Composition of new energy vehicle energy storage wiring harness Jun 09, 2023

energy storage wire harness


The composition of the automotive energy storage power supply wiring harness is composed of wires and connectors of different specifications and performances. The main specifications and performance requirements are as follows:


01) Cross-sectional area of energy storage wiring harness

According to the load and current of the electrical equipment, select the cross-sectional area of the wire. The general principle is that electrical equipment with long working hours can use 60% of the actual current, and electrical equipment with short working hours can use 60% to 100% of the actual current.

02) The color of the energy storage power wiring harness

The color and serial number are on the car's circuit. With the continuous increase in the number of automotive electrical equipment, the number of wires is also increasing. In order to facilitate the identification and maintenance of automotive electrical equipment, low-voltage wires in automotive circuits are generally composed of wires of different colors. On vehicle wiring diagrams, which are usually color-coded (indicated by one or two letters), the wires are usually different vehicle colors. Monochrome and color have two common selection principles. One of the color wires is the former and the latter is the complementary color.

03) Physical properties of the energy storage cable assembly

(1) The wire between the door and the door body should be a bent wire.

(2) The wires used in the high temperature resistant part are generally vinyl chloride or polyethylene coated wires with good insulation and heat resistance.

(3) In terms of shielding function, in recent years, more and more electromagnetic wave shielding circuits using weak signal cables have been used.

04) Bundle the power wiring harness

(1) The strength and insulation performance of the cable are greatly improved by adopting half-fold packaging, painting and drying processes.

(2) A new type of wire harness is placed inside the side-cut plastic bellows, partially wrapped in plastic to make it stronger and more protective, and it is more convenient to find faulty wires.

05) energy storage connector

Connectors are used to connect batteries. Common connectors include plugs, sockets, and connection blocks. Wires are used to transmit electrical energy, and their materials include copper, aluminum, etc. The protection device is used to protect the battery from overcharge, overdischarge, short circuit and other damages.

The energy storage connector control circuit is used to monitor the battery status, control the charging and discharging process, and ensure the long life and safety of the battery. The use of energy storage wiring harness can greatly improve energy utilization, reduce energy waste and environmental pollution.



On the whole, the value of energy storage has been recognized more and more, and the discussion on energy storage has become more and more heated. The difficulties faced by energy storage companies at this stage are:

First, technical capabilities need to be improved, and battery charging and discharging performance, safety and stability, and waste battery disposal issues need to be further resolved.

Second, there is a lack of effective market mechanisms and pricing strategies, and energy storage has not yet shown sufficient value in the electricity market.

Therefore, what energy storage companies can do is mainly to improve their technical level and track market progress.

Once the spot market is established, the pure peak-to-valley price difference arbitrage can evolve into the component time price difference arbitrage, and the utilization space of energy storage will increase accordingly; in the mature auxiliary service market, energy storage can participate in almost all auxiliary service varieties and obtain corresponding benefits ; With the in-depth advancement of projects such as demand-side response and micro-grid, the status of energy storage will also increase and become an important flexible resource in the system. The current energy storage projects are still far from large-scale applications, and the energy storage wiring harness is still There is a lot of space.
