Description:Field of the Invention
The present invention relates to a systems and methods for supplying energy to electrically powered vehicles (EPV). More particularly, the invention relates to the integrated systems and methods to manage a process for quickly charging batteries and meanwhile implementing cloud-computing network connected battery health monitoring devices to transmit signals whereby continuously monitoring the health state of all the batteries in order to effectively and safely supply energy to the electrically powered vehicles.

Background of the Invention
Electric vehicles (EV) are the most popular, energy-saving and environmentally friendly green travel means of transportation. Electric vehicles generally choose charging stations for charging. The number of charging stations has greatly increased, and there are many electrical equipment in the charging stations, and the traffic flow at the station is large. Whether it is in the charging process or not, there are great safety hazards. With the rapid development of electric vehicles (EV), the EV Charging infrastructure is in demand with a need for charging capabilities all across not only in India but across the globe.
To support the demand, the deployment will require a charging facility that provides user a better experience, provide a way to charge the vehicles properly that is appropriate to the weather conditions specifically like country India. Summer times can be extremely hot and sometime of the year, the weather can be quite cold. Both these conditions will have an impact on the battery performance and the way the charging is approached. Further, to provide a way to charge vehicles safely. Some parts of India can experience extreme rainy conditions. Charging of vehicles in such conditions needs to be addressed under the context of utmost safety
Currently products are plain charging units provided by the OEMs. They do not cater to external/environmental needs of the charging process. As the batter sizes increase, EV cars that come in for recharge, the battery temperature will be quite high. When batteries are recharged at such high temperatures, there is a chance for them to catch fire and even in some cases, explode. Also, battery not in the optimal will not gain sufficient charge thereby delaying the process. Charing battery is extremely hot conditions can also lead to faster degradation of the battery. These external conditions and setting them right for charging the EV is not available in the market.
Heat is the worst enemy of any battery. Temperature compensation to adjust for temperature variation improves life of the battery by 15%. Charging nickel-based batteries at higher temperatures lowers oxygen generation that reduces charge acceptance. The charger is led to read that that the battery is fully charged when it’s not. A graph in FIG. 5, shows a strong decrease in charge efficiency from the “100 percent efficiency line” when temperate is above 30°C. At 45°C, the battery can only accept 70 percent of its full capacity; at 60°C the charge acceptance is reduced to 45 percent.
Lithium-ion performs better at elevated temperatures however, prolonged exposure to heat reduces longevity. As the requirements of electric vehicles are increased, the requirements for the power performance and fast charging performance of battery systems are becoming higher and higher. It is preferred that the temperature during charging of the lithium ion battery is maintained in the range of 20-35 °C. When the lithium ion battery is below this temperature range, the phenomenon of charging lithium deposition or charging and discharging power is prone to occur; when the temperature of the lithium ion battery exceeds this range, the cycle life of the lithium ion battery is drastically decreased, and heat may also occur. It is always challenging to charge the battery with the optimal temperature such that the charge acceptance is the highest. Therefore, a need exists in the field of vehicle battery and energy supply to provide a new and improved integrated systems and methods to resolved all the above discussed difficulties and limitations.

Summary of the Invention
Example embodiments enable the provision of an integrated system and method which is capable of providing for relatively fast charging considering the weather conditions and also the temperatures of the battery as the electric vehicle enters the facility of charging. Regardless the increase in charging speed, example embodiments further enable efficient and safe charging that focuses on the identification of current status of the charge on the basis of measuring internal battery temperatures.
The technical solution of the present invention is an integrated charging stations which has built in temperature checks that considers bringing the battery to the right temperature before the start of the charging. Further, the invention is to improve the charge acceptance of the battery. The invention integrated system is designed to charge the battery approximately between 35°C to 50°C. By doing so, the integrated system avoids mis-reading the actual charging of the battery. Further, the integrated system is capable enough to increase charging speed by 35%. Further, the integrated system of the invention avoids EV owners running out of charge.
