The big four Japanese manufacturers are believed to be working to standardise electric motorcycle batteries and charging infrastructure.
Noted electric vehicle website Electrek says Honda, Yamaha, Kawasaki and Suzuki hope to standardise the technology to prevent any obstacles to its adoption.
No doubt it’s also hoped to avoid the Beta/VHS situation where new video recording technology went two different ways.
Standardised batteries and charging infrastructure would mean plugs on bikes and sockets on charging points would suit all electric motorcycle models.
Perhaps a standardised battery size, shape and output would also lead to a battery swap solution which would be quicker than waiting for a bike to recharge.
So far Japanese motorcycle companies have been much slower to join the electric vehicle revolution than their car compatriots.
Yamaha released the PES1 (Passion Electric Street) road bike and PED1 (Passion Electric Dirt) off-roader for limited sale, mainly in Europe.
Meanwhile, Suzuki has done nothing, at least publicly.
But the fact that they are now collaborating on to standardise electric motorcycle batteries and charging means we may soon have to learn about terms such as volts, amps and kilowatt hours.
Learn electric terms
Living with petrol-powered motorcycles all our lives, we now find we will have to learn a lot of new terms.
We certainly don’t profess to know much about electrical terms.
But here is a very non-technical, idiot’s guide to the main terms. (Electricians may find this quite amusing!)
Volts: This is a measure between two points in an electrical circuit, sort of like the water pressure in pipes. The mains plug in your house has 240V (230V in UK, 110V in USA) and your motorcycle battery has 12V.
Amps: Together with the voltage, it determines the flow rate of the current. High amps with a low voltage means a lot of current flowing slowly, like a fat, lazy river. Low amps with a high voltage means a faster flow of less current, sort of like when you squeeze the end of a hose and the water spurts out.
Watts: It you multiply the volts by the amps you get the watts, which is the output power of the electric motor. You should already be familiar with kilowatts which are 1000 watts. One kilowatt is 75% of one horsepower.
Kilowatt hours: This is the capacity of the battery. Think of how many litres you can fit in your fuel tank. A one watt-hour battery will power a 1W electric motor for one hour. The new Lightning Strike Carbon Edition has a 20kWh battery which means it can produce 1kW of power for 20 hours.
That’s just a start.
There are a lot of other factors involved and other terms for battery energy-density (watt-hours per kilogram), charging terms (AC, DC and fast chargers) and a variety of range calculations that take into regenerative charging.
