Recently been crunching their new phone, which has a very interesting software, cell phone battery is protected and maintained in a program, in which so-called \"trickle charge\" mode I think about the electric car charging mode , and finally found is, in fact, we actually have with the car manufacturers have long been advocated by contact with high-tech systems, such as mobile phones, laptops or charging of pad system, and even the charging system touted by manufacturers than car charging system is more advanced. So today let\\ s look at the electric car charging mode. Electric and charging method

vehicles-3/">electric vehicle charging methods can be divided into constant current charging, constant voltage charging and fast charging pulse three ways, and according to the demand for vehicle charging permutations and combinations, and while we understand the way before charging electric vehicles, electric vehicle battery charging method will inevitably need to understand something:

1, the constant current charging: in fact, this charging method is the most common, is the charging process, to set the charge current to maintain the same approach. This charging method is a standard charge, including trickle charge and minimum charge, the standard charge, as well as high-rate charging four methods, and this is what we are several ways around cell phones, notebook computers and other electronic products, the most common charging method.

Focuses on what the trickle charge, many will choose a smart phone battery maintenance software, which will power the battery is full after trickle charge, and its meaning to compensate self-discharge, so to keep the battery fully charged state in the approximation of continuous small current charging, the battery is fully charged to make up after as a result of self-discharge capacity loss, also known as maintenance charge mode.

2, constant voltage charging: refers to maintain constant voltage charging method of charging, the battery charging current age of increased electric decreases. The film should be a reasonable charge is sufficient to charge the battery current will tend to zero.

3, pulse fast charge, first with the pulse current to charge the battery, then let the battery short-term, large pulse discharge in the whole process of charging the battery re-charge and discharge method. Electric vehicle charging

1, the conventional charging method: such a constant voltage charging method is used, the traditional way of constant current to charge the car. This approach has been very low charge current for battery charging, the current size of about 15A, 120A · h If the battery, for example, charge at least for 8 hours or more. This charging method is the more common electric vehicle charging mode, because the cost is low and job stability, usually charging device charging civilian power 5 ~ 10kW, 380V three-phase four-wire or one-way 220V power supply. But the drawback is slower charging rate.

2, rapid charging: in 150 ~ 400A of its high charge current for battery charging in a short time, compared with the conventional charging method, the manufacturing and installation costs higher. Its main purpose is to complete in a short time to recharge electric vehicles, such general charging power charging mode are greater than 30kW, 380V three-phase four-wire power supply.

Although the charge faster, but because of the rapid charging process, the battery heat rapidly increased, while violent chemical reaction within the battery, so battery life will be some impact, so that the later use of electric cars cost substantially increased.

3, the wireless charging: This is a relatively new charge model, the concept is similar to the principle of mobile phones, is a way to meet current electrical energy is converted to a particular technical standard or thin laser beam, and in the car receiver as a location to install the access port to charge.

4, replacement rechargeable battery: the battery energy is depleted, with a fully charged battery or battery pack for replacement. But this is the model in the country has not yet appeared, the general type of model, the battery go brand dealers, manufacturers of all, users only need to rent electric vehicles battery. However, some of these methods to be resolved, first of all, this battery replacement system, the initial cost is high, such as expensive machinery and battery, second, hesitation, or store large amounts of full-power battery is not charging a lot of space needed, and finally , and the ownership structure of the battery the same as the uniform and other issues need to be resolved.

5, the mobile charge: batteries for electric vehicles, the ideal situation is to charge in motion, so that you can reduce the maximum mileage and popularity for the electric car driving constraints, but these models need the government to charge support can only be because of the need relates to the erection of the road under the road charging system. We played a bit like bumper cars, just below the power supply side on the road, you can contact or inductive charging.
