Vehicle Battery Mounting Structure Harness Length Optimization

The patent transitions from a one-dimensional linear arrangement (batteries in a row under the floor) to a two-dimensional arrangement by dividing batteries into two groups positioned at the front and rear of the vehicle. This dimensional change creates a new spatial configuration that allows the connection control device to be optimally positioned between the battery groups, reducing harness length while maintaining accessibility.

The battery system is segmented into two distinct groups: a first group positioned at the front under the floor and a second group positioned at the rear under the floor. This segmentation creates separate functional zones that allow the connection control device to be strategically placed between them, optimizing both operational accessibility and electrical connection efficiency.

The dense battery arrangement is segmented into two separate groups positioned at opposite ends of the vehicle (front and rear). This segmentation maintains high space utilization by filling the available under-floor volume while creating distinct zones that allow the connection control device to be positioned in an intermediate optimal location for operational access.

The patent utilizes the longitudinal dimension of the vehicle by positioning battery groups at both the front and rear extremes, effectively using the full length of the vehicle's under-floor space. This dimensional approach maximizes space utilization while creating optimal positioning opportunities for control devices along the longitudinal axis.
