Nippon Denso Announces Successful Development of New Lithium-Ion Battery Pack

On October 3, Denso Corp. stated that the company has successfully developed a lithium-ion battery pack that can improve the efficiency of start-stop systems for electric vehicles.

According to autonews, the current electric vehicle start-stop system uses brakes to shut down the engine and save fuel. As a parts supplier to Toyota Motor Corporation, Nippon Denso said that the company’s newly developed lithium-ion battery pack will allow the start-stop system to obtain more renewable power.

After storing the regenerative power, this new type of lithium-ion battery pack injects the regenerative power into the electrical and electronic components of the electric vehicle, such as the navigation or sound system in the vehicle, thereby reducing the amount of power generated by the alternator in the vehicle and reducing the total engine load. , improve fuel economy.

In addition, since the newly developed lithium-ion battery pack utilizes air cooling, the battery pack is not equipped with a dedicated cooling system. This design makes the battery pack lighter and more compact, and also allows the vehicle to obtain a more flexible assembly design. Japan Denso's battery pack is equipped with a management and control unit to monitor the battery voltage to prevent overcharging and discharging.

However, a spokesperson for Denso refused to disclose the name of the vehicle company that plans to use the battery pack.
