CJPT and Yamamoto to research replaceable cartridge batteries

Commercial Japan Partnership Technologies Corporation (CJPT) and Yamamoto Transport announced a new research program on the standardization and commercialization of replaceable and rechargeable cartridge batteries.

CJPT was launched in March 2021 by Toyota Motor Corporation with Isuzu Motors and Hino Motors and has since been joined by Suzuki and Daihatsu.

One of the main challenges of commercial battery electric vehicles (BEVs) is charging that takes longer than the refueling time for conventional petrol and diesel vehicles. This leads to an increase in logistical downtime when vehicles and freight are stationary. The introduction of commercial BEVs is also expected to lead to a potential increase in peak electricity demand on industrial estates when multiple vehicles are charged simultaneously.

To solve these problems, CJPT and Yamamoto Transport will begin to study the practical application of removable and portable cartridge batteries, based on a range of potential benefits:

Reduce the cost of introducing BEVs: Costs can be reduced by limiting battery capacity to meet actual range requirements. This can also reduce the total number of batteries required.

Reducing the need for charging infrastructure.

Reducing logistical downtime.

Electricity demand smoothing: Replacement batteries can be recharged while vehicles are in operation, reducing peak power demand.

CJPT plans to make plans for commercial BEVs that can be powered by cartridge batteries. The company believes that developing cartridge batteries and charging systems with common specifications for a range of commercial vehicles, from minivans to light trucks, will reduce their costs and encourage their widespread use. The company is also looking for ways to match battery usage with actual operational requirements to produce an efficient power management solution.

Yamamoto Transport is committed to building a green delivery ecosystem that includes its transportation and delivery suppliers, and is working with communities to create an electricity usage schedule based on the use of cartridge batteries. In addition to advancing the use of green power by closing the gap between the peaks in renewable energy generation and the timing of commercial BEV charging, the company also plans to explore ways to increase the resilience of communities to electricity supply. enlarge. This could, for example, be the supply of cartridge batteries to disaster areas where access to energy infrastructure is at risk.

The two companies are open to collaborating with new partners in the standardization and commercialization of cartridge batteries, in order to popularize electric vehicles and thus contribute to achieving a carbon neutral society.
