to his car is charged every pure electric vehicle owners have experienced, and have become accustomed to things. But many look back with a pile charging condition of pure electric vehicle owners, their habits most of the evening commute charging, unplug the charging post to work the next morning, so the operation is very common. Then this will lead to overnight charging wire fever fire? Or with what kind of security risk it?
clear heat source
Why the charging process will generate heat? Heat and from where? In fact, very easy to understand for the average home charging pile, most are low-power AC charging pile, most of the heat accumulates in the battery pack section, rather than charging cable. Charged firing line is often because the line itself with the charging resistor, the current through the charging line, is bound to have some heat. But this part of the heat of the pile itself or the battery charge than the group itself is very small, and now the charging line have numerous safety standards, do not worry.
automatically powered down to absolute risks
on the market today, whether it is or pure electric vehicle charging poles are with power management systems. Power management system when the battery pack has been fully determined, the power supply will automatically cut off to ensure safety. So overnight charging this scenario, after a full charge pile has stopped working, the battery pack will be put on standby, relatively speaking, it was able to get security guarantees.
Summary: Today’s automobile industry to this level, engineers have to pay to see. On these issues, engineers in the test phase has been considered clearly and solve them, consumers need not worry too much.
