Honda’s new hybrid vehicle "Insight" exhibited at the Detroit Auto Show uses an IPU (Intelligent Power Unit) that integrates a nickel-metal hydride rechargeable battery pack and a drive motor inverter, which is compatible with the company’s "Civic Hybrid Compared with the IPU equipped with the car, the volume is reduced by 19% and the weight is reduced by 28%. Today, let’s talk about the changes to the Insight hybrid battery, the working principle, and its features.

The changes to the Insight hybrid battery

Since the output power of the Insight hybrid battery pack unit module has been increased by 30% compared to the original, the Insight hybrid battery modules equipped in the battery pack have been reduced from 11 to 7, thus achieving small size and lightweight. The module consists of 12 cylindrical units connected in series. The new Insight is equipped with a total of 84 units. The overall voltage of the battery pack is 100.8V, which is 57.2V lower than the Civic Hybrid. The unit is produced by Sanyo Electric, with a current capacity of 5.75Ah and a voltage of 1.2V. In addition, the Civic Hybrid is equipped with a unit produced by Panasonic, with a current capacity of 5.5Ah.

Working principle

The oxygen generated when the nickel hydroxide electrode is fully charged is diffused and recombined into the water on the negative electrode. It not only keeps the internal pressure of the battery constant but also prevents the electro-hydraulic concentration from changing greatly.

The Insight ni-mh battery is composed of nickel hydroxide positive electrode, hydrogen storage alloy negative electrode, diaphragm paper, electrolyte, steel shell, top cover, sealing ring, and so on. In a cylindrical battery, the positive and negative electrodes are wound together with separator paper and then sealed in a steel case. In the prismatic battery, the positive and negative electrodes are separated by separator paper and stacked in layers and sealed in a steel case.


The structure of the single Insight ni-mh battery is a sealed cylindrical shape with a nominal voltage of 1.2V. It has the following characteristics:

(1) Large capacity

The "energy storage density" of Insight ni-mh batteries, taking AA-size rechargeable batteries as an example, is at least 1000mAh or more, preferably up to 1400mAh. Under the same volume and weight, its capacity is 2 times ~3 times that of nickel-cadmium batteries, and more than 1 times more than traditional nickel-cadmium batteries.

(2) No "memory effect"

The "memory effect" refers to the fact that the Insight hybrid battery is charged without being fully discharged during use, resulting in abnormal oxides on the negative plate of the battery. It has an inhibitory effect on the Insight hybrid battery voltage, which means that the battery is fully charged but discharged. When the voltage drops sharply, the battery life is shortened. Insight ni-mh batteries have no "memory effect", but they self-discharge during use. Under normal use, the amount of power loss is 1% to 3% per day. A fully charged Ni-MH battery must be recharged after being used for a few weeks. Since the Ni-MH battery has no "memory effect", it does not need to be discharged before starting to charge it, and it can be charged at any point when it is used.

GK International Enterprises Co., Ltd has developed a variety of Insight hybrid batteries and conducted a lot of tests before leaving the factory to ensure quality. Insight hybrid batteries have many advantages over other products.
