in two different variants: OBC42 and OBC82. Thus, the product offers the user great flexibility and future-proofness. Both variants of the On-Board Charger are able to charge with a power of up to 22 kW (AC Charging) and also support charging with high power (DC Charging). Besides the usual AC Charging function via PWM communication, the OBC supports the DC Charging standard PLC (DIN SPEC 70121 and ISO 15118) with an output power depending on the maximum charging capacity of the respective electric vehicle. Users of the innolectric On-Board Charger benefit from a turnkey solution that only requires one integration of the system application on the user side.


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.
