Description

直流充电桩功率智能分配系统
技术领域
本发明属于新能源和电动汽车充电桩领域
背景技术
目前市场上的充电桩基本上都是一车一桩来充电或者一桩两枪充电(我们用A，B命名两充的枪)，但是在两枪充电中充电功率都是平均分配给两车的，其中A枪给一辆车充电当快要充满或者不需要更大功率充电时A枪部分功率是被浪费。这时如果B枪接口的新能源汽车需要更大功率充电，而A口富余的功率没有办法转移到B口来充电，这样就造成了同是一个桩有些电源模块一直在工作，有些模块一直没有工作。这时候的充电桩没有发挥其最大功效
发明内容
本发明对传统的直流充电桩进行改进，我们以双枪版120KW为例说明充电中的功率调节，首先我们的充电桩是属于智能充电桩，如下图所示充电桩会实时探测端口A，B在充电工程中需要的电压和电流，以及汽车CAN总线所传来的车辆数据信息，充电桩将检测到的信息汇总传到后台充电管理系统进行分析，当充电口A开始充电，充电口B没有在充电时，我们通过控制输出端开关将所有电源模块都连接到端口A输出端就可以实现A端口端独输出120KW功率，当B口有车辆开始充电时，我们的智能充电桩将会把60KW 的充电功率先从A端口的连接断开然后在将其切换到B端口，然后两个端口同时给两辆车充电，如果B端口的汽车急需尽快充满且B端口的汽车能接受的最大功率为100KW，这时我们的智能充电系统通过计算就会给B端口接入100KW的输出功率首先保证B车的正常快速充电，然后将剩余功率留给A端口可以保证A 端口缓慢充电，当B端口在充电到80％左右电流开始下降，不再需要100KW这样的功率来充电的时候，我们的智能电桩会从CAN总线读到车内电池的信息然后进行分析在确认不再需要100KW的功率时，充电桩会将多余的功率逐步从B端口断开，然后在将断开的富余功率加载到A端口上，使得A端口上的充电功率逐步加大，当B端口已经充满电的时候，我们的智能电桩首先将B端口充电链路断开是B停止充电，然后在通过CAN总线和A端口的汽车匹配在确保A端口所需的最大功率后我们将合适的功率在切换到A端口确保 A口能够快速充电，当我们需要快速切换充电功率时我们可以通过后台数据控制中心发出控制命令，然后命令就会通过网络传导所在的充电桩，然后将信息传达给充电桩，接着就会对需要改变功率的端口进行功率改变，从而保证了我们可以在远程随时控制充电桩各端口功率的调节，满足不同用户对充电的要求。

具体实施方式
本发明用于解决电动汽车充电桩在充电过程中的功率分配问题，可以随时调整两抢或者多枪中各枪的功率输出，能够更能有效的分配功率，是最应该得到大功率的汽车能够在更短的时间内充满电。
本发明能够更有效的利用现有功率做到合理分配功率配比，更够更大限度的让充电桩利用现有电网容量得到更大的利用率，能够在单位时间内充到更多的电，能够合理分配充电功率，是的更着急充满的客户能够更容易买在自己的需要，能够远程配置和更改功率配置，随时查看在充电的车辆充电信息，随时可以接通和断开充电车辆，实现更精确的控制。
