For owners of Bombardier electric cars looking to enhance performance and address common issues, upgrading key components like the controller and instrument cluster can offer significant improvements. This guide explores a retrofit project focused on these critical Bombardier Electric Car Parts, detailing the process and benefits for enthusiasts and those seeking to improve their electric vehicles.
Many Bombardier Neighborhood Electric Vehicles (NEVs), especially older models, may encounter problems with their original instrument clusters and controllers. Finding suitable replacement parts is crucial to maintain and upgrade these vehicles. After experiencing ongoing issues with a 1999 Bombardier NEV’s instrument cluster and identifying the need for a new controller, a comprehensive upgrade was undertaken. Research revealed limited options for 72V separately excited shunt motor controllers. The Curtis 1244 series emerged as a leading choice, available in various amperage ratings (400A, 500A, and 600A) up to 80V. While sourcing a 400A unit proved challenging, a new 600A Curtis 1244 controller was acquired, paving the way for a significant system enhancement.
Controller Upgrade: Harnessing the Power of Curtis 1244
The Curtis 1244 controller is a popular choice for electric vehicle upgrades due to its robust features and programmability. A key consideration when integrating the Curtis 1244 into a Bombardier NEV is the voltage compatibility of control signals. The Curtis 1244 utilizes 72V control signals, whereas older NEVs often employ 12V systems. Therefore, an interface solution is necessary to bridge this voltage gap and ensure seamless communication between the vehicle’s control system and the new controller.
Instrument Cluster Retrofit: Modernizing the Display
To address the problematic electronic instrument cluster and modernize the vehicle’s feedback system, a custom solution was developed using relay logic. This system effectively replaces the original electronic cluster with a more reliable and potentially customizable setup. Complementing the relay logic, a programmable pulse input meter was incorporated to accurately display speedometer readings. This allows for precise speed indication, crucial for safe and efficient operation. Furthermore, a digital battery monitor was previously added to provide real-time insights into battery performance, a vital aspect of electric vehicle maintenance. While the rewiring process was extensive, the existing wiring harnesses offered sufficient capacity to accommodate the new components.
Enhanced Performance and Programmability
With the new controller and instrument cluster installed, the Bombardier NEV experienced a revitalization. The Curtis 1244 controller unlocks several advanced features, including programmable operating modes. Although the controller supports four modes, a three-mode selection was implemented using an SPDT switch, offering Drive, Golf, and a custom mode. One of the most significant improvements is the introduction of regenerative braking. The Curtis 1244 facilitates throttle/braking control, initiating regenerative braking upon throttle reduction and transitioning to plug braking at lower speeds. The braking intensity is programmable, effectively addressing the limitations of the original hydraulic brakes and enhancing overall braking performance.
To maintain safe operating parameters and motor longevity, the minimum shunt current was set to 3 amps, mirroring the original controller’s configuration. This setting limits the maximum level ground speed to approximately 31 MPH, as measured by GPS. While reducing the shunt current could increase top speed, it also elevates the risk of brush arcing and motor overheating, potentially shortening motor lifespan. The chosen 30 MPH limit provides a balanced approach, offering adequate speed for typical NEV applications while prioritizing motor health.
Technical Expertise and Considerations
This retrofit project highlights the potential for upgrading bombardier electric car parts to enhance the performance and reliability of older models. However, it’s crucial to acknowledge the significant technical expertise required for such undertakings. As stated by the individual who completed this project, it demands a strong foundation in automotive electronics and electrical systems, accumulated through years of experience and training. Attempting such modifications without adequate knowledge can lead to complications and potentially compromise vehicle safety and functionality.
Conclusion: Revitalizing Bombardier Electric Cars Through Part Upgrades
Upgrading bombardier electric car parts, specifically the controller and instrument cluster, can breathe new life into older Bombardier electric vehicles. The adoption of a Curtis 1244 controller and a custom instrument cluster solution demonstrates a pathway to improved performance, enhanced features like regenerative braking, and modernized vehicle operation. While the benefits are substantial, these projects are best suited for individuals with a strong technical background in automotive electrical systems. For those with the necessary skills, upgrading key bombardier electric car parts offers a rewarding opportunity to optimize and extend the lifespan of their electric vehicles.
