Electric vehicles use lithium iron phosphate battery matters needing attention

Source: 2020 - 04 - Electric car 06 and clicks: time matters needing attention when using the lithium iron phosphate batteries using lithium iron phosphate battery electric vehicles is the trend of The Times, the lithium iron phosphate battery prices have fallen sharply. General specifications of the 48 v / 12 ah lithium iron phosphate battery components has dropped to 700 yuan. Current production has not yet been finalized, however, is still in the experimental stage, can be installed directly in the market using very little product is mostly semi-finished products, need to be modified. In this paper, 48 v / 12 ah lead-acid battery ( Refers to the ordinary 'T' type battery pack) Instead of the lithium iron phosphate batteries, for example, this paper briefly introduces the lithium iron phosphate battery components purchase and assembly. ( Note: the pool can have the start-up battery products, but can't have electric car battery products, need to customize according to the car) Choose and buy shopping is to buy two things. One is the battery module, the other one is a battery pack, battery charging and discharging control panel included in the battery module. 1. 48 v / 12 ah battery components used lithium iron phosphate battery module has two kinds of specifications. One is 29 cm high, 11 cm long, wide 5 rectangular battery module of the CMM ( See figure 1) And the other one is 16 cm high, 15 cm long, 11 cm wide battery module. Two battery modules by 16 3. 2 v and 12 ah lithium iron phosphate batteries in series. Equipped with charge and discharge control panel, and between batteries and battery, battery pack and connection between charge and discharge control panel, the battery module of charging and discharging outlet wire welding is good. This kind of battery is coated PVC plastic, before the assembly of battery capacity and internal resistance after super, so work more reliable. The first specification of battery module can be loaded into the ordinary 'T' shape battery box height of 33 cm ( See attached figure 2) 。 If there is no test condition, and poor people start work ability best buy this kind of semi-finished products, and it is best to normal manufacturer of the product. The battery components installed in the battery box, the welding on the charging and discharging outlet, basic can be used. Try not to only pay for the battery and charge control board all homemade. So, although a little cheaper, but quality problems is quite troublesome. Buy the battery components usually comes with a charge and discharge outlet and a dedicated charger. One of the discharge outlet is common desktop 10 a three hole socket. However, this kind of socket differ as a result the ends of the earth is divided into two types, a farming is horizontal, a farming is vertical, the latter are more common. Make sure you know what kind of plug for your electric car. The above three hole socket is used for electric vehicle batteries, grounding is hanging, actually just as fixed pile. In order to expand the application range, some directly pull the pole. If the original electric car battery ground jack to plug is' T 'shape, it can be applied to any of these sockets. 2. Battery box select all the brands of 48 v / 12 ah lead-acid battery using the same main dimensions of the 'T' box. The only difference is that the width of the battery box at the back of the panel. Generally there are 7 cm and 5 cm, to pay attention to when buy battery box behind the plate width must be the same as the original battery box. In addition, the battery box had better choose high mechanical strength of the ABS engineering plastics materials. Of course, you can directly use the old lead acid battery pack. Even so, it is better to buy a second battery as backup, because it is under the condition of the old batteries will not work.
