The car wash water gun uses a 500 amp lithium battery
Outside car wash shops, first use a high pressure water gun to wash the car body. the car, then spray the car wash fluid (this can also be a detergent that can damage the car paint). This approach will seriously damage the car's paint! Since the car body is covered with sand and gravel, the fine sand and gravel rub against the car paint when washing with a high-pressure water gun, causing scratches.
After spraying the car wash fluid, the car wash shop worker uses a car wash sponge from top to bottom, then from bottom to top, and sometimes wipes the wheel hub then the bodywork. Then the body paint is dried again with the same operation. In a single applicationn, the painting will be covered in sunburst patterns.
The capacity of lithium iron phosphate battery differs from 500 mAh. Does this have any effect?
The 5.0 Ah battery can be used for 2.5 hours.
The lifespan of a lithium battery is not calculated in years, but in cycles. The lifespan of a lithium battery is "500 times", which does not refer to the number of charges, but to one cycle of charging and discharging.
Lithium battery is a type of battery that uses lithium metal or lithium alloy as positive and negative electrode materials and uses non-aqueous electrolyte solution.
The impact is certain. For small capacity batteries, the greater the difference in capacity, the greater the impact. If it is a large capacity 50 Ah battery, this difference in capacity is significant. normal, and the greater the difference in capacitynde, the more the battery life decreases (for a balanced battery, the iron-lithium charge and discharge cycles are 2,000 times).
Of course, lithium batteries need to be combined in series and parallel for use in electric vehicle batteries (or combined with 12/24 V for use in other electrical devices. They are used for a long time). , have low capacity, charge and discharge quickly, and are prone to premature aging. Although the lithium battery protection board is balanced, its balancing current of 50mA is too small and the rebalancing time is too long.
The conventional method is to group batteries based on their internal capacity/resistance. For example, 48V requires 16 strings, so each string of batteries can be connected in parallel with similar internal capacity/resistance, et. then connected in series.
After use, check the charging and discharging voltage status of each parallel group every year (the ant board with Bluetooth directly displays the voltage on the mobile phone if the difference is large, the groups should be). dismantled and reorganized.
