Water Cooled 4000 W Electric Skateboard - Part 1

Part one of my 4000 W Electric Skateboard series. A series in which I create a high-power, high-speed electric skateboard, from a high-power 1/5 scale RC car motor, and a very large lithium ion battery. Performance Top speed: 55 Km/h (34 Mph) Power: ~4000 W (5.4 HP) Climbing: The board will climb 30 degree gradients before losing traction. Battery Size: 647 Wh Range: ~64 km (40 Miles) Parts List https://docs.google.com/spreadsheets/... While the board is quite affordable, it does come with some drawbacks, listed below, which became more apparent after extended use: • The battery, while providing excellent range, is physically large, and quite heavy. • Due to the windings of the motor, it requires a lot of phase current to operate, which generates a lot of heat in the VESC, requiring the VESC to be liquid cooled, which while visually interesting, complicates the design. • The use of a boost converter to charge the battery from a 12 V source generates excess heat within the casing, an external charger would have been a better option. • Due to board being one-wheel drive, and very powerful, accelerating and decelerating cause the board to steer quite a bit, making it hard to control.
