Flywheel Fast Charging Station for Electric Vehicles

Gyrotricity正在帮助解决英格兰公路公司面临的挑战，即如何加强其战略公路网上的当地电力网络，以应对未来因电动汽车(EV)充电而增加的需求，而不会产生过高的成本。这是一个全国性的问题。英国下议院最近的一份报告估计，为应对交通电气化而加强英国的电力网络可能耗资高达160亿GB。由于无法准确预测电动汽车的使用率，因此很难规划当地电网的加固。随着快速充电变得越来越普遍，这个问题变得更加尖锐。今天需要7或22千瓦交流功率充电的车辆将逐渐加入需要150-400千瓦直流功率的车辆的行列。由于没有人能预测这一切何时会发生，因此根据需要，以低成本和模块化的方式加强快速充电站附近的当地电力网络将是可取的。Gyrotricity将直接解决这一问题。使用飞轮，即“动能存储”，专门解决超快的能量转移，以补充电网、电池等提供的基本负载能量。它们安装在电动汽车充电站附近的前院，在没有需求时缓慢充电，然后以比电池更低的成本将这些能量高速倾倒到电动汽车中，并且没有热问题、没有火灾风险、非常长的寿命和易于回收利用。实际上，飞轮缓冲了高峰值电力需求，使电网不必提供突如其来的电力峰值，从而招致高昂的资本和运营成本。Gyrotrity正在开发突破性的飞轮性能，以解决传统的安全、成本和功率损失问题。Gyrotricity与英国多所大学的卓越研究中心合作，确保英国现有的最好技术将用于世界领先的产品，满足道路电气化和电力管理的下一阶段需求。

Gyrotricity is helping to address Highways England's challenge of how to reinforce the local electricity network on their Strategic Road Network to cope with increased future demand from electric vehicle (EV) charging without excessive cost. This is a nationwide problem. A recent House of Commons report estimated enhancements to the UK's electricity network to cope with the electrification of transport could cost up to £16 billion.Planning for local electricity network reinforcement is difficult because the rate of uptake of EVs cannot be accurately forecast. The problem becomes more acute as fast charging becomes more common. Vehicles that today require 7 or 22kW of AC power to charge will gradually be joined by vehicles that require 150 - 400kW DC. Because no one can predict when all this will happen, a low cost and modular way to reinforce local electricity networks near fast charging stations, as needed, will be desirable. Gyrotricity will directly address this problem.The use of flywheels, or 'kinetic energy storage,' specifically addresses super-fast energy transfer to compliment base load energy supplied by the grid, batteries, etc. Installed on forecourts near EV charging points, they build charge slowly when there is no demand and then dump that energy at high speed into an EV at a lower cost than batteries and with no thermal problems, no fire risk, very long life and easy recyclability. In effect, flywheels buffer high peak electricity demand and unburden the grid from having to provide sudden power peaks that incur both high capital and operating costs.Gyrotricity is developing breakthrough flywheel performance that addresses traditional safety, cost and power loss issues. Working with centres of research excellence at a number of UK universities, Gyrotricity is ensuring that the best technology available in the UK will go into a world leading product that addresses the next phase of roading electrification and power management.
