At the Frankfurt Motor Show, Honda also announced the mass production version of HondaE, and also announced the two-way connection system HondaPowerManagerPrototype for EVs and smart grids. This design is to consider the realization of V2G functions, which can connect electric vehicles to the owner's micro smart grid. The two-way power transmission system adopts two charging interfaces CCS2 and Chademo. From my personal understanding, this device is intended to be able to easily control the energy flow back and forth through the direct connection with the vehicle battery (through the DC interface), and it can also quickly charge the vehicle. This AC/DC process can be completed through this PowerManager. As discussed earlier, the on-board charger is taken out of the car, and the physical structure and connection method are similar. Note: For general use, Honda's AC charging method is the same as HondaPowerCharger's household charging pile, slow charging single-phase 7.4kW, as shown in the figure below, the charging interface adopts the European standard AC interface of IEC, which is a charging method that depends on the on-board charger. If this PowerManager is used at home, the home charging station is not needed, and the on-board charger in the car is basically not needed. Earlier this year, Honda actually showed this device. This is the state shown in April. There is only one CCS interface. This is the state conceived in 2017. This product and Honda's hondae are basically a processing method conceived at the same time. This is a product designed by Honda in the early days, and it is filed on the Chademo website. The three-phase input used here is connected to Ratedcharge/dischargeoutput: 5.5kWRatedinput/outputvoltage(AC): single-phasethree-wiresystem AC100/200VInput/outputvoltagerange(DC): DC150 ——450VCommunicationProtocols: V2HprotocolDCVersion2.1 Summary: Non-utilitarian, from a cost perspective, first popularize low-power DC charging facilities, and then select on-board chargers for future vehicles. The path for this to be done is more proactive than automakers. , You may be more accepting
