BTCC HYBRID SYSTEM
Combining our current range of performance electronics with a suite of new products, we were entrusted with developing and delivering a brand-new hybrid system for the BTCC, taking the motorsport series into an exciting future.
COSWORTH ANTARES 8 VCU
Our Antares 8 VCU (Vehicle Control Unit) has the capabilities to drive the entire hybrid package, from running the ICE to managing the control strategies for all the hybrid powertrain components. On top of this, Antares 8 facilitates full chassis and ICE data logging. Powertrain strategies can be written using an array of pre-existing software and provide control for: FBW and ICE strategies | Energy deployment | Energy regeneration | Cooling systems | Safety parameter protocols
BATTERY PACK & CHARGING SYSTEM
The 48V battery pack is our advanced energy store for the hybrid system. It includes a 12V charging connection and BMS (Battery Management System). The package is self-isolating on disconnection from the car and when the vehicle charger is disconnected.
The Delta Cosworth BMS monitors battery cell health and the energy control for deployment and regeneration. It also has the responsibility for sending and receiving of all battery related data. Lastly, it manages the control strategies sent from the Antares 8 VCU, these strategies are calculated as a result of the data received from the BMS itself.
ELECTRIC MOTOR
The P2 off-axis electric motor (known as the MGU) is connected to the powertrain through the championships spec gearbox and is used to deploy and regenerate energy stored in the battery pack. The unit is managed by a dedicated motor controller package and is capable of producing 30kW (≈40hp) of peak power.
INVERTER & MOTOR CONTROLLER
The dedicated motor controller communicates the energy and regeneration strategies to and from the electric motor. The unit also manages the energy flow to and from the battery pack. Deployment and regeneration are controlled by the Antares 8 VCU, including motor speed, torque monitoring and energy deployment from the electric motor.

COOLING SYSTEM
We provide custom designed PWR cooling systems for both battery and motor to ensure they are kept within the correct operating temperature parameters. The custom radiators dedicated to the hybrid system components manage cooling for: MGU (Motor Generator Unit) | Inverter/Motor controller | Battery pack |
Temperature sensors and coolant pressure pumps report back to the Antares 8 VCU. In turn, control strategies are communicated to electric coolant pumps to safely manage system temperatures and pressures.

COLLABORATING WITH
To celebrate this year’s #INWED22, we took the time to speak with two of our PDR validation engineers, Bianca and Swati. They spoke to us about their routes into #engineering and the challenges that they faced along the way. https://www.cosworth.com/news/international-women-in-engineering-day-2022/
Our CTO, Chris Crespi attended the @FinancialTimes, Future of the Car #conference last month. He attended all four days of the #event to get a full insight into the #future of our industry.
