PDRM will be conducting a 10,000km test of a bolt-on hybrid system called Revolo in one of its Proton Inspira patrol cars. The evaluation is expected to take about two months time, and the cops will provide feedback on the performance of the system then.
Revolo is a bolt-on hybrid system that's being marketed in Malaysia by DFRAN Technologies Research Sdn Bhd. The executive chairman of the company is none other than the ex-MD of Proton, Datuk Seri Syed Zainal Abidin Syed Mohd Tahir.
If the test run is successful, PDRM may consider fitting the Revolo hybrid system into more of its vehicles. According to Inspector-General of Police Tan Sri Khalid Abu Bakar, PDRM currently has about 3,000 patrol cars in its fleet, with an annual fuel cost of about RM28 million currently.
Revolo originates from India, by a company called KPIT Cummins. It is designed to be used in cars with engine sizes of between 800cc to 3,000cc. A report by Autocar Professional India quotes the cost to be between Rs 65,000 to Rs 150,000, which translates to between RM3,500 to RM8,000 at current exchange rates.
The system consists of an electric motor, electronic motor controller, battery pack, mechanical assemble and coupling, proprietary software for controlling algorithms of the motor and batteries and an intelligent battery management system to enhance battery performance and life. The Revolo system functions in parallel with the engine, which means the engine and motor will work simultaneously.
The system supports regenerative braking for recharging up to 20% capacity, but the battery can also be charged via 220V plug-in and takes three to four hours to get up to 90%, or up to a full charge in six hours. According to Datuk Seri Syed Zainal, the Revolo system's electric motor has a maximum torque of 35Nm, and can provide motor assist of between 80km to 100km on a full charge. Claimed fuel efficiency improvement is about 35%.
