The energy density of lithium batteries is so high, why doesn't Toyota choose to use lithium batteries in its hybrid system? Because Toyota does not use lithium batteries in large air vehicles, and if Toyota has pure electric vehicle technology, it will be the focus of the automobile market.
Although the two sales are far apart, this does not prevent Tesla from overtaking Toyota in terms of market value and becoming the most valuable automaker in the world. The ultra-high market value is a recognition of Tesla's development of purely electric vehicles throughout the automobile industry.
The automobile industry has entered the new energy era, and all automobile manufacturers are adapting and stabilizing. The two words "" can sum up 70% of the reasons why Toyota's hybrid technology never considershave resistance. Take the resistance because when the main objective is achieved, the energy density of the battery becomes less important. Although compared with lithium-ion batteries, it has low exhaust voltage, low energy density and short life, the most important thing is safety and stability. The development of micro-new energy vehicles is the same as the core development technology of new energy vehicles. Power batteries, ternary lithium batteries and lithium phosphate batteries have become the main choices for power batteries. Batteries become the main theme of the industry. Toyota still insists on the use of nickel-metal hydride batteries in hybrid technology after 23 years of play. Volkswagen, its biggest business competitor, has also acquired the high technology of Guoxuan and strives to provide. batteryes lithium to meet the needs of clean electric vehicles.Development trend.
As long as there is a possibility of battery damage, even if the proportion is small, it will occur, e.g. , at Toyota with dual power. also uses MH nickel batteries after driving 12,000 kilometers. While driving, he suddenly noticed that various lights on the dashboard were on. I pushed him to check the hybrid system. I went to check 4S and found that the battery was broken. /p>
Luckily the battery was broken! The warranty period is 8 years/20,000 kilometers, and replacement is free during the warranty period. Toyota currently has two hybrid vehicles, one is a gasoline-electric hybrid vehicle and the second is a hybrid vehicle. The other is a plug-in hybrid vehicle. Total sales volume exceeds 1,000 Wan, no large capacity batteryis not required and the number of batteries is much less than that of a hybrid rotary car by adding frequent pulses and surface discharge. Through these strategies, battery life can be extended by using only 40% of the battery capacity to drive the vehicle, and the remaining 60% capacity is still available. Therefore, the charging and discharging time is greatly increased and the service life is very long.
For plug-in hybrid vehicles, to guarantee pure electric range, a large capacity battery must be used. This battery cannot therefore adopt a surface discharge strategy. The lifespan of this battery is not as good as that of a fuel hybrid battery. At present, the He+ plug-in hybrid has not yet been launched, and the battery quality assurance policy is unclear. been verified, so thebattery life is unknown
