Primary battery: throw away when used up and cannot be used repeatedly, such as: carbon-zinc battery, alkaline battery, mercury battery, lithium battery. Secondary batteries: rechargeable and repeatable users, such as: nickel-cadmium rechargeable batteries, nickel-hydrogen rechargeable batteries, lithium rechargeable batteries, lead-acid batteries, solar batteries, crystal gel batteries, lithium iron phosphate batteries.   According to the purpose […]

The battery is a chemical substance, so it also has a certain service life. Primary batteries such as dry batteries (including ordinary alkaline batteries) cannot be charged. Of course, the service life is only once. For rechargeable batteries, generally we use the number of recharges to measure the length of their service life. The cycle

1. The car owner has no awareness of battery maintenance, causing serious damage to the battery. You have to wait until the battery can’t run before repairing and maintaining it. At this time, repairing becomes more difficult. In fact, if the maintenance is performed once every 6 months, the life expectancy will be extended a

1. Imbalance. Caused by differences in capacity and voltage. Often a severely backward. Repair method: change, but do not use a new one.   2. Water loss. Caused by overcharge. Causes of imbalance and charger. Repair method: replenish water (distilled water).   3. Vulcanization. Caused by undercharge. Causes of water loss and charger. Repair method:

1. There are three main driving methods for electric vehicles: one is wheel drive, the other is mid-drive, and the other is suspension drive. Electric bicycles on the market are mainly driven by hubs, which are better for rear-wheel drive, and the front-wheel drive performance is relatively poor. 2. The location of the battery should

1. Standard type: The motor power of this type of electric vehicle is generally 150W. It is characterized by a simple and smooth shape, a continuous mileage of 40-50km, simple operation, moderate price, and the price is about 2000-2600 yuan, which is more suitable for longer commuting distances. For users who have certain mobility in

1. Check the appearance to see if the surface of the paint and electroplated parts are in good condition. 2. Operate according to the manual and check the working status of the whole vehicle. The speed adjustment transition should be smooth, without shock at the start, and the wheels should rotate flexibly。 It is lively

The continuous mileage of an electric bicycle is defined as follows: “When the new battery is fully charged, the rider’s weight is configured to 75 kg and rides on a flat secondary road (with no strong wind), and the battery voltage is less than 10.5V/cell. If the power is cut off, under the above conditions,

1. First adjust the height of the saddle and handlebars to make them in the safest and most comfortable position, especially the height of the saddle. It is best that both feet can touch the ground at the same time when you need to stop during riding. 2. Test whether the braking device is effective

1. The whole car is out of power-the main fault is that the battery is welded, the insurance is burned, the power cord and the battery socket are disconnected, the contact is poor, and the converter is damaged. No major problems will occur. 2. Don’t go if there is electricity. Under normal circumstances, you should
