Electric car battery problem to cure repair summary: 1, make up water. Water shortage, all out of the question. And solubility related. 2, temperature. High temperature effect is good. And activity. 3, high voltage low current. Generally speaking, higher than the battery voltage is doubled. Current 0.01C. But not absolute. For severe curing only 0V battery, a start voltage even higher, current smaller. 4, the pulse frequency. This is not essential. 1945 in favor of the argument, saying that the crystal resonator is purely for granted, there is no experimental basis. Suggest that you use 200Hz, 1000Hz, 8330Hz experiment a bit. Electric car battery maintenance 6, not to let the battery discharge cargo electric tricycle, so that sufficient light put ground. When riding, be careful not to let the battery discharge cargo electric tricycle accessories, battery discharge to the termination voltage electric cargo tricycle manufacturers, continue to discharge as discharge. Easily lead to serious over-discharge battery power loss, thus greatly shorten its life. So should try to avoid using the batteries depth of discharge, so that sufficient light put ground, in general, should be done in order to discharge the battery to recharge a battery optimum depth of 50%. Electric bicycles are generally equipped with undervoltage protection, when only one battery charge monitor display lights up, you should turn off the power cargo electric tricycle price, using the foot, as fast as possible and try to charge the battery to avoid battery discharge.
