MotoE Second Test at Jerez in on its way. Energica further tests the Dry Ice cooling system meant to ensure ideal level of performance with three sessions during the same day.
MotoE Second Test at Jerez in on its way riding with the Energica Ego Corsa Electric track motorcycle. Dominique Aegerter sets the pace on opening day, as the Swiss rider was half a second clear of his rivals. Lukas Tulovic (Tech3 E-Racing) was closest behind and rookie Miquel Pons (LCR E-Team) grabbed an impressive third, a tenth and a bit off.
Reigning Cup winner Jordi Torres (Pons Racing 40) was fastest out in the morning, topping session one of three. But Dominique Aegerter grabbed Session 2 and sealed the deal being the sole rider in the 1:47s, and setting his fastest lap of the day. Tulovic, Pons and fourth overall Eric Granado (One Energy Racing) all set their best times in Session 3, with Torres’ time from Session 2 placing him 5th overall.
Energica, the single manufacturer of the FIM Enel MotoE World Cup, continue their constant R&D to improve the performance of the Ego Corsa machines, and optimize for smooth runs during a three session day in the second test run at JEREZ track.
The MotoE World Cup is entirely ridden on Energica Motors Ego Corsa track variants. These track models produce an extended 120kw from the motor (with 110kw on standard models) and a whopping 200Nm of torque.
In the previous official MotoE test at Jerez de la Frontera in March, Energica brought a new cooling system designed and developed to ensure the ideal level of performance with three sessions in the same day. That was combined with extremely hot weather condition.
Giampiero Testoni, the CTO of Energica, explains in detail how this new system works:
“This idea came from the fact that, during winter testing, we want riders to do as many laps as possible during the three sessions per day. With fast charging and the actual riding on the track, it can happen that in the last session of the day, a situation of power limitation by the bike can be triggered. Therefore, we decided to implement a system with dry ice; we firstly created a test system, and we made some trials with different configurations: different type of systems (open/closed, fan/blower), while simulating battery heating – and keeping track of the temperature. In the end we chose the one that we reckon was more fitting to the situation.
This system is simple: it is basically a thermic box containing dry ice: our Makita blower blows air through a tube into the box, and, with the dry ice, the air temperature decreases considerably an in a very short time. The cold air is then sent out to the bike through another tube and the cooling process begins.
The dry ice cooling system allows the Energica systems to easily reduce heat between runs, which is a great use for simple technology. Dry ice has been used before for actual on-bike cooling, during the land speed record electric motorcycle, the Voxan Wattma. that reached 254mph (408km/h). In that case, the use for a single burst of power, while keeping systems from overheating and reducing performance, proved to pay off. The Italian rider Max Biaggi set a grand total of 11 records for fully streamlined, partly streamlined and standard/ naked categories (for world record land speeds).
