Electric vehicle lead-acid battery indicator

1, the battery rated capacity:
National standards are in accordance with the provisions of apple a1012 , apple m8511capacity. Ah that is security units used to express the time, it reflects the battery storage capacity greater numerical  the greater storage capacity is more, now on the market the capacity of battery electric vehicles are generally 10Ah, to constant current discharge 5A 120 minutes. 2, the actual capacity of the apple m8244 , apple a1079: reflect actual storage battery the size of power unit with an Ah said. Same time the greater the security, then the greater battery capacity, the continued line of electric vehicles is far more mileage. In the use of process, the actual capacity of the battery will gradually decay. National standards for the new factory apple a1078 , apple a1148 capacity is greater than the actual value of rated capacity for qualified battery. Now on the market such as battery electric bike to galvanostatic discharge 5A want more than 2 hours (120 minutes), greater than (2 hours × 5A) 10Ah. The equivalent of electric cars at a flat on the road traveling for 2 hours or more. 3, discharge cycle life: are referring to rechargeable batteries, discharge until the battery capacity reduced to 70% of rated capacity when the cycle number, adequate electricity and then discharge to a certain depth for the first cycle. The more the number of cell cycle, then the longer life expectancy, the electric bicycle apple m6091,acer laptop battery cycle life of not less than 350 times less than 350 cycles for battery failure. Electric bicycle on the market now, the normal circumstances, for on, off or to drive children to school, in the framework of city traffic every day for about 1 hours (around 25 kilometers), equivalent to a year down cycle batteries 180 around, if the batteries are qualified, you can use nearly two years, when the battery capacity have rated 70%, which is equivalent to electric cars can be driven for 70 minutes, traveling around 30 kilometers.
4, the rated battery voltage and battery voltage: National standards for the battery voltage value of rated voltage, with V volts, said lead-acid battery voltage per cell value of 2V, the market of electric vehicles on each battery cell only 6V and 12V. 6V batteries each are from three acer btp-43d1 , travelmate 220 battery in series composed of single-cell, 12V battery is six cells in series from a single cell. Most electric bike batteries used for the 36V, and from six 6V batteries or 3 12V batteries in series to form batteries. battery voltage means that the actual battery voltage when the output value of power, 36V battery pack voltage is normally between 41V to 31.5V, which is lower than 31.5V battery known as the over-discharge or undervoltage, easy to damage the battery group, the impact of acer btp-58a1 , ace btp-60a1 life.
