Troubleshooting electric drive failure and non-driving failure

When the electric drive system fault pops up on the electric vehicle instrument, the vehicle is directly prohibited from driving. Many faults belong to intermittent recessive faults, which are easier to trigger in bumpy road, rapid deceleration and alternating cold and hot environments. The static reading of fault codes in situ may not be able to reproduce. Combining with a large number of afte...

DCDC failure analysis

When many engineers encounter DC/DC fault alarm, the first reaction is to directly replace the DC/DC body or all-in-one assembly (all-in-one includes integration with OBC, PDU or MCU, etc.), and the owner is also easily advised to directly replace the parts. Comparing with the FTA fault tree of DC/DC faults, many faults are not rooted in the DC/DC itself, and blind replacement will only increas...

Troubleshooting intermittent CAN communication failure

Many engineers encounter this kind of problem: the charging function fails after the vehicle is powered on, the CAN communication fault of the charging system is diagnosed, and the fault code is repeatedly cleared, but it still fails to charge normally. Many people directly judge that the charger is damaged and replaced blindly, resulting in unnecessary waste. Combining with the fault tree, we can...

Selection and use of on-board debugging tools

In electric vehicle development and after-sale troubleshooting, CAN-bus data analysis is an important means to locate controller faults. Realize CAN bus test, simulation, message acquisition and recording, off-line playback and analysis, which is a necessary tool for vehicle controller, BMS, MCU and OBC debugging. Load the DBC database The DBC file is the parsing dictionary of the CA...

E-Z-GO ELiTE Lithium Battery and Charger: Compatibility Guide

E-Z-GO ELiTE Lithium Battery and Charger: Compatibility Guide If you are researching an E-Z-GO ELiTE lithium battery, an E-Z-GO battery replacement, or an E-Z-GO charger, it is easy to focus only on voltage and capacity. However, a modern electric golf cart is more than a battery connected to a motor. The battery, BMS, charger, controller, dashboard and other vehicle electronics work together a...

Best Club Car Alternatives : Which Golf Cart Offers the Best Value? Introduction Club Car has long been one of the world's leading golf cart brands, trusted for its quality and reliability. However, as buyers place greater emphasis on pricing, battery technology, customization, and long-term operating costs, many are now looking for a better Club Car alternative. Whether you're purchasing a sin...

Fault Detection Methods for Three-Phase Asynchronous Motors: Two-Step Test with Megohmmeter & Multimeter

In electric vehicle maintenance, industrial equipment operation & maintenance, and traction motor after-sales troubleshooting, motor fault diagnosis is a frequently used and core fundamental skill. On-site misjudgment of motor conditions often leads to repeated part replacement, ineffective commissioning, and even customer complaints. This article organizes a standardized testing pr...

A Complete Guide to LSV Batteries: Types, Lifespan, and Replacement

The battery is the heart of any electric Low-Speed Vehicle (LSV). Understanding battery technology, lifespan, and replacement options is essential for getting the most value from your LSV. This comprehensive guide covers everything you need to know about LSV batteries. Types of LSV Batteries Flooded Lead-Acid (FLA) Batteries Flooded lead-acid batteries are the most common type f...

From Jerky Launch to Silky Smooth — Regenerative Braking Calibration for a Middle Eastern Electric Shuttle

Background Following the success of the sightseeing shuttle project in South Africa, we deployed another 96V 15kW PMSM motor drive system in the Middle East. This time, the system was installed in a 20-seat electric shuttle bus used for resort transfers. The regional terrain is diverse, featuring both smooth asphalt roads and undulating slopes. During the initial commissioning phase, the custo...

From “Laggy Throttle” to “Instant Response” — A Remote Tuning Case Study of a PMSM Drive System for a South African Sightseeing Shuttle

Background Recently, a customer in South Africa purchased a sample unit of our 96V 15kW PMSM motor drive systemfor validation on a 16-seat electric sightseeing shuttle. After the customer completed mechanical installation and electrical wiring, the project moved into the commissioning phase. It didn't take long before feedback came in: the throttle response was laggy and disconnected from dri...
