Parsing the battery pack use environmental problems

Source: 2020 - 04 - 01 then hits: battery working environment. 1, the battery pack waterproof! Short circuit fire probability! 2. Battery shock! Electric vehicle in, can't suv! Also can't use the battery pack shell to cushion the impact, the deformation will cause short circuit! As far as possible with the method of network frame + cushion + carton. If there is no grid support, the battery pack in long-term extrusion activity can lead to nickel chipped! 3. The battery pack can be conditionally provide heat conduction channel. In energy conversion, the timely heat conduction can realize optimization of the battery. Steel shell + auxiliary fan, is a common solution. The small series of super glue before packing is also a solution, is the late maintenance of trouble. 4, anticorrosion, battery rust for a long time, as far as possible do anti-corrosion measures. Five, the lithium battery maintenance board option 1. Two less than 40 a electric wheels is enough, three more than 80 a electric wheels is enough. Concrete should be according to their own motor power to choose. 2, voltage to match, 60 v is established, to distinguish between three yuan, and lithium iron, but also distinguish between the number of strings. 3, as far as possible with large capacity, low power, stable and durable. As high power battery, must calculate discharge rate is supported. With conditions as far as possible choose low voltage board maintenance and maintenance to a certain amount of residual battery. For example, 4. 25 v maintenance than 4. 2 v ~ 4。 1 v, because the battery will not put 100% of the battery, can't insist to the limit. But most maintenance board design didn't notice this, a small number of manufacturers are doing.
