Power Management Design Scheme in Electric Motorcycle

Imagine this: On a sunny summer day, you are riding a motorcycle on a high-speed road, the sun is shining on your face, and your hair is flying in the wind. When people think of motorcycles, a lot of people will have such a picture in their minds, instead of immediately thinking about how innovative motorcycles are, especially racing.Brammo Motorsports is a leading electric vehicle technology company headquartered in Oregon, USA. The company has been at the forefront of high-power battery innovation. Brammo has always been committed to the design and development of electric vehicles, including the award-winning Enertia and Empulse. They are actually building some of the highest performance electric motorcycles that are more environmentally friendly than gasoline-powered motorcycles.Battery management technology will continue to improve the way companies use high-power batteries for innovative designs. Today, high-power batteries have been widely used in everything from power tools and vacuum cleaner robots to forklifts and grid energy storage systems.

Brammo's high-end model Empulse R is a street car electric motorcycle with track control racing pedigree. Its Parker GVM motor can provide precise torque and speed, supporting 54hp/6,000rpm output power and 66lb-ft torque. Empulse R has a top speed of more than 100mph and was described by reviewers as "has exactly the same interventional performance as internal combustion engine models, and it also adds a driving feel that will never be achieved by internal combustion engine models."The power source of the transmission system is the Brammo Power BPM1590 battery pack. This 10kWh high-capacity lithium-ion battery can achieve 77 miles of cruising range under comprehensive urban and highway conditions. Its nickel-manganese-cobalt oxide battery can guarantee at least 1,500 charging cycles and can be fully charged in 4 hours. The core of BPM1590 adopts TI's latest battery management IC, which can not only continuously monitor the key parameters of the battery (voltage, current and temperature), but also stop charging and discharging when necessary, thus ensuring a safe customer experience.

The patented Impedance Track battery monitoring algorithm in the battery management circuit can not only monitor the amount of energy added and consumed by the battery cell, but also calculate factors such as temperature and battery aging, so that the remaining mileage can be accurately reported. Our cell balance technology can keep all independent units in the battery always at the same power level, ensuring that a certain unit will not have a weaker power than other units after a period of time, thereby maximizing the life of the motorcycle. All this will bring a pleasant, exciting and highly reliable driving experience to the end user.
