Description
Technical field
The present invention relates to vehicle charging system, and in particular to a kind of charging pile system and its controlling party based on Internet of Things
Method.
Background technology
Electric vehicle（EV）Need periodically to recharge, this is completed by the way that EV is connected into charger, the charging
Device receives its power from supply line.The power consumption characteristic of EV chargers is such, when EV original charges, EV chargers
Draw substantial amounts of power；On the contrary, when being connected to the charger without EV, or when have EV connections but it have it is " almost full " electric
During the electric charge of lotus or " full ", the charger needs considerably less power or does not need power.
In all cases, charger draws the time of power and the ratio of the time for EV chargings less than 100%, and
, may be very low under certain situation, only a few percent.Although charger can automatically turn off EV and fill when EV chargings are expired
Electricity, but the basis instrument of supply line and other particular locations is the specified power to support approximately fixed amount, is thus made
Charger is not efficiently used, be more unfavorable for the charging experience of user, if it is desired to more chargers, then must be with
Extra cost and delay, which increase, builds extra electrical equipment infrastructure, greatly increases extra cost, influences EV accreditation and smoothly
Into market.
Meanwhile, during EV is popularized, plug-in hybrid vehicle is also required to recharge, to utilize and set up base
Plinth sets the lower cost of energy of association, as new-energy automobile especially pure electric automobile especially exists in the world
China popularizes rapidly, and electric automobile is also assorted different due to producer, standard, battery management system, charging station（Stake）Quantity
Less, the problems such as irrational distribution, user are to the worry of battery bag charge differential, as restriction electric automobile routine use facility
Property and the maximum bottleneck further popularized.
Application No. 201480025893.3, the applying date are 2014.05.13, apply for that artificial Tesla Motors Inc. discloses
One patent name is the PCT Patent Application for entering China of location-based charge control system, and the patent provides one
The method that the batteries according to the charging instruction collection of location sensitive automatically to electric vehicle are charged is planted, according to automobile
The different position in place sets different charging instruction collection, and charging instruction collection is limited comprising preset charged plan and preset charged level
System, different charging plan and different charge level limitations are preset for different charging station and position, and user is according to car
Position selection charging instruction collection in preferred charging station and charging plan, the charging method is by electric automobile according to position
Select the mode of charging station, although improve the applicable sex chromosome mosaicism of electric automobile and charging station to a certain extent, be prevented effectively from
Load of the electric automobile to power network causes unstable risk, and causes charging system to meet the consumer relevant with convenience
Expect the potential energy-conservation being associated with electric vehicle, but the charging inlet in the charging method can not be matched and electronic vapour
The adaptable charge information of car battery bag, and when charge user is more, being mutually matched between electric automobile and charging pile
There is also many obstacles, the waste of electric power resource is on the one hand caused, on the other hand in busy period of charging, charging pile is applicable
Position is difficult to find, if all on the one hand causing the waste of a large amount of electric power resources, the opposing party using peak power output charging pile
Face also make it that the cost of charging pile, charging station is too high, the experience of user is influenceed, so as to influence the popularization and application of electric automobile.
