Specific energy, the flywheel battery is larger than the nickel-metal hydride battery 2-3 times; specific power, flywheel battery is higher than the general chemical batteries and internal combustion engines, its fast charging can be completed within eighteen minutes and energy storage for a long time. Both ultra-fast charging and no chemical power of his loss of life issues, the battery life is much longer than the whole variety of chemical batteries. More importantly, the flywheel is purely mechanical structure, unlike the internal combustion engine to produce exhaust pollution, but also no chemical reaction process chemistry of the battery, does not cause corrosion, nor problems treating the recovered waste. Section with a diameter of twenty 230mm, the quality of 13.64kg flywheel battery car, with mains charger car battery needs six hours, just 15 minutes fast charging car batteries agents, a charge driving range of up to 560 kilometers. Dual function of the motor. When charging the flywheel motor runs as the motor to drive the flywheel in an external power supply, driven to achieve high speed, thus completing the power - the conversion of mechanical energy storage process; discharge, flywheel motor generator state run, driven flywheel energy exporting complete mechanical energy - releasing energy conversion process. 2. What should be noted that after replacing the battery? There may be insufficient capacity of the new battery, including the original battery on the new car factory, may not 100% power. So after replacement of the battery, or buy the best brand new car after car battery, you need to let the engine run a bit longer 12v car battery, ensuring that the battery can be fully charged. 3, the vehicle for a long time do not open the battery damage it? As the battery will self-discharge, if the vehicle is not the case for a long time may lead to run out of battery power, and ultimately could not start the vehicle or damage to the battery. If the vehicle is not a long time, it is best to keep as much as possible to restart once every 15 days, and allow the engine to run every 20 minutes or so, so that the battery is fully charged again. 12v car battery car battery _ _ Wei Li Po automotive batteries provided by Shenzhen Wei Lai Po Battery Limited.
