Water cooling multiplies brake resistor power density

摘要

In the middle of the last decade electric sports, with acceleration comparable to a normal internal combustion engine sports car, began production and there are now a number of very advanced models on the market. They do of course, come with the need for a similarly sophisticated wallet. Cressall Resistors' involvement in the electric vehicle market allowed it to identify the need for the first of a series of Electric Vehicle (EV) resistors, culminating in a product the company christened the EV2. Electric cars have always been at a disadvantage against their petrol-driven counterparts in terms of energy density. A can of petrol weighing 4kg equates to an electric vehicle battery weighing 500kg and costs six Euros compared to 40,000.
