1Cov. Tau peb tig muscua txias thaum tusEV Csam xeeb?

When tusweather is hot, if there is no rest place around tuscsam xeeb station, many car owners will ask: Can tuselectric car be turned on in tusair-conditioning to rest thaum tuscsam xeeb process?

Like refueling at a gas station, in principle, it is recommended to charge away from people, that is, when people leave tuscar thaum csam xeeb; this can eliminate potential safety hazards from tussource. Secondly, tusact of turning on tusair conditioner while csam xeeb will increase tusinternal charge load of tusbattery and affect tusservice life of tusbattery.

Therefore, when choosing an outdoor csam xeeb station, try to choose a csam xeeb station with restrooms and other supporting facilities for csam xeeb. When tuscar is csam xeeb, leave tuscar and go to tuslounge to wait.

 

2. Will tusbattery Puas yog sivFast EVCharger?

To be precise, frequent fast csam xeeb will cause certain damage to tusbattery compared to slow csam xeeb.

Because fast csam xeeb uses a current that is several times or even ten times higher than tusstandard csam xeeb current for csam xeeb. In tusfast charge mode, when tuspower is charged to about 80%, tussubsequent power will be fully charged in tusslow charge mode.

If fast csam xeeb is used frequently, tuspolarization of tusbattery cells will be accelerated, causing tuscells to deplete lithium. In tusprocess of lithium analysis, lithium ions will be reduced, which will eventually lead to a decrease in battery capacity, which will affect battery life. Under normal circumstances, let tusbattery rest for a short time after fast csam xeeb, tuslithium metal will return to lithium ion, and tuscritical temperature will return to tusnormal value. However, frequent fast csam xeeb will reduce tusbattery's ability to restore.

Therefore, in order to ensure that electric vehicles can better solve tuscruising range, car owners can choose tus“daily slow csam xeeb, emergency fast csam xeeb” approach, or slow csam xeeb once a week to supplement.

The electric vehicle csam xeeb process is mainly divided into 6 steps: physical connection, low-voltage auxiliary power-on, csam xeeb handshake, csam xeeb parameter configuration, csam xeeb, and csam xeeb end.

When csam xeeb an electric vehicle, tusfirst condition that must be met is tusmatching of tuscsam xeeb gun and tuscsam xeeb interface, that is, tusphysical connection. If tuscsam xeeb gun can be inserted into tuscar normally, tusfoundation of csam xeeb is established. Low-voltage auxiliary power-on is tusprocess of powering on tusvehicle's BMS. Only when tusBMS is powered on can further handshake and communicate with tuscsam xeeb pile, that is, mutual confirmation of tusversion. If tusversion is tussame, tusBMS will send detailed vehicle information and exchange information with tuscsam xeeb pile. During tuscar csam xeeb process, tustwo will generate a large number of messages. If there is a mismatch, tusnormal csam xeeb work cannot be completed.

Normally, once tuscsam xeeb fails or tuscsam xeeb is interrupted, tuscsam xeeb pile will display tusreason code for tuscsam xeeb failure. Once this happens, it is recommended to call tuscustomer service of tuscsam xeeb station or look for tushelp of tusstation staff to determine whether it is tuscsam xeeb fault caused by tuscar or tuscsam xeeb pile.
