Forced Toyota how to choose the battery?

Under the condition of without considering the charging time, nimh batteries have fast charge and discharge and calorific value is small, panasonic full heat exchange characteristics of the core material discharge smoothly comparison for hybrid system works. Wait until the second generation of prius, cylindrical battery has been replaced by square nimh batteries, Toyota said in order to optimize the internal space of the battery pack, photovoltaic energy density hoisting system of the enterprise. Silicon wafer trimming to nimh batteries if only at 40% of capacity To between 60%, can charge and discharge of thousands of times. In addition for nickel metal hydride batteries do not contain toxic substances, main ingredients for nickel, rare earth, recycling security, the difficulty is small, recycling degree is higher. , on the other hand, the heat capacity of the nimh batteries, electrolyte evaporation are relatively high, the energy density is low, even extreme cases such as short circuit, puncture, the battery temperature are also less likely to cause burning. This & other; Shallow charging & throughout; Battery management can greatly prolong the life of battery, charge and discharge cycles to more than 10000 times. From nickel metal hydride battery to lithium ion batteries, solid-state batteries, and Toyota have been put on the market of Mirai with hydrogen fuel cells, Toyota's & other; Stability & throughout; On the basis of try more possibilities. In addition, because of the hybrid system under the reasonable power output, commonly used in the process of temperature and humidity remote monitoring on battery capacity is around 10%, the maximum power consumption can only in extreme circumstances to 40%, so the battery remaining capacity is in less than 60%. Ordinary lithium ion battery charge cycle in about 500 times, nickel metal hydride battery is around two thousand times. Statistics show, in the case of full electricity storage, nickel metal hydride battery power will release by 25% per month 35%, while the lithium ion battery self-discharge rate only 5% per month 9%.

hybrid in the process of operation, the engine's role is to maintain smooth running at high speeds, the motor working time is mainly in the startup phase and lower speed stage, besides motor will be automatically converted into the generator will run body of energy into electrical energy stored in the battery. So in the long-term cost control, nickel metal hydride batteries are relatively. So no matter where the wind blows the future, can catch up with Toyota, can even take up a phenomenon by skill. For hybrid air panel logo graphic battery's main job is not range, auxiliary engine air panel logo graphic but cooperate with motor to achieve the best condition, a combination of fuel efficient cost control is the key. Photovoltaic enterprise, however, Toyota did not put all your whole lifeline in nickel metal hydride batteries, the Toyota prius with high version of the 4th generation and plug-in versions carry is lithium ion battery. Silicon wafer trimming to but both cylindrical and square, from the first generation of prius in 1997 until now corolla, camry, take-away lithium battery rental Toyota has been so passionate about nimh batteries.
