List of Frequently Asked Questions

1. How many electric vehicles has BYD manufactured?

There are two all-electric models in BYD's EV lineup beside hybrid ones, the GreenCity electric bus and ev6 sedan, totally powered by BYD's self-developed Fe battery and both featuring a stunning range per charge.

2.What advantages do BYD's EVs harbor compared to fuel models?

1)Environmental-Friendly: No toxic will be exhausted;
2)Energy-Saving; Lower energy consumption for the same travel mileages;
3)Money-Saving; Less operation cost due to low energy consumption.

3.What is the useful life cycle of a photovoltaic system?

A photovoltaic system should last for at least 20 years to be eligible for the statutory electricity feed-in compensation. It is generally believed that a life cycle of 30 to 40 years is useful. Solar module manufacturers basically offer a 25 year warranty at an efficiency loss of no more than 20%.

4.What components comprise a photovoltaic system?

The basic component of photovoltaic system is solar module, which consists of a number of interconnected solar cells. Solar modules are combined with each other to form a solar generator. The direct current generated by solar cells is directed to the inverter. This device converts direct current into alternating current, which is fed to the public grid via an export meter. During the periods of low sunshine, electricity is taken from the grid. The grid therefore serves as storage for the photovoltaic system.

5. What is Inverter?

An inverter is an electrical device that converts direct current (DC) to alternating current (AC). The converted AC can be at any required voltage and frequency by utilizing appropriate transformers, switching and control circuits.
Static inverters have no moving parts and are used in a wide variety of applications from small switching power supplies in computers to large electric utility applications of high voltage direct current that transport bulk power. Inverters are commonly used to supply AC power from DC sources such as solar panels or batteries.
The electrical inverter is a high-power electronic oscillator. It is so named because early mechanical AC to DC converter was made to work in reverse, and thus was inverted to convert DC to AC.

6. What is Energy Storage Station?

Energy storage is accomplished by devices or physical media that store energy to perform useful operation at later time. A device that stores energy is sometimes called an accumulator.
All forms of energy are either potential energy (e.g. Chemical thermodynamics, gravitational, electrical energy, etc.) or kinetic energy (e.g. thermal energy). A wind-up clock stores potential energy (in this case mechanical, in the spring tension), and a battery stores readily convertible chemical energy to operate a mobile phone. Also, a hydroelectric dam stores energy in a reservoir as gravitational potential energy. Ice storage tanks store ice (thermal energy) at night to meet peak demand for cooling. Fossil fuels such as coal and gasoline store ancient energy derived from sunlight by organisms that later died, buried and then converted into these fuels. Even food (which is made through the same process as fossil fuels) is energy, which is stored in a chemical form.

7. What is LED?What is the actual benefit for environment?

In case you have a product that has a defect, please conduct Consumer Care.Our consumer care agent will help you to possibly resolve the defect or will guide you how to fifnd the best repair or exchange solution. Over 1/3 of electricity used worldwide for lighting can be saved.These savings of over 900 billion kWh of electric power would lead to a reduction in global emissions of more than 450 million tons of CO2.
