innolectric to begin series production of the 22kW On-Board Charger

innolectric has completed the development of its 22kW On-Board Charger with silicon carbide technology. The final preparations took place until the end of 2019, before series delivery will start in the 2nd quarter of 2020. Customers will benefit from a system solution from one single source for AC and DC charging with maximum efficiency.

The innolectric On-Board Charger offers both AC and DC charging for electrified vehicles, commercial vehicles and machines. Thanks to integrated charging communication in accordance with all current international standards such as IEC 61851, DIN SPEC 70121 and ISO 15118, the innolectric On-Board Charger can be used safely and flexibly worldwide, even in 50 Hz and 60 Hz network topologies.

The On-Board Charger provides 22kW charging power in AC mode and, as a one-device solution, handles the entire charging management including the necessary communication with the charging infrastructure (EVSE) for AC and DC charging.

Depending on the voltage level of the battery and the application, the innolectric On-Board Charger will be available in two different versions. The OBC42 is designed for a voltage level of 400V (220V – 510V) with an output of up to 22 kW. The charging component achieves a minimum efficiency of over 94% between 2 kW and 22 kW. Maximum efficiency is over 96%.

In addition to the AC charging function with integrated PWM communication at up to 22 kW, the innolectric On-Board Charger also supports the DC charging process with international standard-compliant communication according to DIN SPEC 70121 and ISO 15118. A further variant will be the OBC82, which is designed for a voltage level of 800V (400V – 850V) at a power of 22 kW. The charging power can easily be increased by connecting several innolectric On-Board Chargers in parallel.

As part of the development of the innolectric On-Board Charger, the Bochum-based company is working closely with STMicroelectronics, a leading international manufacturer of embedded components and in the field of silicon carbide technology, in the field of silicon carbide technology.

Tim Karcher, CEO of innolectric AG, emphasised on the start of series production: “After having invested a lot of time, expertise and work in the development of the innolectric On-Board Charger, I am pleased that with the start of series production the supply to our customers now begins. The product is not a compromise, but a solid solution for the commercial vehicle and machine sector thanks to its high efficiency and performance.”
