Data shows that the number of domestic new energy vehicles will reach 20.41 million in 2023, of which the number of pure electric vehicles will be 15.52 million, accounting for 76.04% of the total number of new energy vehicles.

When new energy vehicles are growing rapidly, charging infrastructure is also accelerating the layout. However, the problem of battery life is a lingering haze of new energy vehicles. Many new energy owners may have encountered scenarios where their vehicles ran out of power and broke down. At present, the nominal cruising range of new energy vehicles is mostly between 200km and 500km, but the actual cruising range is affected by factors such as weather, driving habits and driving road conditions, and there is a large deviation. Therefore, it often happens that new energy vehicles break down on the road or in parking lots due to insufficient power. If such a situation occurs, roadside assistance is the only option. Therefore, movement supplement plays an irreplaceable role as a supplement.

The V2V new energy vehicle road rescue tool is an innovative product designed to address the breakdown situations that new energy vehicles may encounter when driving due to insufficient battery.

V2V new energy vehicle road rescue tools are widely used in many fields, including insurance companies, 4S stores, online ride-hailing platforms, and operating fleets. The value of its products is mainly reflected in reducing rescue costs, improving rescue efficiency, improving store efficiency and saving car owners' time.

What is V2V charging?

V2V is actually the so-called vehicle-to-vehicle mutual charging technology, which can charge the power battery of another electric vehicle through a charging gun. There are DC vehicle-to-vehicle mutual charging technology and AC vehicle-to-vehicle mutual charging technology. AC cars charge each other. Generally, the charging power is affected by the car charger, and the charging power is not large. In fact, it is somewhat similar to V2L. DC-vehicle mutual charging technology also has certain commercial application scenarios, namely high-power V2V technology. This high-power vehicle-to-vehicle mutual charging technology is still good for extended-range electric vehicles.

Wanggu Intelligent Charging and Discharging Solution

  Dry Valley Group has developed a mature set of Dry Valley intelligent charging and discharging solutions (v2v charging solutions) in response to market development to meet the needs of many pile companies.

·Technical introduction:

1. Simulate the charging process of the power supply vehicle. After entering the charging stage, the power supply vehicle connects to the internal battery.

2. Close the high-voltage contactor on the power supply side and perform safety insulation monitoring at the same time.

3. The high voltage on the power supply side enters the charging rectifier module, providing power supply to the charging module and recharging the power supply battery at the same time.

4. Start charging the charging vehicle and charge the charging vehicle according to the requirements of the charging vehicle BMS.

Use scenarios of V2V charging

1. Road rescue emergency rescue can open up a new business for companies engaged in road rescue business, which is also an incremental market. When encountering a new energy vehicle with a power shortage, you can directly pull out the vehicle-to-car mutual charger placed in the trunk of the new energy vehicle to charge the other party, which is trouble-free and simple.

2. For emergencies on highways and temporary event sites, as a mobile fast-charging charging pile, it has the advantage of being free of installation and does not occupy space. It can be directly connected to three-phase power when needed, and can also be connected to the operating system for charging. During holiday peak travel, as long as the expressway company's transformer lines are sufficient, access to these mobile charging piles can greatly alleviate the charging pressure and management, operation and maintenance costs that used to be queued for four hours at a time.

3. Outdoor travel, if you are in a hurry on a business trip or traveling, or if you are in a new energy vehicle that only has DC charging, equipped with a mobile DC charging pile, you can safely take a trip on the go!

The value of V2V charging

1. Sharing economy: V2V charging can be part of the electric vehicle sharing economy. The electric vehicle sharing platform can provide sufficient power for the vehicle to be borrowed through charging, thus improving the availability of the service.

2. Energy balance: In some cases, some areas may have energy surplus, while other areas may be facing power shortages. Through V2V charging, electric energy can be transferred from areas of surplus to areas of shortage to achieve energy balance.

3. Increase the reliability of electric vehicles: V2V charging can increase the reliability of electric vehicles, because in some cases, a vehicle may not be able to drive due to battery problems, but with the help of other vehicles, it is still possible to continue driving.
