Electric car battery problem to cure repair summary: 1, make up water. Water shortage of electric tricycle, all out of the question. And solubility related. 2, temperature. High temperature effect is good. And activity. 3, high voltage low current. Generally speaking brand electric tricycle, the battery voltage is higher than doubled. Current 0.01C. But not absolute. Only cure for severe 0V battery, a much higher starting voltage electric tricycle manufacturers, 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. Chemical battery electric vehicle battery types can be divided according to the nature of work: a battery (primary battery); secondary batteries (rechargeable batteries) lead-acid batteries. Where: a battery can be divided into: paste-type zinc-manganese batteries, cardboard manganese batteries, alkaline manganese batteries, zinc-silver button batteries, button lithium manganese batteries, button-manganese batteries, zinc-air battery, a lithium-manganese batteries. Secondary batteries can be divided into: Nickel-cadmium batteries, nickel hydrogen batteries, lithium-ion batteries, secondary alkaline manganese batteries. Lead-acid batteries can be divided into: open lead-acid batteries, all sealed lead-acid batteries.
