Today, approximately 7 million medium-duty trucks are registered in the US, with around 800,000 new vehicles purchased each year. These vehicles range from shuttle buses, delivery trucks and municipal fleet work trucks. Approximately a third of these vehicles drive planned local routes less than 100 miles a day and park in a depot at night, which is typically wired for high voltage, making them ideal candidates for electrification and onsite charging.
Fleets face many problems pushing them towards alternative fuels, including emissions regulations, oil dependence and price volatility, environmental and growing public opinion on environmental concerns. Fleets are finding solutions to these problems in hybrid and electric trucks, with thousands already on the road, and numbers growing rapidly.
The Motiv electric Powertrain Control System (ePCS) is an “Operating System” which allows truck builders to use a common platform to accommodate different ranges, weight classes, power levels and battery suppliers. This enables electric vehicles to be customized to minimize cost and maximize range with minimal engineering. Essentially it allows the use of any battery and any motor on any chassis using the same hardware, requiring only a minor rewrite of the software. It is similar to the concept of an operating system (OS) in a personal computer (PC) where installing a new peripheral device only requires a new driver.
The Motiv ePCS is a combination of hardware and software. The hardware includes Power Control Unit (PCU) which is similar to the Central Processing Unit (CPU) in a PC and Adapters to the different electrical components – battery packs, motor, charger and auxiliary power. Thus, allowing you to get durable electric vehicles without expensive hardware redesigns just software reprogramming.
