Some time prior we wrote about the autonomy in electric bicycles of lithium-particle batteries, despite the fact that out of sight the lion's share of batteries of this type is governed by the same principles. In that post we made a rundown of the primary driver why a lithium-particle battery discharges the energy that has accumulated and therefore, we can determine the distance. This time we will deal with the subject from a more precise perspective and we will delve into the mechanism that makes possible the energy expenditure of our lithium batteries. We will likewise disprove legends about the operation of these batteries since, in numerous events, we are not aware of the technological changes that happen around us, appeasing ideas that were real before however now are definitely not.
There are numerous types of lithium batteries with different chemical blends and therefore differ in their capabilities and deficiencies. The electrochemical cells that we use in our batteries are composed of a NMC cathode (cobalt oxide, nickel, manganese) and a graphite anode that are the cause of the REDOX reaction (oxidation-reduction) that takes place on account of the properties of the oxide of lithium. The operation is relatively simple, and we state relatively because in the event that we analyze the physical and chemical properties of the materials that make its operation possible, the subject becomes extremely dense and complex.
In rundown, a battery of this type works by putting away energy and releasing it through the process of electrolysis and the most notable property of lithium is basically that the electrolysis process can be repeated up to hundreds or thousands of cycles. The useful life of the cells is determined by several components, for example, the time of use and disuse, the temperature or the number of cycles of stacking and emptying. What is inevitable is the chemical degradation of lithium, which causes its properties to decrease with each use. This is due to several variables that we will expose next.
It's 9:45 and the phone rings at the Legend eBikes offices . A client who claims a Legend Etna needs to converse with Ramón, our head of SAT. The client requests an explanation about the slight decrease in autonomy of his Panasonic-Sanyo battery of 10.4Ah since, after giving it an intensive use, he has noticed that the heap capacity is never again that of the main day.

Numerous users wonder how to improve autonomy in electric bicycles. This is something that we usually see, and not just in electric bicycles, likewise in electric vehicles, smartphones, workstations and for all intents and purposes any device that requires the use of lithium battery for its operation.
What's more, is that many are not aware that the electricity storage landscape isn't as front line as it seems and, in spite of the fact that the facts confirm that much progress has been made from those old and heavy lead batteries, the current technology has several disadvantages that we should have in record on the off chance that we need to extend the life of our batteries.

1. Newton's second law
In spite of the fact that Newton's second law explains the relationship between power, mass and movement, it isn't our intention that the reader solves equations to determine if his battery will measure up, so we will summarize it in a substantially more down to earth way.
It might seem self-evident, however there are people who don't fall into this very important detail, and is that the more you weigh, the more energy will be necessary to move. When we hear figures, for example, the distance we can travel with a heap, we should bear at the top of the priority list that these figurings are based on a standard that is a cyclist of 70kg. Therefore, the more we outperform this figure, the less autonomy we will get from the same battery. Similarly, the less weight we have, the more kilometers per stack we can travel.
2. Visit profile
This section is governed by the same principles as the previous one and is of equal or greater importance, since the weight of the person passes to the foundation.
A route through a slope is rarely linear, either by city or countryside, it is regular to pedal on slopes and variable soils or curves of numerous types. Clearly, if our route is ascending, the measure of energy we need will be greater. Once more, the values ??that we can see in the specifications of any battery are based on guidelines and these are based on a neutral grade tendency, that is, on a plane.
3.Interruptions of travel
The highest energy utilization happens in the begins. To overcome the resistance represented by the combined weight of the bike in addition to the cyclist from halt to a speed of 25 km/h, a great deal of energy is used, considerably more than that used to keep us consistent at that speed for quite a while. This is because once we have reached a consistent speed, just energy is used to overcome the mechanical resistance that can be offered by the mobile elements of the bike and the breeze resistance. For viable purposes, in the event that you need to drag out the autonomy of your bike, endeavor to dependably keep up the inertia and don't hustle when you are moving toward a red light that forces you to stop. Better anticípate and sees reducing the speed of steady shape as you are getting closer and, hopefully, when you arrive it will have already
turned green.
