Modular EV Chassis Battery Module for Power and Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric vehicles face challenges in providing sufficient battery power for their components and long-distance driving due to the limitations of existing battery technologies.
Innovation Solution
A modular chassis system for electric vehicles, comprising a first module with a front axle, a second module with a container enclosing multiple battery assemblies connected to a power distribution unit, and a third module with a rear axle, allowing the battery assemblies to power components in the first and third modules via the power distribution unit, which can be integrated into existing chassis without redesign.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate power distribution units are used in different modules, then each module can operate independently, but the overall system weight and cost increase
Solution Approach 1:
The patent consolidates power distribution functionality into a single centralized power distribution unit located in the battery module, eliminating the need for separate power distribution units in the front and rear modules. This merging of functions reduces overall system weight and cost while maintaining reliable power supply to all vehicle components through the centralized unit.
2Use of energy by moving object
If battery power capacity is increased to support long-distance driving and multiple components, then vehicle range and component power availability improve, but the battery system becomes more complex and heavier
Solution Approach 1:
The battery module is designed to serve multiple functions simultaneously: it provides structural support as part of the chassis, houses the power distribution unit, and contains the battery assemblies. This multi-functionality allows the system to achieve high power capacity for long-distance driving and multiple components without proportionally increasing system complexity, as the same structural element performs multiple roles.
3Ease of manufacture
If existing chassis designs are retained without redesign, then development cost and time are reduced, but integration of new battery systems becomes difficult
Solution Approach 1:
The vehicle chassis is divided into modular sections including a front module, a central battery module, and a rear module. The battery module is designed as a self-contained unit with standardized interfaces that can be integrated into existing chassis designs without requiring complete redesign. This segmentation allows the new battery system to be adapted to existing platforms while maintaining manufacturing efficiency.

AI summary
A vehicle chassis system may comprise a first module comprising a front axle of a vehicle. The vehicle chassis system may comprise a second module comprising a container that encloses a plurality of battery assemblies. The vehicle chassis system may comprise a third module comprising a rear axle of the vehicle. The second module may be configured to be connected to and interposed between the first module and the third module. The chassis constructed with the second module provides torsional rigidity to the chassis.
