Can electric cars add a small battery to their shorter range?

We all know that electric vehicle battery has certain cycle count, when its use after period of time, will be a drop in life.A whim: as a result, many users add a small battery, can increase life?To this issue, as a mechanic to analyze for you.

First of all, let's take a look at how to increase the battery.48 v electric vehicle batteries, for example, the four pieces of 12 v battery, if need to add a small 12 v battery to the battery pack, so there are two ways.

First of all, is the way of the parallel, and is the chief drawback of this approach: to recharge the battery pack, when 4 small batteries, new batteries in parallel is not full.If you choose to continue to recharge, so will cause 4 small battery overcharge and damaged.Therefore, unable to adopt the way of parallel.

Second, is the way of adopting series, and is the chief drawback of this approach: high voltage, always likely to burn out the original motor and controller.Why do you say that?Because electric factory, is a necessary collocation, power is different, other parts would be easy to burn out.As a result, even with the method of series, also need to replace other corresponding accessories.Compared with directly replace the new battery, have bit of do more harm than good.

Electric cars life shorter, can add a small battery?Listen to the mechanic how to say!

The corresponding collocation

Second, it is important to note that if you choose to add a small battery to the original battery, need to match the original voltage, current size, the mainest is difficult to obtain the same size small batteries, because there are very few places have separate small batteries.In addition, the battery pack is a big difficulty, why do you say that?General battery compartment, are designed, cannot accommodate a small battery again.So, from this point of see, increase a little the battery did not want to so simple.

Finally, and most important, from the new national standard, the industry of electric bicycle with clear rules, ask its electric vehicle battery is not more than 48 v, this means that if the new increase a battery, electric cars may be defined as overweight electric vehicles.In addition, the industry also increased the management of the electric car industry, if modified secretly electric cars, also will face trouble on the road, and even electric vehicles to be confiscated.Therefore, for this, is not recommended to add a piece of small batteries.

All in all, from the point of these points, electric life shorten, add a small battery is unreliable.So, when the batteries in electric vehicles is not durable, best choice.Daily, of course, to strengthen the maintenance of electric vehicle batteries, will to a certain extent, prolong the service life of electric vehicle batteries.
