My small room and the distance is about 70 ~ 80 meters, my electric car is ordinary kind of Tianjin sunshine, 4 batteries, 48V, now want to take a little real power to the electric vehicle charging, do not know how many flat cable. Thank you, the power house usually lighting and charging, I saw a 1.5 flat on the Internet, 2 core cable, but the copper alloy do not know can not be used, please, professional advice.
First，From various safety requirements,220V AC power lines should not be hung outside the wall,Even a low voltage line,Hang down from the top floor,The cross sectional area of the wire and ordinary telephone wire is too small and the strength is poor,
This kind of wire itself is not able to withstand such weight and tension.From the top down, recharge the first floor or basement electric bike,Can only be extended low voltage wires,The charging current is generally 2 AMPERES circuit strength,For extended wire total resistance,There are certain restrictions,Especially for lead-acid batteries,
The charger has different charging current, and the charger has different output voltage,When the total resistance of the extended wire is too high,The charger is too small for the initial charging current,The battery is considered full,Start with a green light,Charging at low voltage and small current,The result is a few days continuous charging of lead-acid battery,It's also full of electricity.Even though the red light, the high voltage and the high current charge first, the red light soon turns green.For lithium batteries, they are allowed to be charged with long wires, but only for a long time.
