When the hybrid engine is lithium stock in parallel both engines can propel the car alone or together. A good example would be Toyotas' Hybrid Synergy Drive (HSD). Capable of being propelled at low speeds by the electric motor, the gas engine takes over at higher speeds. This allows both engines to perform in their optimal situation.
Things certainly have changed over the years. There are enough lithium facts options available today to make a person's head spin. There are even more variations and innovations in the works as I write this. While the scope of this guide will not be able to cover every type of power drill in existence, we are going to try to cover most of the bases. My goal in writing this article is to help those who might be having difficulty deciding which type of drill they need, so let's get started.
The lithium-ion battery is light years ahead of the earlier batteries and considerably better than the Nickel-cadmium (Ni-Cd) or the nickel-metal hydride (Ni-MH) batteries which are still being used. These batteries are less expensive but the Li-ion batteries are far superior in three ways.
The mating lithium bettery stock process between the two engines can be in series or in parallel. When the two powertrains are mated in series, only one of the motors controls the cars movement. The other one simply assists the first, dominant engine. This occurs most often in mild or assist hybrids. The Saturn Vue Green Line Belt Alternator System (BAS) is a good example. The concept vehicle named the Volt from GM is another good example of a series (but not a mild) hybrid.
The only drawback on this type of lithium based battery is the high cost. Since it is expensive, it makes sense to use it the right way to extend its service life.
For jobs where the batteries are required to be light weight as well as being reusable, then lithium batteries are ideal. But if a battery is needed to be very reliable or to remain unused for a long time then they might not be the right batteries for it.
