Studies have shown that in California, the evening is equivalent to charging the cost of a gallon (3.8 liters) of 0.75 U.S. dollars Laptop Battery in gasoline prices over the same period pre-tax cost of petrol is slightly less than three U.S. dollars per gallon. Electricity cost of 0.10 U.S. dollars per kilowatt-hour terms, Prius plug-in hybrid electric vehicle (PHEV) electricity cost of about 0.019 U.S. dollars per kilometer. In 2008, several countries, government and industry researchers to focus on research full-electric driving range of vehicles in which to achieve best value for money. In 2008 costing, PHEV drive 30 miles just 1.04 U.S. dollars, if you use gasoline, the cost of running the same distance compared to 3 U.S. dollars.
If a vehicle is mainly in charge during non-peak (eg at night), or equipped with technology that stops during the peak demand charge, PHEV and full-electric vehicles can reduce the operation of power plants in preparation for idle time, more efficient use of the existing Some of generating capacity. PHEV Another advantage is that it can use the vehicle charging network technology to achieve load balancing, or to reduce power load during peak load. By excess
Panasonic Camcorder battery energy sent back to the battery grid, and then used during non-peak electricity cheaper to re-charge, and thus power facilities and their owners are beneficial. Even vehicles that will make increased use of electricity at night, but because usually a high demand for electricity during the day, which can maintain a balance between electricity demand all day, and electricity infrastructure to bring a better return on investment.
Of course, PHEV and full electric vehicles in its development process will encounter some obstacles. The first is the high cost of the battery, weight, heavier, and battery packs will occupy a larger volume of space. Second, many people live without a garage apartment or multi-span houses, vehicles can only be parked in the streets, they must have outlets to achieve all-electric operation; In this case, must be close to their homes, or in the commercial or a public parking lot near the new power socket, so that their full advantage of PHEV vehicles. Although the use of PHEV would reduce pollution in most areas, but the ACEEE study is expected in the region rely heavily on coal, widespread use of PHEV, due to emissions from thermal power plants along with the increase of generating Panasonic Camcorder battery capacity to improve, but will increase the local sulfur dioxide and of mercury emissions.
For electric vehicles and hybrid electric vehicle's battery is a long string of batteries in series composition, in order to achieve more than 200V to 300V or 300V operation voltage. These batteries are particularly vulnerable to damage, but if you need to parallel battery pack in order to achieve the required capacity or power level, the problem will become more complex. A group constituted by the n-cell battery packs, the failure rate will be n times of a single battery.
In addition, because the battery may be interactions between the (one for each cell made out of a little different), so the potential failure rate was even higher than estimated above. Because of production tolerances, uneven distribution of temperature and aging characteristics of individual differences in batteries, the battery string of individual cells may be the stress is too large, leading to premature wear and tear. In the charge cycle, if the battery string, there is a performance panasonic CGA-DU07 battery degradation due to result in reduced capacity, once fully charged, it will maintain the overcharge state, until the rest of the battery to reach full charge up, which would pose potential risks. A result, temperature and pressure, and may cause damage to the battery. In the discharge period, the weaker the battery because it precedes the rest of the battery to fully discharge voltage may even be reversed, leading to battery failure.
Have adopted HEV battery management system (BMS) design, the system has the power state (SOC) evaluation function, the use of advanced real-time molding and analysis to detect changes in battery performance parameters, such as the battery in each battery cell in ampere-hour capacity and internal resistance. This information, together with the voltage, current and temperature, should be recorded in the non-volatile memory in order to keep track of each battery SOC, this feature allows BMS to protect the battery pack in the battery to avoid the worst-off charge and over-discharge. As the battery failure is often the initial battery performance difference between the small and larger over time the results, so this feature helps to prevent premature battery pack of the most common damage.
Ramtron is a nonvolatile ferroelectric memory (F-RAM) solutions, a global leader. F-RAM memory used to store the battery model LUT (support self-learning function) panasonic CGA-DU06 battery for SOC prediction and calculation, as well as health (SOH) logs and diagnostics, such non-volatile memory of the life cycle requires a minimum of 8 years.
In addition, BMS can be documented maintenance records, such as the number of times the battery flooding, with an average depth of discharge, the maximum and minimum temperature. This information is used to prorate the scope of the battery warranty to record the battery abuse, responsible drivers who do not need bear the cost of irresponsible persons.
Meet the AEC-Q100 standard F-RAM devices have the best durability, fast writes, high reliability panasonic CGA-DU14 battery and low power consumption, and is therefore the best solution for BMS applications.
