2025,11,11

When electric vehicles are equipped with dual batteries, they often encounter difficult problems - the charging of the main and auxiliary batteries is unbalanced, the auxiliary battery has not been fully charged when the main battery is fully charged, which affects the overall range; after parking, the auxiliary battery consumes excessive power and becomes drained, making it impossible to start the vehicle next time; during connection of the circuit, it is prone to conflict with components such as Two-Wheeled Electric Vehicle Switch and Electric Vehicle Circuit Breaker, posing safety hazards. HUA GAO XIN KE's Dual Battery Isolator specifically addresses these issues, intelligently charging separately, preventing battery depletion, and can also be adapted to the circuits of electric vehicles, making the use of dual batteries more convenient and safer.

Product Description

HUA GAO XIN KE This Dual Battery Isolator is an intelligent control component specifically designed for the dual battery system of electric vehicles. It is controlled by a microprocessor chip and can automatically detect the voltages of the main and auxiliary batteries. Its terminals are made of brass, which has good conductivity and low contact resistance, and will not affect performance due to overheating. The device is small in size and can be flexibly embedded into the circuit box of the electric vehicle during installation, avoiding the installation positions of components such as Two-Wheeled Electric Vehicle Switch and Electric Vehicle Knob Gear Switch. No major modification of the original vehicle circuit is required. The shell is made of flame-retardant ABS material, which is resistant to high temperatures and has strong insulation properties, and can withstand vibrations and temperature changes during the vehicle's operation. It comes with a voltage display light, allowing the charging status of the main and auxiliary batteries to be clearly visible, without the need for additional instrument monitoring. Technical Specifications

The working voltage range of this dual battery isolator is 12V - 24V, which is suitable for the battery voltage specifications of most electric vehicles; the maximum continuous current is 60A, and the peak current is 120A, meeting the current requirements for simultaneous charging of the two batteries. The voltage detection accuracy is ±0.1V. When the main battery voltage is ≥ 13.8V, it automatically connects the auxiliary battery for charging, and when it is lower than 12.5V, it disconnects the auxiliary battery to prevent the main battery from being depleted; the charging balance is ≤ 3%, and the charging progress of the main and auxiliary batteries is basically the same, without the situation of one side being fully charged while the other is depleted. The working temperature range is -30℃ - 85℃, and it can work stably in both winter and summer with low temperatures or high temperatures; the protection level is IP65, and it will not get waterlogged and short-circuited in rainy or humid environments, suitable for outdoor driving scenarios. The response time is ≤ 0.5 seconds, and it can quickly switch states when there is voltage fluctuation to avoid overcharging or over-discharging of the batteries.

Product features and advantages

HUA GAO XIN KE Dual Battery Isolator has advantages that precisely meet the usage requirements of dual batteries. Firstly, intelligent split charging, automatically detecting voltage to control charging and discharging, and balancing the charging of the main and auxiliary batteries, which is more convenient than manual switching; secondly, anti-depletion, when the voltage of the main battery is low, it automatically disconnects the auxiliary battery to ensure that the vehicle can start normally and avoid the trouble of depletion; thirdly, circuit compatibility, it can be compatible with components such as Two-Wheeled Electric Vehicle Switch and Electric Vehicle Circuit Breaker, without modifying the original vehicle circuit, reducing installation risks; fourthly, durable and sturdy, with flame-retardant casing and IP65 protection, it can be used in vibration, high and low temperatures, and humid environments, with a lifespan three times longer than ordinary isolators; fifthly, intuitive and easy to use, the voltage display light provides real-time feedback on the status, and without professional knowledge, one can also determine the working condition, and beginners can also use it easily.

Application scenario

When this isolator is installed on an electric tricycle, the main battery powers the drive, while the auxiliary battery supplies the lights and the horn. The charging is balanced without any power loss, eliminating the need for frequent manual battery switching. For an electric motorcycle, the dual batteries are used together, and the isolator is installed away from the Two-Wheeled Electric Vehicle Switch. During long rides, the range doubles, and there is no fear of the auxiliary battery running out of power after parking. For electric vehicles, an additional auxiliary battery can be installed for emergency purposes, and the isolator is compatible with the Electric Vehicle Brake Power Off Switch, ensuring that the battery circuit safety is not affected during emergency braking. For electric trucks, it is used to connect the main and auxiliary batteries, with the main battery powering the drive and the auxiliary battery powering the in-vehicle refrigerator and navigation system. The charging is balanced without any delay in usage. It also ensures a long battery life of 1-2 years per battery. The isolator is resistant to moisture and temperature changes, and the dual batteries provide sufficient range for all-day operations. There is no need for frequent charging during use. It is durable, reducing the number of repairs and lowering the maintenance costs in the long run. For those who rely on electric vehicles for their livelihood, the stable dual battery system can also reduce downtime and indirectly increase income.

Customer Benefits

By choosing this dual battery isolator, the owner can save a lot of time and costs. The balanced charging extends the battery life and reduces the frequency of battery replacement. Each battery can be used for an additional 1-2 years. The isolator prevents power loss, eliminating the need for towing or rescue costs due to battery depletion, and saving unexpected expenses. The circuit is compatible without the need to modify the original vehicle wiring, reducing installation costs and the risk of circuit faults. The range doubles, meeting the needs for long-distance travel, and there is no need to frequently search for charging stations, enhancing the convenience of use. It is highly durable, reducing the number of repairs and lowering the maintenance costs in the long run. For those who rely on electric vehicles for their livelihood, the stable dual battery system can also reduce downtime and indirectly increase income.

Customer Reviews and Recommendations

Owner of the electric tricycle, Master Liu, said： "Previously， the charging of the dual batteries was always unbalanced. The main battery was full when the auxiliary battery was only half charged. After installing this isolator， the charging is particularly balanced. When the main battery runs out of power， it can automatically disconnect the auxiliary battery， and there has never been a situation where it couldn't start again. It doesn't conflict with the Two-Wheeled Electric Vehicle Switch either." Mr. Wang， the rider of the electric motorcycle， commented： "During long rides， the range is provided by the dual batteries. The isolator is installed away from the Electric Vehicle Knob Gear Switch， and it is IP65 protected， so it is fine in rainy days. The voltage display light makes it easy to understand the status. It has not failed for a year and is much more reliable than ordinary isolators." Shop owner Zhang recommended： "When installing dual batteries for customers， we always recommend this one. It has strong circuit compatibility， can be compatible with components such as Electric Vehicle Circuit Breaker， and is easy to install. Customer feedback is that the charging is balanced and there is no power loss. There are almost no售后 problems， and the reputation is particularly good."
