Enevate drops electric bike hurdle

Electric motorcycles could soon recharge to 75% capacity in as little as five minutes, according to Californian battery company, Enevate.

Company spokesman Bill Blanning tells us they are “talking to motorcycle and scooter makers worldwide” about their Li-ion batteries that use silicon-dominant anodes. 

“We are not ready to disclose that just yet. Stay tuned,” he says … and we will!

“Electric motorcycles can do very fast charging at EV DC fast-charging stations.

“We believe that cooling systems would need to be beefed up and feasible for extreme fast charging of motorcycles while parked.”

Enevate claims

The Californian company has more than 200 patents worldwide and licences its products to many automotive manufacturers.

Here are their claims about their battery:

  • 30% more range, higher energy density;
  • >100% better low temperature performance;
  • Safer battery with no lithium plating.
  • Enables lower cost and affordable EVs
  • 10-times faster charging; and
  • 5-minute Extreme Fast Charge.

The best way to show their charging and range claims in action is in this video using two slot cars.

Given the claimed 30% increased range, in Harley-Davidson’ electric LiveWire it would equate to range of more than 300km in the city and almost 200km on the highway.

Low temperature performance means you would be less likely to get stranded if riding up in the alps.

While Enevate doesn’t give any secrets away about how it is made, the fact that it uses less lithium is another safety, economic, environmental and humanitarian benefit.

Bill explains: “Li-ion cell safety issues are typically caused by contamination or lithium-plating.  For today’s conventional graphite Li-ion cells available, lithium plating typically happens at very high charge rates and/or charging at low temperatures.  Enevate’s technology does not have any lithium plating and can be safer than conventional graphite cells.”Enevate batteries

The company says the size and expense of batteries is a hurdle to widespread adoption of electric vehicles.

It’s also a particular hindrance to motorcycles which weigh less and usually cost a lot less than cars.

However, we have seen electric motorcycles at ridiculous prices. For example, the LiveWire costs almost $US30,000 in the US and could cost more than $A40,000 when it is launched here late this year.

Enevate say their batteries have much higher energy density which means they can be smaller and therefore a lower cost component of the whole vehicle cost.

Their claim that recharging will be 10 times faster means that electric motorcycles such as the LiveWire that take all night to recharge from a standard AC output could recharge in less than an hour.

If the rider has access to a DC fast charger, that time can drop to about five minutes with the Enevate battery which compares with Harley’s claim of 30 minutes for the LIveWire.

The big hurdle in Australia is our lack of such infrastructure, but it is gradually being installed across the nation’s highways.

Enevate isn’t the only company claiming faster recharge times.

Canadian company GBatteries are making the same claim with their batteries that use a special micro-pulse technology.

Suzuki slow to plug into electric revolution

Suzuki has been slow to plug into the electric motorcycle revolution, but looks like finally joining the other Japanese motorcycle manufacturers, at least in the Asian market.

The big four Japanese manufacturers have all been slow in announcing their intentions with electric motorcycles and scooters.

However, in April 2019, electric vehicle website Electrek claimed Honda, Yamaha, Kawasaki and Suzuki has signed an agreement to work on standardising electric motorcycle batteries and charging infrastructure.

No doubt it’s 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.

Slow revolution

By comparison with their major counterparts, the usually innovative Japanese motorcycle companies have been slow to join the electric vehicle revolution.

Yamaha released the PES1 (Passion Electric Street) road bike and PED1 (Passion Electric Dirt) off-roader for limited sale, mainly in Europe.

Kawasaki has filed a patent for a water-cooled electric.

Honda has a hybrid scooter and an electric self-balancing prototype.

Meanwhile, Suzuki has been the slow coach with no patents, no announcements, nothing!

Until now.

Autocar India reports that Suzuki Motorcycle India MD Koichiro Hirao says they are working on an EV platform for India.

There is no word on what that EV platform will be; motorcycle, scooter, mobility scooter!

Nor is there any word about whether they would be available outside the country.

India is becoming a major player in the EV market with a host of companies from start-ups to major manufacturers now making them.

This comes in the wake of tough new emissions regulations in the overcrowded and polluted country.

Learn electric terms

Living with petrol-powered motorcycles all our lives, we now find we will have to learn a lot of new terms in the coming electric revolution.

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 1.34% of one horsepower or one horsepower is 0.75% of a kilowatt.

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.
