The CAN Opener

Many data logging systems for vehicles can be found on the market, from basic systems that only store the on-board communication for later evaluation, to more complex systems with radio-transmission and custom analog/digital measurement options. These systems almost always use the CAN bus communication protocol, which is the industry standard for on-board data communication due[…]

The Stack

Two months ago I wrote about the “stacks” in the battery pack. “Stack” has become often-used jargon within Nova Electric Racing for the building block of the battery pack. It contains a certain amount of battery cells connected in series, the BMS in order to monitor the health of the cells and structural support for the cells to[…]

CAD Model Battery Pack - With Constraints

The Whole Package

As an electrical engineer, I thought that designing a battery pack for the motorcycle would be mainly about its energy capacity, power output, energy losses and electrical protection. Now that was the case for a while, when we were doing simulations to estimate the required capacity and power. Two full weeks were occupied by this[…]

PCB connnection myRIO

On-site Training

In the week before the December holidays we went to the on-site training provided by the Dutch office of National Instruments situated in Woerden. The training was called LabVIEW Real-Time and dived into the real-time processor and the FPGA chip of the myRIO, which I talked about in the previous blog post. Roelof-Jan (Chief Powertrain), Nicolaas and I[…]

Battery pack testing

The High Voltage Fashion

In my previous blog post I talked about the failure that happened during the dynamometer test. It was concluded that a short-circuit in the high-voltage compartment of the bike caused the motor to block. This short-circuit only lasted for a moment, but it was quickly noticed that something was damaged in the battery pack as[…]

The NovaBike07

Safety First

Most issues that occurred to the motorcycle the week before and during the race in Pembrey, Wales were caused by a wrongly executed startup sequence of the bike. This sequence consists of powering on the low-voltage systems, charging up the motor controller in the right order, enabling the subsystems and turning on the cooling system.[…]
