ESCORPIO - ELECTRONICS

BMS and battery pack

Escorpio is an electric vehicle, the electricity needed to power the engine is supplied by a lithium polymer battery (No. 4 LiPo pack 3S1P-3000mAh, for a total of 44.4V, home-made assembly). These accumulators are extremely efficient, have an excellent weight-to-power ratio, but must not be stressed electrically, otherwise the cells themselves will break down and there's even the risk of fire. The Battery Management System (BMS) is therefore essential to ensure that the battery works properly and in complete safety: BMS is designed and manufactured by us (hardware & software) except for an acquisition and balancing card kindly supplied to us by a "technical" sponsor (Linear Technology)

Auxiliary Board

The auxiliary board provides a hub for the CAN BUS used in the machine; on the board there is also a Traco Power that generates the 5V used in some parts of the electrical system.

It is a board that is used to transform the electrical quantities coming from the driver / controller into smaller electrical quantitiesIt is a board that is used to transform the electrical quantities coming from the driver / controller into smaller electrical quantities.
Motor Driver (2019 version)

 

DC MOTOR [12] is driven by MOTOR DRIVER & CONTROLLER circuit [11], which is connected to the MAIN BOARD POWER
OUTLET through the MOTOR JOULEMETER [10]. MOTOR DRIVER & CONTROLLER [11] regulates the amount of electric energy to
the motor. According to the 2019 rules a spring-loaded throttle / dead man switch [18] is connected to the MOTOR DRIVER &
CONTROLLER [11] and when it is released the flow of energy from the battery to the motor is interrupted instantaneou

For several years now Team Zero C has been developing its own home-made drivers: thanks to this we could experiment with different configurations, solutions and devices designed to obtain very high efficiency and zero waste when the driving force is not necessary (vehicle sliding with engine not powered). We currently use a modular configuration, with a μC controller card, and an easily interchangeable power-modules (in case of failure)

 

(measured efficiency: 98.4%)

Dashboard

From 2015 the vehicle is equipped with CAN-BUS, Data Logging & Smart Dashboard: a data communication system that uses the same protocol as commercial vehicles, and an "intelligent" dashboard, where data is collected and stored locally (SD card), equipped with a large and visible TFT-touch display of about 5", and a Bluetooth interface that can connect to the onboard Smartphone to send data to the outside (telemetry).

Telemetry

Als the work of Team Zero C has been articulated on the telemetry for over at least three years: thanks to an important synergy with informatics students, since 2016 Escorpio has an efficient telemetric system that, in real-time by having a smartphone (with the appropriate APP installed) on board of the vehicle, allows us the remote viewing of the parameters of the prototype operation, its position on the track, as well as the vocal communication with the pilot. All of this is very useful for making any strategy corrections.

Motor Driver (2015 version)

Current: 6A (8A)

Voltage: 24 / 38 V

Electronic control system: it is a PWM driver that has the task of controlling the power that reaches the motor. The pilot has a control knob, similar to a gas of a scooter. The circuit has been developed and carried out entirely in 'ITIS Vinci’ high school.

London 2019: 3rd place in the battery electric prototypes category.
