Kawasaki’s new patent reveals more details about its electric bike

- More details about its cooling set-up revealed

- It will use oil for cooling the electric motor

- It also gets a transmission system

Kawasaki seems to be moving forward with its electric motorcycle plan as newly emerged patents reveal more details about the bike. It was in 2016 that we first reported about Kawasaki's electric bike patents and the emphasis was on the cooling setup of the motor. Now, more details about this cooling system have been revealed by the recently published patents.

Apart from the battery and electric motor layout, the patent bears the description about the oil-cooling setup. As per this description, the powerplant assembly has a passage for taking in the outside air which is channeled to the interior of the battery case. This air, along with the air blown by the in-built radiator fans, is used to cool the oil which acts as the coolant for the electric motor. The resultant effect is efficient cooling for the motor which prevents the heating of the powerplant. 

Interestingly, the patent also reveals that the electric motor is accompanied by a transmission set up, similar to the petrol-powered motorcycles. However, there’s no detailed explanation about the transmission system in the patent. Apart from the electric motor section, many other parts have been represented by dotted lines which means they are likely to change. 

Although there’s no information regarding when this Kawasaki electric bike will be ready for production, the new patents signify such a motorcycle might not be too far.
