Open Class- motor number, battery capacity, recharging...

Kia ora WGP

Thanks for your questions.

1. If we are competing in the 1000W category do we change the amount of/ strength of motor or the amount of batteries or strength?

The Open Class was designed to accommodate teams that did not want to use the standard motor and battery kit provided. In this class the total maximum output power of the motor(s) is not to exceed 1kW. You can have multiple motors. You will require battery capacity sufficient to provide enough current to the motor(s) at full power, this is otherwise known as current draw and may be measured in Amps. You will also need to supply that over the expected run time for the events you're competing in, this may be measured in A/h. There are several variables that could affect what you ultimately need (for example the max current draw may only be required for a very short time) so you should research this thoroughly. There will be a balance required between physical size and mass of batteries vs power requirements. As stated in the design guide, battery voltage is not permitted to exceed 48v.

2. We have an idea that we want to have innovative ideas that are detachable, or does everything have to be built to the kart?

Any detachable items need to be presented to scrutineers and their attachment/ removal demonstrated so the effect on competitor and spectator safety can be assessed. We need more details on specifics, as safety critical components are not to be detached! It is the teams responsibility to bring detachable items to the attention of the scrutineers. What were you thinking of?

3. What are the restrictions for competing in the event (weight/ materials allowed to use, etc.)?
Please refer to the design guide and technical regulations on www.evolocity.co.nz. There are no weight restrictions, lighter is better for the efficiency of Electric vehicles. There are no limitations on material used as long as they are up to the task of keeping the competitors and spectators safe. If you have concerns, come back to us before committing to your build.

4. Can we recharge our batteries after each race, also what is the amount of charge (hours approx)?
No. The events are designed to be done on a full charge, managing battery life through the day is part of the challenge! Do you want to know the specifications for the standard battery.

5. Can we have a picture of the electrical/ motor system that was handed out on the AUT Build day?
The standard kit is pictured in the flyer document on evolocity.co.nz/wp-content/uploads/2017/03/Schools-flyer-GENERIC-2017-1.pdf from the www.evolocity.co.nz website

6. Lastly can we have information on the 2017 event?
Also on the flyer.

Hope that helps, re post any areas you/ we want further clarification. For example the removable items.
