In wet weather conditions, using a power wheelchair may raise concerns about leakage or electrical faults. Although modern electric wheelchairs are designed with the need to resist rain intrusion in mind, key parts such as batteries and controllers are specially waterproofed, and most products are marked with a moisture-proof rating to reduce the risk of short circuits or damage. However, in the face of extreme rainfall, such as persistent heavy rain or water depth exceeding a certain limit, electric wheelchairs may still damage internal electronic components due to moisture intrusion. If sensitive electrical components such as controllers and motors come into contact with large amounts of water, leakage or other malfunctions may result. Therefore, when driving an electric wheelchair on rainy days, you should try to avoid passing through waterlogged areas to ensure the effectiveness of waterproofing measures, and clean and dry the water-absorbing parts of the wheelchair in a timely manner. If there is no urgent need, it is recommended to reduce going out in extreme weather conditions to ensure the safety of users and the normal operation of the equipment. If possible, you can choose to install professional waterproof accessories or purchase electric wheelchair products with stronger waterproof performance to reduce risks.
